Very true blood burner. Like in real life, higher risk can bring higher reward. Not sure I'd want to put all my real life money into so few shares though.l
I am sure rules have been debated - and maybe the way you have it is best. I would be interested to see what the portfolios would be if you where not allowed to spend more than 20% of your total holdings on 1 share. I very quickly fell into the hold one share for big gains bucket - not that it worked for me, I'll be happy now just finishing in the 100's and getting out the 200's.
But then we might debate a person buying 5 junior coal miners and if that was realistic for an investment club - there will always be something!
Have found it very interesting - esp the way the ETF's perform. And kudo's on the programming - I am sure you command top dollar!
