Market capitalisation weighted index calculation

The Capitalization-Weighted Index (cap-weighted index, CWI) is a type of stock market index in which each component of the index is weighted relative to its total market capitalization. In a capitalization-weighted index, companies with larger market capitalization exert a greater impact on the index value. Calculating a market-capitalization-weighted index involves first calculating the market cap of each stock in the index. Market capitalization is the stock price times the number of stocks outstanding, and it represents the market value of the company. Capitalization-weighted Index (also called cap-weighted or value-weighted index) is a capital market index in which the constituent securities are weighted based on their market capitalization, which equals the product of its price per share and total number of common shares outstanding. The weight of each security is calculated by the ratio of its market capitalization to the sum of market capitalization of all constituent securities.

The individual market weights are calculated by dividing the free-float market capitalization of a company in the index by the total market capitalization of the index. As of January 2019, the S&P 500 total market cap was approximately $23 trillion. This market cap Apple roughly a 3% market weight. A price-weighted index is a stock index in which each company included in the index makes up a fraction of the total index proportional to that company's share stock price per share. In its The S&P 500 Index or the Standard & Poor's 500 Index is a market-capitalization-weighted index of the 500 largest U.S. publicly traded companies. The index is widely regarded as the best gauge of In a capitalization-weighted index, each component stock contributes its market value to determine the overall index value and, therefore, stocks with greater market value are given more weight in this type of index. Calculating the Index Value. The market value of each stock can be calculated by multiplying the stock price with the total number of shares outstanding. The sum of the market value of all the component stocks is then divided by a divisor to obtain the final index value. The market-cap-weighted index, as the name implies, weights companies according to market cap. Here, Company A has a market capitalization of $6 billion which is equal to 60% of the total market cap of all stocks ($10 billion). However, the main risk that comes with market-capitalization weighted index tracking is worth noting. The risk is that if a stock, sector or even market becomes overvalued, then it naturally becomes a larger portion of the index, when market capitalization weighting is used.

Value weighted index calculation. The weights of individual stocks in a value weighted equity index are proportional to their market capitalization. For example, shares in a company with market cap of 50 billion dollars will have two times greater weight in the stock index than shares in a company whose market capitalization is 25 billion. In market cap-weighted indexes, a company’s representation within the index is based on its size, and its performance contributes to the performance of the overall index proportionately. In other words, the company with the largest market cap will represent the largest weight in the index, meaning mega cap companies like Apple will impact the performance of the overall index more than a small cap company will.

Capitalization-weighted index: You must have an historical database of the number of shares outstanding or the market capitalization of the index stock components. Equal-weighted index or Price-weighted index: This type of index gives the same weight to each stock in the index or composite. Small and large companies will have the same importance in the index price. Differences in how index values are calculated can occur depending on the index weighting scheme. For the sake of simplicity, we will explain the calculation of market cap-weighted index values. As prices and market values of the stocks within an index rise and fall, the index reflects this movement using a series of index values.

A capitalization-weighted (or "cap-weighted") index, also called a market-value-weighted index is a stock market index whose components are weighted according to the total market value of their outstanding shares. Every day an individual stock's price changes and thereby changes a stock index's value.
