The S&P 500 stock index is claimed to be the best single gauge of overall stock market performance in the United States by owners McGraw Hill Financial, according to its website. The S&P 500 is estimated to capture approximately 80 percent of the available market capitalization in stocks as of 2015. The 500 individual companies comprising this index are selected from 10 sectors of the economy, with the largest portions of the index comprising information technology, financial and health care companies.
Because the S&P 500 is a composite measure of stock price across many companies, the performance of any given component of the S&P 500 may not match the index's overall valuation. While investment strategies such as the Vanguard S&P 500 index fund try to focus on matching overall returns, investors wishing to maximize their returns can benefit from examining the performance of individual component stocks, explains The Vanguard Group. This allows these investors to fine-tune their holdings or exploit opportunities specific to one stock in the index.Learn more about Investing
