To calculate the value of a value-weighted index, sum the market capitalization for each company and divide it by a divisor which is set initially to make the index a round number. To unlock this 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 stock trades at $90 per share and Company's B's stock trades at $30 per share, Company A's stock is weighted three times as heavily as Company B's.

## Calculation of a Capitalization-Weighted Index. Company A: 1 million shares outstanding, the current price per share equals $45. Company B: 300,000 shares outstanding, the current price per share equals $125. Company C: 500,000 shares outstanding, the current price per share equals $60. Company D:

To calculate the value of a simple price-weighted index, find the sum of the share prices of the individual companies and divide by the number of companies. In some averages, this divisor is adjusted in order to maintain continuity in the event of stock splits or changes to the list of companies included in the index. Divide 365 by the number of days between the calculated price-weighted indices. This calculates the fraction of a year between values. In the example, there are 12 days between the calculated index values, so you divide 365 by 12 to get 30.42. 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, The change in an index’s value from one point in time to the next represents the performance of the index (i.e., the performance of the market/segment it is designed to measure). Calculating index values. Below is a hypothetical market cap-weighted index that includes five constituents. Price-Weighted Index Formula Price-weighted index formula is represented as follows, PWI Formula = Sum of Members Stock Price in index / Number of members in the Index. Weight (i) = Price of Stock (i) / Sum of all the Members Prices. A Value Weighted Index weights stocks within the relevant universe based on a calculation of each stock's absolute and relative value as compared to the other stocks within the index universe. The index is continually rebalanced to weight most heavily those stocks that are priced at the largest discount to various measures of value.

### Quarterly and annual frequency index returns are calculated by compounding monthly index returns. CRSP Market Indexes. An Equal-Weighted Index and a Value

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. There are two main techniques for calculating a stock market index. A price-weighted index gives value in the index to the stocks based on the share prices. The Dow Jones Industrial Average is a price-weighted index.

### If your index is equally weighted, you started out with the same dollar amount in each stock. Therefore, you can simply add up the percentages and that is your total return. In the example, you would have plus 10 percent, minus 5 percent and plus 3 percent. Your total return would be 8 percent.

## 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. Why Does a Price-Weighted Index Matter?

computed by calculating a weighted average of the returns on each security in the index, where the weights are proportional to outstanding market value.
