This future value calculator models how an investment might grow over time. It handles simple compounding, or more complex scenarios with regular contributions or withdrawals.

Future Value Calculator

Using the Future Value Calculator

The calculator starts with some simple defaults – provide three inputs to see compound growth in action.

  • Starting Balance ($) - Your initial investment amount
  • Years to Invest - How long you'll let it grow
  • Expected Annual Return (%) - Your assumed annual return rate. For context, the S&P 500 has historically averaged around 10% annually (see our S&P 500 return calculator for more)

Advanced Options

For more complex scenarios where you'd like to model regular contributions or retirement withdrawals, click Show Advanced Options to reveal the tool's Periodic Contributions settings.

  • Contribution Amount ($) - Enter either regular deposits you'll make as positive dollar amounts, or withdrawals you'll make as negative dollar amounts.
  • Contribution Frequency - How often you'll add to or withdraw from the investment: weekly, bi-weekly, monthly, quarterly, or annually.

The calculator updates automatically as you type – no button clicking required!

Understanding the Results

The calculator shows your Future Value prominently – that's the final number you care about, the total investment value after the Years to Invest you chose. Click Show Detailed Breakdown to see how you got there:

  • Starting Balance - Your initial investment
  • Your Contributions - Total amount you added over time (or withdrew, if negative)
  • Investment Gains - The money the investment made for you
  • Overall Return - Your total percentage gain

Graph Mode: Visualizing Growth Over Time

Hit Calculate & Graph 📊 to see a stacked bar chart showing how your investment grows year by year. The visualization breaks down your starting balance, contributions, and market gains to illustrate the compounding growth (or, uhh, decline) of an investment. You can hover – or tap on mobile – to see the snapshot after any year in the series.

Calculator Assumptions

The calculator uses annual compounding, meaning returns compound once per year. For periodic contributions, it applies growth each period proportionally (for example, monthly contributions receive monthly compounding at 1/12th the annual rate).

This tool shows you the mathematical outcome of consistent returns, which is useful for planning even if reality will be bumpier. And I guarantee it will be: real-world investing is messier than this calculator.

Planning Your Financial Future

Whether you're seeing what an investment might become or planning how to fund 30 years of retirement, playing with different scenarios helps you understand the possibilities. Despite my best attempts, my calculators can't predict the future... but modeling sure beats guessing!

Below is an industry performance screener and industry stock comparison tool to analyze and compare the performance of companies within the same industry classification. Search by individual ticker or company name, SIC code, NAICS code, or Fama-French 12 industry classification to see performance metrics, charts, and peer comparisons.

Industry Performance Screener and Comparison Tool

How to use the Industry Performance Screener

The screener offers multiple ways to analyze companies and industries. You can search by individual ticker or company name, or explore entire industry classifications using various taxonomy systems.

Search methods and classification systems

For the tool to work, you'll need to pick an industry to screen. But don't worry, I made that straightforward – choose from four classification approaches:

  • Individual Ticker: Enter any valid stock ticker in DQYDJ's database to find companies in the same industry and see peer comparisons. You can also search by name
  • SIC Codes: Use Standard Industrial Classification codes (e.g., "3571" for Electronic Computers) to find companies by business activity
  • NAICS Codes: Search using North American Industry Classification System codes for detailed industry breakdowns
  • Fama-French Industries: Select from the 12-industry classification system introduced by Fama and French

Fama-French 12 Industry classification

The Industries tab uses the Fama-French 12 industry classification system, developed by Eugene Fama and Kenneth French. This system groups companies into these sectors:

  • Consumer Staples (NoDur): Non-durable consumer goods
  • Consumer Discretionary (Durbl): Durable consumer goods like cars and appliances
  • Manufacturing (Manuf): Industrial manufacturing and machinery
  • Energy (Enrgy): Oil, gas, and energy companies
  • Chemicals (Chems): Chemical and materials companies
  • Technology (BusEq): Computers, software, and electronic equipment
  • Telecommunications (Telcm): Phone, internet, and communication services
  • Utilities (Utils): Electric, gas, and water utilities
  • Retail (Shops): Wholesale, retail, and some services
  • Healthcare (Hlth): Medical equipment, drugs, and healthcare services
  • Financial Services (Money): Banks, insurance, and real estate
  • Other: Companies not classified in the above industries

If you click over to the Industries tab in the search box, you can select one of those 12 and populate the table.

Aggregating by SIC and NAICS codes

The tool supports both SIC and NAICS classification systems:

  • SIC Codes: The older Standard Industrial Classification system, still widely used. For example, SIC 6021 represents National Commercial Banks
  • NAICS Codes: The newer North American Industry Classification System with more detailed subcategories. Example: NAICS 541511 for Custom Computer Programming Services

The tool automatically suggests matching codes as you type, helping you find the right industry classification. Alternatively, look up a ticker in the SIC and NAICS lookup tool first, then bring the SIC or NAICS codes you're interested in researching back here.

Performance metrics and analysis

For each company in your selected industry, the screener displays:

  • Current Price: Latest stock price from market data
  • 1-Year Return (%): Total return over the past 12 months
  • YTD Return (%): Year-to-date performance
  • 1-Year Price Chart: Interactive sparkline showing price movement over the past year
  • Company Information: Company name, exchange, and security type
The Industry Performance Screener showing Technology companies.

Additional metrics available

I've also built the tool to have a few columns off by default. Click the column visibility controls to reveal additional performance metrics:

  • 3-Month Return (%): Quarterly performance showing recent trends and momentum
  • 1-Month Return (%): Short-term price movement for identifying recent catalysts
  • 30-Day Volatility (%): Annualized volatility measure indicating price
    stability and risk

Advanced features and interactivity

But wait, there's more! You probably would have discovered these clicking around, but if you want to take your analysis further:

  • Sortable Columns: Click any column header to sort companies by that metric
  • Bulk Comparison: Select multiple companies to compare their performance side-by-side
  • Detailed Perofmance: Click through to individual stock returns by hitting the link exposed via the ticker
  • Export data: Export your data to a CSV to run your own analysis

Sources for the Industry Performance Screener

The tool integrates multiple authoritative data sources to provide comprehensive industry analysis:

Data Sources and APIs

Rate Limits and Usage

There's a lot of data here, and as you can imagine the tool is doing quite a bit in the background. that in mind, there are some mild usage limitations:

  • Market data may be up to 7 days old (though I do strive to update popular queries every 24 hours)
  • Industry screener usage: there is a maximum number of actions you can take per minute and per day. Come back tomorrow if you hit the limit (remember: you can also export data and do calculations offline)
  • Large industry groups may take 30-60 seconds to fully load as data is processed

Limitations and Disclaimers

Industry classifications and performance metrics are for informational and research purposes only. I cannot warrant the accuracy of industry groupings or performance calculations. You should work with a financial professional before making any investment decisions and verify all figures from other sources.

Important limitations include, but are not limited to:

  • Industry classifications may not reflect current business mix for diversified companies
  • Performance calculations are idealized and don't account for transaction costs, taxes, or timing
  • Splits, spinoffs, and other corporate events can affect ranking in the tools
  • Historical performance does not guarantee future results
  • Data may contain errors or omissions from source providers

Understanding Industry Analysis for Investment Research

Industry analysis is a fundamental component of investment research. The financial media doesn't generally talk about performance until after it's already happened and pretty obvious from online conversations. If there's an edge out there, you need to do differentiated research to find it.

I'm not just making this up – you're all the way into my conclusion, after all! – but working through this tool's development gave me a lot of investment ideas to pursue in various sectors.

Anyway, here's my take on where you might use this:

  • Identify Industry Peers: Find companies outperforming – or underperforming – their peers
  • Spot Trends: Understand at a glance whether industries are growing or declining
  • Assess Relative Value: Compare performance metrics across similar companies
  • Diversification Planning: Understand sector concentration in portfolios

Let me know how you use the tool – and send me your ideas for enhancements! Consider this a draft of what this tool might become.

How to analyze ETF correlations

Begin by entering at least two ETF symbols and selecting your analysis timeframe. The calculator will process correlations using daily return data to help you understand fund relationship dynamics and identify any portfolio overlap.

ETF selection and analysis setup

The ETF correlation interface is designed for efficient fund analysis:

  • ETF Symbols: Enter valid ETF tickers (e.g., SPY, VTI, QQQ) for any exchange-traded fund. Bulk input is supported: paste multiple symbols separated by commas or line breaks (up to 10) to speed things up
  • Analysis Timeframe: Select from convenient presets (YTD, 1Y, 2Y, 5Y) or choose custom date ranges extending up to 10 years
  • Fund Comparison: Compare up to 10 ETFs to understand correlation patterns across your portfolio

Understanding ETF correlation results

The calculator displays results through two complementary views: an interactive correlation matrix and detailed statistical analysis.

  • ETF Correlation Matrix: Displays pairwise correlations between all selected funds with intuitive color-coding to identify potential overlap issues
  • Portfolio Overlap Metrics: Calculates average correlation levels, identifies the most and least correlated ETF pairs, and measures correlation distribution
  • Relationship Consistency: Identifies which ETF pairs maintain stable correlations (and those with changing relationship dynamics)
  • Trend Visualization: Hover over correlation values to access rolling correlation charts and relationship strength interpretations

Interpreting ETF correlation values

ETF correlations reveal how fund returns move relative to each other during your selected period:

  • +0.8 to +1.0: Extremely high correlation - funds likely track similar indices or markets (read: potential redundancy)
  • +0.6 to +0.8: High correlation - funds probably share significant overlap in holdings or factors
  • +0.3 to +0.6: Moderate correlation - likely some shared factors but meaningful differences
  • -0.3 to +0.3: Low correlation - funds provided good diversification benefits historically
  • Below -0.3: Negative correlation - funds tend to move in opposite directions

Saving ETF correlation analysis

ETF correlation data and methodology

These ETF correlation calculations use the Tiingo API with these constraints:

  • ETF price data is updated within 7 days of market close
  • Fair usage limits for system performance:
    • 50 correlation analyses per day
    • 10 analyses per minute
  • Maximum 10 ETFs per correlation analysis
  • Historical analysis is limited to 10-year maximum timeframes

ETF correlation computation methodology

My ETF correlation analysis tool follows (as far as I know...) industry-standard practices for fund comparison:

  • Calculates daily percentage returns for each ETF
  • Synchronizes data and returns to overlapping trading dates across all selected funds (don't worry, it reports timeframes below the analysis)
  • Computes Pearson correlation coefficients between ETF return series
  • Analyzes correlation stability using rolling windows to identify relationship changes over time

ETF analysis limitations and considerations

ETF correlations reflect historical relationships and past correlations cannot guarantee future fund relationships.

This calculator serves educational and research purposes only. Results do not constitute investment advice and require independent verification before making fund allocation decisions.

ETF correlations can shift dramatically due to changes in underlying holdings, index methodology modifications, or market regime changes. My tool's analysis does not account for tracking errors, or fund-specific events that may affect relative performance.

Technical support and feature suggestions

Contact us if you encounter calculation errors or unexpected results. Include the specific ETF symbols and date range that produced issues.

I welcome suggestions for improving the ETF correlation calculator. But, keep in mind this is a free, ad-supported service. Significant feature additions may require consulting engagements. Your feedback helps me enhance the tool for all users, though, so if you have a broadly applicable suggestion I might add it.

ETF correlation in modern portfolio theory

ETF correlation analysis is fundamental to efficient portfolio construction.

Consider that many sector ETFs, despite tracking different industries, may show high correlations during certain market periods due to shared sensitivity to factors like interest rates, economic growth, or investor sentiment. Similarly, international ETFs may become highly correlated with domestic funds during global market stress.

Supplement your ETF correlation analysis with these portfolio evaluation tools:

Avoiding ETF overlap and redundancy

While ETFs were designed to provide instant diversification, many investors inadvertently create concentrated portfolios by combining funds with high correlations. Understanding these relationships helps you build portfolios that truly capture different return drivers... rather than expensive duplications of the same market exposures.

Presented here is a mutual fund correlation calculator which analyzes daily return correlations between actively managed and index mutual funds. The analysis can extend to thousands of mutual funds including domestic and international equity funds, bond funds, sector funds, and balanced funds.

Analyzing mutual fund correlations

Start by selecting at least two mutual fund tickers and defining your analysis period. The calculator will compute correlations using daily return data to reveal past fund return relationship patterns... and any potential redundancies.

Mutual fund selection and configuration

The mutual fund correlation interface provides a few inputs for your analyzing pleasure:

  • Fund Symbols: Enter valid mutual fund tickers (e.g., FXNAX, VTSAX, VTIAX) for any mutual fund in the Tiingo data set. Also, try pasting multiple symbols separated by commas or new lines (up to 10)
  • Time Period Selection: Choose from quick presets (YTD, 1Y, 2Y, 5Y) or define custom date ranges up to 10 years
  • Portfolio Scope: Analyze up to 10 mutual funds simultaneously to understand correlation patterns across your complete fund-based investment strategy

Interpreting mutual fund correlation data

Results are presented through two perspectives: an interactive correlation matrix and comprehensive fund statistics.

  • Fund Correlation Matrix: Presents pairwise daily return correlations between all selected mutual funds with visual indicators for overlap assessment
  • Fund Overlap Analytics: Computes average correlation across funds, identifies most and least correlated fund combinations, and measures correlation ranges
  • Management Style Analysis: Determines which fund pairs maintain consistent correlations (suggesting similar strategies... or circumstances) versus those with variable relationships
  • Dynamic Visualization: After running, hover over correlation values for rolling correlation trends and detailed relationship explanations

Mutual fund correlation value meanings

Mutual fund return correlations indicate how fund returns moved relative to each other throughout your analysis timeframe:

  • +0.8 to +1.0: Very high correlation - funds likely have similar holdings or track comparable benchmarks
  • +0.6 to +0.8: High correlation - funds probably share significant investment themes or market exposures
  • +0.3 to +0.6: Moderate correlation - some overlap but perhaps some meaningful diversification benefits remain
  • -0.3 to +0.3: Low correlation - funds have historically provided substantial diversification
  • Below -0.3: Negative correlation - funds tend toward opposite performance (excellent for risk reduction)

Active management and correlation analysis

Many actively managed funds show high correlations with their benchmarks or similar funds, suggesting limited differentiation despite higher fees – there's even a nickname for this phenomenon: shadow indexing. Conversely, funds with consistently low correlations may indicate genuine active management or unique investment approaches.

You can use correlation analysis as one input to assess whether your fund selections justify their costs. If multiple funds in your portfolio show correlations above 0.8, consider whether you're paying multiple management fees for the same market exposure.

  • Mutual fund pricing data updated within 7 days of fund NAV publication
  • Usage parameters for optimal system performance:
    • 50 correlation calculations per day
    • 10 calculations per minute
  • Maximum 10 mutual funds at a time
  • Analysis periods capped at 10 years

Mutual fund correlation calculation approach

Here's how the mutual fund correlation calculator works:

  • Determines daily percentage returns using net asset value data for each mutual fund
  • Aligns data to common valuation dates across all selected funds
  • Applies Pearson correlation methodology to calculate correlation coefficients between fund return series
  • Generates stability metrics using rolling correlation windows to evaluate relationship consistency over time

Mutual fund analysis disclaimers and limitations

Mutual fund correlations are based on historical performance data and past relationships do not predict future fund correlations.

This calculator provides research and educational information only and should not be considered financial advice. Always verify results independently... and consult qualified professionals for investment decisions, don't ask me.

Mutual fund correlations can change due to manager turnover, strategy shifts, or changes in underlying market conditions. The analysis does not consider fund-specific events that may impact relative performance between funds – though it does use daily value, so it should account for fees (but not backend or frontend loads).

Stock correlation analysis in portfolio construction

Understanding stock correlations helps you build resilient equity portfolios. Many investors make the mistake of thinking they're diversified simply because they own stocks in different sectors, but running a historical correlation analysis (like the one I'm showing you here!) often reveals surprising relationships that sector classifications miss.

For example, large-cap growth stocks across different sectors (technology, consumer discretionary, healthcare) often show high correlations because they're driven by similar macroeconomic factors: interest rates, growth expectations, and institutional investment flows. A portfolio of technology and healthcare stocks might seem diversified but could show correlations above 0.8 during certain market periods.

We've also got these slick portfolio tools:

Beyond sector diversification

Use this stock correlation calculator to move beyond superficial diversification. Instead of relying on sector labels, this tool will help you focus on actual return relationships to build portfolios that can perform across various market environments. But remember: the goal isn't necessarily to eliminate correlated equities, but to understand the story behind the story... so you can make informed portfolio construction decisions.

Below is a security correlation calculator which analyzes daily return correlations between stocks, ETFs, and mutual funds. Use this tool to identify portfolio diversification opportunities, measure how securities move together, and optimize your investment strategy based on return correlation relationships.

How to use the correlation calculator

To begin, select at least two securities and specify a date range. The tool will calculate correlations based on daily return data and give you the input you need for your comprehensive portfolio analysis.

Basic correlation inputs and security selection

The correlation calculator interface provides intuitive controls for portfolio analysis:

  • Security Types: Choose between Stocks, ETFs, and Mutual Funds - or combine multiple types for comprehensive analysis
  • Ticker Input: Enter valid security tickers (e.g., AAPL, SPY, VTSAX) across security types. As a shortcut, you can paste comma separated or newline separated lists of tickers (up to 10) to auto-populate the field. The tool also provides intelligent autocomplete, and (bonus) smart suggestions for stocks based on NAICS codes
  • Date Range: Select your analysis period with convenient presets (YTD, 1Y, 2Y, 5Y) or your choice of custom dates. The tool will allow you to manually set a window of up to ten years
  • Maximum Securities: Analyze up to 10 securities simultaneously for complex portfolio correlation analysis

Sample Security Correlation Calculator run for AAPL, SPY, and VTSAX

If you add an individual stock to your analysis, the tool includes intelligent suggestions based on industry classifications (NAICS/SIC codes). When you add securities, the calculator identifies related companies in the same industry for enhanced portfolio analysis. When the tool has smart suggestions, you'll see a lightbulb icon next to the Add button. Hit the lightbulb to select related securities.

  • Industry Analysis: Automatically suggests securities in the same NAICS industry group – or multiple groups for multiple tickers
  • Sector Diversification: Identify potential portfolio overlaps and diversification opportunities
  • Smart Filtering: Suggestions adapt based on your current security selection and NAICS codes

Interpreting correlation results and statistics

The correlation calculator provides two main result views: a correlation matrix and detailed statistics.

  • Correlation Matrix: Interactive table showing pairwise correlations between all selected securities (-1.0 to +1.0)
  • Market Relationship Metrics: Average correlation, correlation range, and most/least correlated pairs
  • Stability Analysis: Identifies which security pairs have the most stable vs. volatile correlation relationships over time
  • Visual Tooltips: Hover over correlation values to see 30-day rolling correlation charts and relationship descriptions

Understanding correlation values

Correlation values range from -1.0 to +1.0 and indicate how securities move relative to each other:

  • +1.0: Perfect positive correlation - securities move together identically
  • +0.5 to +0.8 (and up): Strong positive correlation - securities often move in the same direction
  • 0.0: No correlation - securities move independently
  • -0.5 to -0.8 (and down): Strong negative correlation - securities often move in opposite directions
  • -1.0: Perfect negative correlation - securities move in exactly opposite directions

The correlation calculator helps you optimize portfolio construction by identifying securities that move independently (or together, depending on your goals here!). Lower correlations between holdings can reduce overall portfolio volatility while maintaining return potential.

You can use the tool to avoid concentration risk – at least, based on past relationships. Securities with correlations above 0.8 may provide less diversification benefit than expected. Conversely, securities with correlations below 0.3 can provide diversification opportunities.

Exporting and sharing correlation data

The tool includes export functionality to save your correlation analysis for future reference or portfolio management software integration. Exported data includes the full correlation matrix, summary statistics, and date range information. Hit the Export button to download a CSV with your results.

Source and methodology of the correlation calculator

The tool uses the Tiingo API for comprehensive security data. We have implemented reasonable usage limits:

  • Security data may be up to 7 days old.
  • There are rate limits in place for usage:
    • Maximum 50 correlation calculations per day
    • Maximum 10 calculations per minute
  • Maximum 10 securities per correlation analysis
  • Maximum 10 years date range to ensure reasonable processing time

Correlation calculation methodology

Correlations are calculated using daily return data based on adjusted closing prices. The tool:

  • Calculates daily percentage returns for each security
  • Aligns data to common trading dates across all selected securities
  • Computes the Pearson correlation coefficients between return series
  • Generates stability metrics based on rolling correlation windows

Limitations and disclaimers

Correlation analysis is based on historical data and past correlations do not guarantee future relationships.

The tool is for informational and research purposes only. We cannot warrant the results. Verify any information from this tool independently.

Correlation relationships can change rapidly during market stress, economic shifts, or company-specific events – as folks sometimes say, "everything tends to fall together".

We do not account for corporate actions, stock splits occurring after or before data updates, or other events that might affect correlation calculations. The analysis assumes securities trade on the same market hours and does not adjust for trading calendars.

Bug reports, feature requests, and support

Contact us if you find calculation errors or data issues. Include the specific tickers and date range that caused problems so we can investigate, and possibly pass information back to our provider.

For feature requests, remember this tool is maintained as a free, ad-supported service. Significant feature requests require consulting arrangements. But I'm happy to hear you out if you have ideas, please send them in.

Correlation analysis and portfolio construction

We built this correlation calculator to address a fundamental challenge in portfolio construction: understanding how securities move together, not just how we think securities should move together.

Too many investors build portfolios based on asset class labels or industry groups without even considering past correlations. A "diversified" portfolio of large-cap growth stocks might have correlations above 0.9 - providing little actual diversification. Or, that super expensive, well-marketed ETF might be a shadow index of a cheaper fund, (or worse – it might capture the downside of an index and a fraction of the upside).

Compare your results with our other portfolio analysis tools:

Correlation is not causation (But it might matter)

Remember the classic warning: "correlation does not imply causation". Securities can be highly correlated – statistically – for all sorts of reasons that don't necessarily reflect something about their business relationship.

For portfolio construction purposes, though, correlation relationships matter more than correlation causes. Whether Apple and Microsoft move together because they're both technology stocks or because institutional investors treat them similarly, the portfolio impact is the same.

Use this tool to move beyond portfolio construction based on sector labels or market capitalization. Focus on actual return relationships to build truly diversified portfolios that can weather various market conditions.

We hope the correlation calculator helps you build better-diversified portfolios. Remember: the goal isn't necessarily to find uncorrelated assets - it's to understand the past relationships between your holdings.

Limitations to Consider

SIC codes offer valuable classification information, and I get them from SEC's EDGAR. Still, you need to be aware of some limitations. I touched on them in the company SIC and NAICS lookup tool, but here's a summary:

  • The SIC system was last updated in 1987. Even at the time it was having a hard time keeping up with modern industrial development, so may not accurately reflect modern industries. That goes particularly for technology. (Try code 7389 for a funny example!).
  • Companies self-report their SIC codes.
  • Complex companies with diverse operations are limited to a single SIC code in SEC filings.

I use the SIC codes to populate NAICS codes for each company. They don't map 1:1 in my database, so the NAICS codes can also be funny. But for a more comprehensive view, consider using both this SIC industry lookup tool and our NAICS industry lookup tool in your research.

SIC Code structure

The current tool only allows you to search by 4 digit SIC codes, without aggregating. I'll look into how best to add 2 and 3 digit searches to the tool (or feel free to get in touch with ideas).

SIC codes use a four-digit hierarchical structure:

  • First two digits: Major Group (Division or Sector)
  • First three digits: Business or Industry Group
  • All four digits: Specific Industry, or Specialization

For example, SIC code 7372 breaks down as:

  • 73: Business Services
  • 737: Computer and Data Processing Services
  • 7372: Prepackaged software

Sources

The key for these company classifications is their self-filed SIC. Here is how I populate the data:

  • SEC EDGAR: Primary source for company SIC codes and basic information.
  • NAICS Association: NAICS-SIC code crosswalks and NAICS descriptions come from the NAICS Association.

Below is a comprehensive SIC and NAICS code lookup tool for United States publicly traded securities. This tool helps investors understand company classifications, industry groupings, and related companies using both the legacy SIC (Standard Industrial Classification) system and the modern NAICS (North American Industry Classification System) codes.

The database includes all publicly traded securities that file with the SEC, with classifications updated directly from SEC EDGAR filings. Data is refreshed regularly as companies file new documents.

This tool is part of our public company industry classification suite. Please let me know about issues on our Contact Form.

SIC and NAICS Code Lookup Tool

Note: Industry classifications are self-reported by companies in their SEC filings. Some companies may have multiple NAICS codes – there isn't an official 1:1 mapping.

Basic SIC Lookup tool features

  • Ticker Search: Enter a company's ticker symbol to find its classification. The tool shows the company's SIC code as filed with the SEC, and for most codes will guess at a NAICS code (or codes) based upon the SIC.

Tool outputs

After you run the tool, you'll see a few things:

  • Company information: see the last stock price per share (and daily return and volume), the exchange the security is traded on, the type of security, the currency it trades in, and the company CIK (Central Index Key with the SEC) code. You'll also find a quick link to the most recent SEC filings for the company.
  • SIC Classification: find the company SIC code and a description of the industry. Click the SIC code to go to the SIC Industry Lookup tool and see related companies.
  • NAICS Classification: find the related NAICS Codes and NAICS industry descriptions for a given SIC code. Note that not all SIC codes have a mapping in the crosswalk... and some have many (see, for example, UBER). Click a NAICS code to see related companies by NAICS code in the NAICS industry lookup tool.
  • Company Description: find the company's description of its own operations. I source this data from Tiingo's Meta API.

Here's an example run of the tool for Apple Inc:

Why Two Classification Systems?

The tool shows both SIC and NAICS codes because both systems remain relevant for different purposes in financial analysis and regulatory compliance.

SIC Codes: legacy but still relevant

The Standard Industrial Classification (SIC) system – despite being officially replaced by NAICS in 1997 – remains important for several reasons:

  • SEC Filings: Some Government agencies – including, most relevant for this website(!), the SEC – still use SIC codes. The U.S. Securities and Exchange Commission requires companies to report SIC codes, making them a standard reference in securities filings
  • Historical Analysis: SIC codes have a long history, so they enable consistent historical analysis of industries going back many decades
  • Financial Software: Many financial databases beyond the SEC and analysis tools still use SIC codes for industry classification
  • Broad Categories: The simpler four-digit system makes it easier to group similar companies at a high level (the 2022 NAICS ranges up to 6 digit codes)

The first 2 digits of SIC are the major group for the company (there are 11). The first three group the industry, while the first four digits designate the industry itself.

A SIC History

The first edition of the Standard Industrial Classification was developed in the 1930s, and the Office of Management and Budget (OMB) last updated the SIC in 1987.

Rapid industrial development in the early 90s made it (more) evident the SIC wasn't equipped to deal with a changing economy. The US tasked the Economic Classification Policy Committee (with representatives from the Bureau of Economic Analysis, Department of Commerce, Bureau of the Census, Department of Commerce, the Bureau of Labor Statistics, and the Department of Labor) with establishing a "revised SIC". Instead, working with Statistics Canada and Instituto Nacional de Estadística, Geografía e Informática (INEGI) of
Mexico, we three allies harmoinized our classification systems in the NAICS.

The 1997 and 2002 releases of the NAICS come with correspondance tables for converting from the SIC, though later editions leave it up to us. I used the NAICS Association's crosswalk in the tool, though there are (of course!) other valid options for converting between the two.

NAICS Codes: modern and detailed industry classifications

The North American Industry Classification System (NAICS) modernized our approach to industry classification:

  • Greater Detail: Six-digit codes provide more granular industry classifications. The first two digits denote the sector a business belongs to (for example, "11" is Agriculture, Forestry, Fishing and Hunting), and subsequent digits divide an industry further.
  • Multiple Classifications: Companies can list multiple NAICS codes to reflect diverse operations
  • Modern Industries: Regular updates capture new and emerging industries, especially in technology and services

As I mentioned above, NAICS replaced SIC in 1997. Canada, Mexico, and the United States of America harmonized their data for NAICS, so NAICS codes are valid across the three neighbors. Public companies listed on US Stock Exchanges don't file their NAICS codes with the SEC, so this tool uses a crosswalk from the NAICS Association to guess the mapping.

Source and Methodology

The tool sources its data from multiple authoritative sources:

  • SEC EDGAR: Primary source for company SIC codes and basic information. Note that I only update company information once every 30 days to ease the burden on SEC systems.
  • NAICS Association: NAICS-SIC code crosswalks and NAICS descriptions come from the NAICS Association.
  • Tiingo: Tiingo provides pricing and volume data and other security metadata.

Limitations and Disclaimers

While we strive for accuracy, you should be aware of some limitations:

  • SIC codes are self-reported by companies, and codes determine how the SEC reviews company filings
  • The tool only updates company metadata at most every thirty days. I have the tool list the last time metadata was refreshed.
  • There isn't a 1:1 mapping of NAICS codes and SIC codes. You may have multiple NAICS codes per company... or none.
  • Officially, you might find company NAICS codes with other databases (or on tax returns or other agency documentation). This tool only uses a SIC to NAICS crosswalk to guess NAICS codes. These are not official codes, but should get you started.

The Significance of Moving Averages

Moving averages serve as a crucial tool in technical analysis, helping to smooth out price fluctuations and reveal underlying trends in mutual fund performance. By filtering out short-term volatility, moving averages offer a clearer picture of a fund's overall direction.

A popular analytical approach involves comparing two moving averages of different lengths, such as 50-day and 200-day periods. When the shorter-term average crosses above the longer-term one, it may indicate a bullish trend (often called a "golden cross"). Conversely, when the shorter-term average dips below the longer-term average, it could signal a bearish trend (known as a "death cross").

To deepen your understanding of moving averages and their role in financial analysis, we recommend exploring the Investopedia guide on Moving Averages.

Why Moving Averages Matter

Moving averages are a technical analysis tool you can use to smooth out price data and identify trends in ETF prices. They help filter out noise from short-term price fluctuations and provide a clearer picture of the overall trend.

A common strategy is to use two moving averages of different lengths, such as the 50-day and 200-day moving averages. When the shorter moving average crosses above the longer one, it can signal a bullish trend (known as a "golden cross"). Conversely, when the shorter moving average crosses below the longer one, it can signal a bearish trend (known as a "death cross").
