Weighting

In the FTSE, share prices are weighted by market capitalisation, so that the larger companies make more of a difference to the index than smaller companies. The basic formula for any index is (be it capitalization weighted or any other stock index):
  • Index level= Σ(Price of stock x Number of shares) x Free float Adjustment factor / Index Divisor.


The Free float Adjustment factor represents the percentage of all issued shares that are readily available for trading. The factor is then rounded up to the nearest multiple of 5% for calculation purposes. To find the free-float capitalisation of a company, first find its market cap (number of shares x share price) then multiply by its free-float factor. Free-float capitalisation, therefore, does not include restricted stocks, such as those held by company insiders.
