The 2017 S&P 500 Return: Buy, Hold and Reinvest
The above quoted numbers are accurate if you bought the index at the opening price on January 3rd, 2017 and sold at the closing price on December 29, 2017. If you'd prefer the numbers buying at the December 30, 2016 closing price the return would be +19.42% and +21.83%, respectively.
Here are the index price returns:
|Price Return From||Open||Close||Gain|
|Jan 3, 2017 Start||2251.57||2673.61||18.74%|
|Dec 30, 2016 End||2238.83||2673.61||19.42%|
Following are the dividend reinvested returns:
|Dividend Reinvested Return From||Open||Close||Gain|
|Jan 3, 2017 Start||4303.12||5212.76||21.14%|
|Dec 30, 2016 End||4278.66||5212.76||21.83%|
Whichever set of return time-spans you prefer, the message is the same as last year's: dividends matter. If you invest in funds or stocks that pay a dividend you'll have to choose what to do with the payouts. Simply quoting price returns without regard to real returns in cash form doesn't reveal the true impact of an investment.

The 2017 S&P 500 Return
Adding dividend reinvestment to the math moved the needle from under 20% to over the psychological barrier. (Due to round number bias, it's a significant difference to us humans). It's also the right way to look at the returns.
Unless you burned the dividends you received in 2017, you had to make some decision on what to do with that cash. Nowadays, many investing accounts allow you to automatically reinvest these dividends, giving you returns that closely approximated the numbers quoted here.
Of course, your mileage may vary. Taxes, slippage, timing, fees, availability and other factors would have changed your exact results... but the point remains. Dividend returns are real returns and it was an excellent year for the stock market.
