What is the S&P 500?

The Standard & Poor’s 500, more commonly referred to as the S&P 500, is an index of the 500 largest publicly traded stocks in the United States. Representing approximately 80% of the total U.S. stock market capitalization, the S&P 500 is a reliable indicator of the U.S. stock markets as a whole.

Started in 1923, the S&P 500 is one of the oldest, most-followed indexes in the world. It includes stocks from eleven major corporate sectors, including basic materials, communications services, consumer discretionary, consumer staples, energy, financials, healthcare, industrials, real estate, technology, and utilities. The components of the S&P 500 are widely watched and widely traded, offering investors exposure to many of the largest and most influential companies in the U.S.

The index itself is calculated by Standard & Poor’s, a subsidiary of the S&P Global. The index is calculated using a weighted average of the prices of each of the stocks in the index, which is based on their respective market capitalization. As with any weighted average, stocks with larger market capitalizations are more heavily weighted than those with smaller market capitalizations.

How Is The S&P 500 Used?

The S&P 500 is used as an overall barometer for the U.S. equity market. It is also used as a benchmark to judge the performance of active stock market investors. Investors who are benchmarked against the S&P 500 are looking to beat the index’s return, which can make a portfolio look more attractive to potential clients if it can outperform the benchmark.

The S&P 500 is also used by many mutual funds and ETFs as a benchmark. Many mutual funds will directly invest in the S&P 500 stocks in order to match the performance of the index, while ETFs will invest in a basket of securities which track the S&P 500.

How Can You Invest In The S&P 500?

The S&P 500 can be bought and sold through mutual funds, ETFs, and brokerage accounts. It is important to do some research before investing in any of these securities to make sure you are investing in a fund with low fees, a good strategy, and a well-diversified portfolio.

For the average investor, the most cost effective way to invest in the S&P 500 is through an ETF. ETFs are passively managed, meaning they track the S&P 500 but do not actively trade stocks. This lowers expenses and makes buying and selling easier.

Conclusion

The S&P 500 is one of the most widely-followed equity indices in the world and is used by many active investors as a benchmark to judge their performance. Investors can take advantage of the S&P 500 by investing in mutual funds or ETFs that track the index, which is a cost-effective and simple way of gaining exposure to the U.S. markets.
