Weighted is a description of adjustments to a figure to reflect different proportions or "weights" of components that make up that figure. A weighted average, for example, takes into account the proportional relevance of each component instead of measuring each individual component equally. The Dow Jones Industrial Average (DJIA) is a price-weighted average that compares each security based on the stock's price relative to the sum of all the stocks' prices. The S&P 500 Index and Nasdaq Composite Index, on the other hand, are based on market capitalization, where each company is measured relative to its market value.
