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 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 capitalizationMarket CapitalizationMarket Capitalization (Market Cap) is the most recent market value of a company’s outstanding shares. 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. You’ll often find a company or person owns a large amount of the outstanding shares with no plan to sell. For example, company XYZ has 20 million outstanding shares but another company owns 5 million (25% of the shares). In this case, a float adjusted, cap weighted index will only use 75% of XYZ’s market cap to figure out its place in the index. The capitalization-weighted index would place 25% of the total portfolio in the undervalued stock and 75% of the total portfolio in the overvalued stock. The equal-weighted index requires that an investor place the same amount in each stock in his or her portfolio. In other words, each stock would comprise 50% In other words, the stocks with the higher prices will have more impact on the movement of the index than stocks with lower prices, since their price is "weighted" higher. For example, if a stock goes from \$100 to \$110, it will move the index more than a stock that goes from \$20 to \$30, even though Now to get the weights for each company, first add up the market capitalization for each company to get the total. Then take each company's market capitalization and divide it by the total to get its weight. For example, Company A's weight = \$100,000,000 / \$235,000,000 = 43%.

For example, typically in bear markets, the cap weighted index may outperform (even though both may be declining) the equal weighted index. This may be because of the lower small company weighting. For example, let's assume that the following companies are in the XYZ price-weighted index: A price-weighted index is simply the sum of the members' stock prices divided by the number of members. Thus, in our example, the XYZ index is: \$5 + \$7 + \$10 + \$20 + \$1 = \$43 / 5 = 8.6.
