The weight function ():= corresponds to the unweighted situation in which all elements have equal weight. One can then apply this weight to various concepts. If the function : is a real-valued function, then the unweighted sum of on is defined as

Adjustment Factor = Index specific constant "Z" / (Number of shares of the stock * Adjusted stock market value before rebalancing) A stock trading at $100 will thus be making up 10 times more of the total index compared to a stock trading at $10. The Dow Jones Industrial Average and Nikkei 225 are examples of price-weighted stock market indexes.
