DJIA is a pretty bad index. S&P 500 or an even broader market index performs much better. "Although it is one of the most commonly followed equity indices, since it only includes 30 companies and is not weighted by market capitalization and is not a weighted arithmetic mean,[citation needed] many consider the Dow to not be a good representation of the U.S. stock market and consider the S&P 500 Index, which also includes the 30 components of the Dow, to be a better representation of the U.S. stock market." - https://en.wikipedia.org/wiki/Dow_Jones_Industrial_Average https://en.wikipedia.org/wiki/Dow_Jones_Industrial_Average
