It also shows the CAGR (compounded average growth rate) of the index. The CAGR is the average rate at which the index would have grown every year to reach where it is now.
For example, let’s say the index was at 100 in the base year. Let’s say the CAGR is 10%. This would imply the index was at 100*10%, which is 110. Similarly, in the second year, the index would be at 110*10%, which is 121, and so on. Remember, the index actually would vary from year to year, but the CAGR shows the average rate at which the index grew each year.
The graph proves that the S&P 500 will not only keep up with inflation but also gives returns that are much higher than inflation rates. There is volatility (VXX)(XIV) among returns each year. However, the CAGR on the index since 1975 is 8.9%, which is better than the inflation rates in most years.
