What is the S&P 500?

S&P 500 Index Bullish

The S&P 500 (Standard & Poor's) is the biggest index in the United States that indicates the performance of the top 500 large-cap stocks listed on NYSE or NASDAQ. S&P 500 holds $42.368 trillion market capitalization, which is more than 75% of the total total U.S. stock market capitalization comprising 11 different leading sectors. (Update: 04/01/2022)

All the 500 Companies are selected by the U.S. Index Committee based on many factors like - Market Cap, Revenue, Liquidity, Sector, Shares in the Public, Performance, Location, and Annual Trade Value, etc. For that reason, the S&P 500 is the face of the entire American market which the investor use as a benchmark so that they can compare other investment instruments at a standard level.

How the S&P 500 Works?

The Standard & Poor's 500 work on the weighted market capitalization method which means that a company with a high market cap has a high ranking in the index. The calculation of companies' weightage is very simple, taking each company's market cap and dividing it by the total market cap of the S&P 500 index. 

S&P 500 Weightage Formula

[Note: In the S&P, Company's free float market cap is used to calculate the weight, which means only those shares are taken which are available for public trade, other shares are not included.]

Company Market Cap = Current Market Price of Stock x Company's Outstanding 

Total Market Cap of Index = Add The Market Cap of Each Company in The Index

For example, Apple has a market cap of $2.998 trillion (04 Jan 2022), while the total market cap of the S&P 500 is $42.368 trillion (estimated), so the weighting of Apple stock is 7.06 in the index.

Companies with a large market cap in the index get more weightage compared to small market cap companies. As a fact, the technology sector in S&P 500 has more than 29.2% of weightage which means this industry has more influence on the index.

Also, stock weight is valuable data for investors because they can understand the importance of each stock and divide their portfolios based on stock weight to get good returns with low risk. Check this document for in-depth details about S&P Indices Methodology

S&P 500 vs. Other Index

The Standard & Poors index represents the top 500 large-cap stocks based on weighed market capitalization but the Dow Jones Industrial Average (DJIA) also known as the Dow 30 Stocks is focused on thirty blue chip publicly traded stocks which are price-weighted.

The value of the Dow reflecting the sum of the share price of the 30 stocks adjusted by dividend or stock split and all companies ranking changes on their importance, whereas S&P consists of stocks selected by committee only.

The S&P has all types of sector stock which is not considered in Nasdaq Index because Nasdaq-100 works on the updated market cap method which includes 100 non-financial large-cap companies which are listed on the Nasdaq Stock Exchange.
