What is the S&P 500?
The Standard & Poor’s 500, commonly known as the S&P 500, is a stock market index that measures the performance of 500 of the largest publicly traded companies in the United States. Established in 1957, the S&P 500 serves as a barometer for the overall health of the U.S. economy and is one of the most widely followed equity indices in the world.
“The S&P 500 is not just an index; it’s a reflection of the American economy.”
The S&P 500 includes companies from various sectors, such as technology, healthcare, finance, and consumer goods, making it a diverse representation of the U.S. economy. Notable companies included in the index are Apple, Microsoft, Amazon, and Google’s parent company, Alphabet.
Investors often use the S&P 500 as a benchmark to compare the performance of their own investment portfolios, making it an essential tool for both novice and experienced investors alike.
How is the S&P 500 Constructed?
The S&P 500 is a market-capitalization-weighted index, meaning that companies with larger market capitalizations have a more significant impact on the index’s performance. The market capitalization is calculated by multiplying the company’s stock price by the total number of outstanding shares.
Market-Cap Breakdown
