On this page you’ll find a calculator which is the first of its kind – a Graham Number calculator which automatically fetches information from SEC filings and populates fields for you to easily screen your stocks by Graham Numbers.
Just enter the ticker, click the ‘Populate Stock Fundamentals’ button, and we will attempt to get stock fundamentals from SEC filings via Quandl’s excellent API. For some stocks, this will fail (usually non-NASDAQ/NYSE stocks, and many financial services firms) – for these we fall back on Yahoo YQL for book value and earnings per share, and use the 50 day moving average for the stock price.
Automatic Graham Number Calculator for Stock Screening
Editor: We know, you don’t have to email – many stocks are failing because of the Yahoo! Finance YQL changes. We’ll update this when we have a workaround for you. For now, you’ll have to enter values manually.
Once you click ‘Calculate Graham Data’, we’ll instantly do the math on the stock’s inherent value according to the Graham number, and we’ll also calculate the deviation from fair value. Remember, positive is ‘bad’ here – if you have a new enough browser, we turn the field red for “Overvalued” and green for “Undervalued”.
For more information on the (Benjamin) Graham number, see the excellent entry in Wikipedia. We also have other calculators which are also useful while picking investments:
- A dividend discount model and cash flow model valuation calculator, that is also automatic
- A dividend reinvestment calculator for any stock to check how dollar cost averaging worked on a stock.
- A S&P 500 dividend reinvestment calculator which is perfect for benchmarking
We hope you’ll bookmark all four, and come back often… please let us know if you have other ideas for investment calculators, and let us know if you liked the Graham Number calculator!
Special thanks to our friend Evan at My Journey to Millions for the idea to create this calculator.
