The S&P 500 Indexadmin 18 July 2021
what you read here:
The S&P 500 index, which stands for the Standard & Poor’s 500 Index, tracks the stocks of 500 large-cap U.S. companies. This index represents the stock market’s performance by highlighting the returns and risks of these large 500 companies. S&P 500 accounts for 80% of market value, which is why it is the best single gauge of the market.
This index is weighted by market capitalization, and the value of each company has a unique influence on the index performance. So, the listed companies do not represent 1/500th of the index. Some large companies such as Apple and Microsoft have a more significant effect on the index than smaller ones. Although the companies in the list are almost the top 500 American companies based on their value, the market cap of some big companies is more than 1 trillion dollars, which is 200 times larger than the small companies in this index.
The S&P 500 is a member of the S&P 1200 indices group. S&P 400 MidCap includes mid-cap range companies, and the S&P SmallCap 600, contains smaller companies. A combination of S&P 500, S&P MidCap 400 and S&P SmallCap 600 create the S&P 1500 Composite representing the U.S. all-cap index.
This index was introduced by the Standard and poor company in 1923. The founder of this company was Henry Varnum Poor, who could establish the company earlier in 1860. In the beginning, the number of stocks that were tracked by this index was so low. Gradually they could expand their activities and cover more stocks. After years of hard work and gaining investors’ trust, in 1957, they could increase the number of companies to 500. In the same year, they changed the name of this index from the “composite index” to the “S&P 500 index”.

There are 505 stocks in this index which 500 companies issue them. Some of the companies, such as Alphabet, issued more than one type of stock. This explains why the number of stocks is more than the number of companies.

Market capitalization is calculated by multiplying the number of shares by the market price of one share of a company. S&P only considers publicly traded shares for calculations. To calculate the S&P 500 index, first, we should calculate the market capitalization of each company. The sum of all of these 500 market capitals equals the total market capitalization of the entire index. The value of the index is calculated by dividing the market cap of each company with a particular divisor that is not publicly available.
S&P 500 vs Other Stock Market Indexes
Although the Dow Jones includes 30 of the largest U.S. companies, the S&P has more large-cap stocks. The Dow Jones index market capitalization accounts for one-fourth of the U.S. stock market. Dow Jones is also the most quoted market indicator in the U.S., but the S&P 500 is more accurate than Dow. Compared to Nasdaq, S&P 500 tracks fewer technology-related stocks. In 2020, about 57% of Nasdaq index stocks were related to technology. However, this figure was about 23% for S&P 500 at the same time. These indexes have many differences, but they all move together. If you only focus on one of them, you can easily guess the situation of other indexes.
