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.
