Introduction

The S&P 500, often referred to as the Standard & Poor's 500, is a stock market index that tracks the performance of 500 of the largest publicly traded companies in the United States. It's a key indicator of the overall health of the U.S. economy and a benchmark for the performance of the stock market.

This guide delves into what the S&P 500 is, why it's important, how it works, and how investors can use it to make informed decisions. We'll explore its composition, calculation, and significance in the world of finance.

What & Why (context, benefits, risks)

The S&P 500 is more than just a list of 500 companies; it's a carefully constructed index designed to represent the U.S. stock market accurately. It is a market-capitalization-weighted index. This means that each company's influence on the index's performance is proportional to its market capitalization (the total value of its outstanding shares). Larger companies, with higher market caps, have a more significant impact on the index's movements. — North New Hyde Park, NY: Your Complete Guide
