SWASH

C: an equal-weighted index : An equal wtd index will have bias towards small cap stocks because if the index, say, has 10 stocks each stock will have a wt of 10%. in this case say the first two companies are very big ( 1000 bn each) as compared to other 8 stocks (50 bn each) in the index, but since eqally wtd, all will have 10%. If you are PF manager you have to take 10% exposure in each stock ( 2 large-20% and 8 small -80%). Effectively your portfolio is predominantly in small cap stocks.
The concern is to avoid this. Hence “C” does not address his concern. Hope this is clear.
