Stocks are weighted by their available market capitalization, which is calculated by multiplying the composite closing price by the available shares. Available Shares Available shares are assumed to be shares available for trading. Other sources are used in cases of missing or questionable data. When shares of a company in the index are held by another company also in the index, this is considered corporate cross-ownership. Any percentage held in this class will be adjusted.
Composite prices are the last trade price on any U.S. exchange.

Dividends Gross dividends are included in the daily total return calculation of the Indexes based on their ex-dates. Monthly, quarterly, and annual total returns are calculated by compounding the reinvestment of dividends daily. Thus, the number of securities in the indexes over the year will fluctuate according to corporate activity. When a stock is acquired, delisted, or moves to the pink sheets or bulletin boards on the floor of the Stock Exchange, the stock is deleted from the index at the close on the effective date or when the stock is no longer trading on the exchange.
