On The Difference In Returns Between S&P 500 Price and Total Return Index

The S&P 500 Index that is benchmark of US equities is a price index – meaning dividends are not included in the return calculations. Since this index is the most popular and reported by the media all the time, investors may use this index to compare their portfolio performance. This is not the correct way to benchmark one’s portfolio return against an index. Assuming an investor reinvests dividends the better way to measure the performance of US stocks is to use the S&P 500 Total Return Index which includes dividends reinvested.

Of the 500 companies in the index, 425 paid dividends at the end of 2015, So when these dividends are reinvested the return will be higher over the long-term due to the effect of compounding. The difference between the S&P 500 Price Index and Total Return can be substantial over many years such as 5 years as shown in the chart below:
