| tijean25 | Where are the returns on this? I need someone to show how to get to that result |
| enetis | kinda confused here. thought geometric mean does'nt work for negative returns |
| praj24 | @enetis - if you look at the formula, you're adding 1 to the return. e.g -5.9%, therefore it'll be 1-0.059 = 0.941 ((1.023)(0.941)(1.032)(1.075)(0.989)(0.984))^1/6 - 1 *100 = 0.64% |
| Rohule | im confused since its montly returns and ther formula noes not need exponetial, i thought that was only for anual returns |
