Patrick,
I seem to think that there is an error with your percentage calculations on the shares page. Just looking at lament's portfolio, his overall percentage is higher than any of the 2 individual shares he has - technically this is not possible. The overall page's percentage looks right to me. Am I missing something?

Sounds logical doesn't it! Fortunately my maths defeats your english  8)

While what you're saying appears to make sense, you need to remember that all the shares weren't bought at once. So if he bought more of a share that was doing well in month 2 of the competition (woolworths in his case), his average cost of that share would have gone up, and his percentage growth on that share gone down. But with the share continuing to rise he would have made more money than if he didn't average up.

I did just this yesterday in reality buying CML in the mid R57 range while my previous purchase was at R47. My percentage gained on CML now looks lower, but my portfolio gain is up in rand terms, and that's where it counts.

Here's the maths for lament:
(562 932.54 - 500 000)/500 000 * 100.

I'll send you a bill for the extra lessons  ;)

Edit:
Ok after all that and I did find a calc error. The % gain on the per share level was underestimating by a small amount. Fortunately that figure isn't used anywhere. It's been fixed, school fees will be refunded  :o

What happened to that guy in 1'st place doing 19%? He has just disappeared like in a flash. Was i not SaiyanZ? Now sitting near the bottom with JaDEB?
Would love to know the stock that led to his downfall.
