## Value weighted index divisor

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.

In reality, the value of a price-weighted index is calculated by dividing the total sum of the prices of the index components by the divisor. The divisor is an arbitrary value computed by the index and adjusted for various structural changes in the index components. For example, Assume the market index price is \$10,000. Calculate the base divisor. Divide the market cap by the market index price for the current base divisor. For instance, if the current market cap is \$100 million and market price of the index is \$10,000, the base divisor is also \$10,000. Market capitalization is the market price of a security time the number of shares outstanding. To calculate the value of a value-weighted index, sum the market capitalization for each company and The value of the components of a market-cap-weighted index can be very large. At the time of publication, the value of the stocks tracked by the S&P 500 was \$12.7 trillion. The divisor used to calculate the S&P 500 brings that very large number down to the current value of around 1400. The index divisor is an arbitrary number that is first defined when an index is first published. It's initial use is to divide the total value of the index to produce an initial index value that is a number which is easy to handle, such as the number '100'. The entire market value of the index components equals \$232.5 million with the following weightings for each company: Company A has a weight of 19.4% (\$45,000,000 / \$232.5 million) Company B has a weight of 16.1% (\$37,500,000 / \$232.5 million) Company C has a weight of 12.9%

## A price-weighted index gives influence to each of the companies in the index based on its share price, not its total market value. For example, if Company A's

index's intended exposure; Weighting: How index components are weighted relative to one another; Calculation: How index values and returns are generated   A stock index which is computed by adding the capitalization (float times price) of each individual stock in the index, and then dividing by the divisor. The stocks  Most stock market indexes, for instance, are weighted by market capitalization, In order to keep the average the same, the divisor must be changed so that the  the value of the divisor in the second period (t = 2). A) The price- weighted index at time 0 is (70 + 85 + 105)/3 = 86.67.

### 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.

Unlike in a capitalization-weighted index, the divisor of a price-weighted index does not need to be changed when a component stock issues additional stock via a  The Dow Jones Industrial Average is a price-weighted index. A market-cap- weighted index totals the market value -- share price times shares outstanding -- of the  In reality, the value of a price-weighted index is calculated by dividing the total sum of the prices of the index components by the divisor. The divisor is an  The total market value of every stock in the index is \$970, so Stock A's weight, index divisor by dividing the total market value of the index by the base index  17 Jul 2000 The formal formula to calculate a cap weighted index value, such as the S&P 500 index value, is: Index Value = 1/divisor * SUM ( Price(i)  The NASDAQ Composite Index is a market capitalization-weighted index. ( Market Value after Adjustments/Market Value before Adjustments) X Divisor before. Total dividends and divisor adjusted dividends for index futures. [Floating Capitalization Weighted: stock price and per-share dividend are multiplied by the

## 4 May 2017 For a price weighted index like the Dow this means a new divisor split the divisor is 2 to take a simple average creating the index value of 10;

Assume the market index price is \$10,000. Calculate the base divisor. Divide the market cap by the market index price for the current base divisor. For instance, if the current market cap is \$100 million and market price of the index is \$10,000, the base divisor is also \$10,000. Market capitalization is the market price of a security time the number of shares outstanding. To calculate the value of a value-weighted index, sum the market capitalization for each company and The value of the components of a market-cap-weighted index can be very large. At the time of publication, the value of the stocks tracked by the S&P 500 was \$12.7 trillion. The divisor used to calculate the S&P 500 brings that very large number down to the current value of around 1400.

In the case of a value-weighted index, the amount of outstanding shares comes into play. To determine the weight of each stock  An index divisor is a number chosen at the inception of the index which is applied to the index to create a more manageable index value. When an index is created, be it a price or market cap weighted index, the prices of the index constituents are added together to create the initial starting value of the index.
