An index number is a percentage value designed to measure the over all change in a variable, or in a group of related variables, by reference to a base value. In other words it is a number that measures the change in a variable over time. For example an index number is used to measure changes in national income, 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. Market-value weighted index: This kind of index tracks the proportion of a stock based on its market capitalization (or market value, also called market cap).Say that in your portfolio, you have 10 million shares of a $20 stock (Stock A) and 1 million shares of a $40 stock (Stock B). Stock A’s market cap is $200 million, while Stock B’s market cap is $40 million. Data and Calculation. Go to the BLS website to find data on the value of the index at the particular times you want to measure.

Specifically, the fair value is the theoretical calculation of how a futures stock index contract should be valued considering the current index value, dividends paid on stocks in the index, days 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.

Calculating a profitability index The next step is to use the information from the net present value calculation to determine a profitability index for the investment. The profitability index is A price-weighted index is often criticized because it considers only the price of each component as the driver of the index value. Therefore, even a small price fluctuation in a higher priced company may significantly affect the value of the index. How to Calculate the Weights in a Price-Weighted Index In this example, subtract the starting index value of $100 from the ending value of $110 to find it went up by $10. Divide the gain or loss by the initial value to figure the rate of return for the index. Continuing the example, divide $10 by $100 to get a return rate of 0.1.
