CV = st dev/ (x)

I agree, D: CV = st dev / (x) .5 = st dev / (x) .5x = st dev

Lets see… standard deviation is the square root of the variance: Variance= the squared difference of every single observation from its mean (in this case return) divided by the number of observation. D

yes its D. But why is everyone dogging the first one. I could not do the dollar weighted part. i need your help guys come on.

forgot how to do first part, doing quant all day so I should be able to do it later.

Dollar weighted return= IRR use calculator Time weighted return= Geometric mean
