Definition
Weighted average market capitalization refers to a method of constructing a stock market index whereby each component stock is weighted according to its total market capitalization. This means that larger companies have a greater influence on the performance of the index compared to their smaller counterparts. Essentially, you can think of it as the stock market putting its thumb on the scales to favor the big players!
