The S&P 500 represents the industry standard for large-cap indices. While the Dow Jones Industrial Average (DJIA) may be the most visible stock market index in the country, the S&P 500 has long been relied on by industry insiders and fund managers as the more reliable gauge of portfolio performance.

While the DJIA is price-weighted and only includes 30 stocks, the S&P 500 uses a weighting system that factors in market cap and the size of a company’s free float while including some 500 stocks for a more comprehensive look at the broader markets’ performance. Its performance is far more representative of the large- and mega-cap stocks for any period of time.
