Indices are the hypothetical portfolio of asset class, securities, and market segments that are used to determine how the market is performing. Now there are several ways (Market-Capitalization Weighting, Price Weighting, Equal Weights) to calculate and form the index.
If the index is weighted by Price (Price Weightage), the highest-priced assets will have a greater influence on the index than those with lower values. This method of calculation is followed by Dow Jones Industrial Average
And,
In Market-Capitalization Weightage, changes in the prices of stocks with a large market capitalization have an impact on the component stocks of indexes. This method is more common against the price weightage method across U.S. indices. S&P 500 uses this technique giving companies with the greatest market capitalizations a larger percentage allocation.
Top US indices
There are nearly 3.3 million stock market indices around the world, according to new research from the Index Industry Association (IIA) out of which there are 5000 indices only in the US which comprises the US equity market.
Among those 5000 3 top Indices are widely followed and give a clear idea of how US markets are performing:

S&P 500
The S&P 500 is one of the top three indices, introduced in 1957 to track the value of 500 corporations listed on the New York Stock Exchange (NYSE). It began tracking 90 stocks in 1926 and expanded to 500 in 1957.
It comprises firms from 11 different industries with no more than 30% of the total budget given to a single sector and Technology having the biggest bite of the pie with 28% and Healthcare with 14%
When compared to Dow Jones (30 stocks), S&P is believed to be a truer picture of the broader market because it is meant to convey the entire composition of the US economy.
For a company to get listed in S&P 500 it must have:
- $8.2B market cap.
- Stocks must be highly liquid (stock that is easily sold, because there is a large volume of shares traded every day)
- Public float of 50%+ shares
- Positive earnings
- It should be a US company.
- 12 months since IPO.
