Hewitt: Thanks for the post. I think it's a useful approach. I was curious though: Mathematically, you can derive the equation ER = (1-PIV)/PIV. IE: for Walmart PIV=48/71=0.676. ER=(1-0.676)/.676=0.479 So what? Well if your portfolio has a PIV of 0.52, it's ER must = (1-0.52)/0.52 = 0.923 or 92.3% not 128%. Did I miss something here? All the best, Zee |
