What is the S&P 500?

Asked 6 months ago
The S&P 500 is a stock market index composed of 500 large publicly traded companies listed on US stock exchanges. It is a measure of the performance of the US stock market, representing a broad cross-section of industries and sectors. The index is widely used as a benchmark for evaluating the overall health of the stock market and is considered one of the best indicators of the US economy's strength. The companies within the S&P 500 are selected based on certain criteria including market capitalization, liquidity, and sector representation. The index is weighted by market capitalization, meaning that larger companies have a greater impact on its performance. The S&P 500 serves as a key tool for investors, analysts, and economists to gauge market trends and make informed investment decisions.
