About the S&P 500
The S&P 500 tracks around 500 of the largest US-listed companies and is the benchmark most people mean when they say “the US stock market.” Because it is weighted by market value, the biggest technology names carry outsized influence, so the index often moves with the fortunes of a handful of mega-caps. It reacts to Federal Reserve policy, inflation and jobs data, corporate earnings season and the overall risk mood.
What's inside it
The S&P 500 is made up of 500 companies (Apple, Microsoft, NVIDIA, Amazon, Alphabet, Meta and the rest of the large-cap US market), combined using a free-float market-cap weighted method and quoted in USD. Membership and weights are reviewed periodically by the index provider, so the exact line-up shifts over time.
