Traditionally, capitalization- or share-weighted indices all had a full weighting i.e. all outstanding shares were included. Recently, many of them have changed to a float-adjusted weighting which helps indexing.A modified market cap weighted index is a hybrid between equal weighting and capitalization weighting. It is similar to a general market cap with one main difference: the largest stocks are capped to a percent of the weight of the total stock index and the excess weight will be redistributed equally amongst the stocks under that cap. Moreover, in 2005, Standard & Poor's introduced the S&P Pure Growth Style Index and S&P Pure Value Style Index which was attribute weighted. That is, a stock's weight in the index is decided by the score it gets relative to the value attributes that define the criteria of a specific index, the same measure used to select the stocks in the first place. For these two stocks, a score is calculated for every stock, be it their growth score or the value score (a stock cant be both) and accordingly they are weighted for the index.
