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. The Törnqvist or Törnqvist-Theil index is the geometric average of the n price relatives of the current to base period prices (for n goods) weighted by the arithmetic average of the value shares for the two periods. 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. A stock trading at $100 will thus be making up 10 times more of the total index compared to a stock trading at $10.

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.

There are issues with how stock indexes are calculated that can lead to disadvantages. For example, the DJIA is a price-weighted index. The index is calculated by taking the sum of the prices of all 30 stocks in the index. This sum is then divided by a divisor.

Over time, price weighted stock indices are adjusted for stock splits and other changes in the index constitution (the divisor of the index changes accordingly). S&P 500 Composite Stock Price Index.
