Please refrain from commenting that the gains possibly weren't audited, that CANSLIM/momo swing trading doesnt work,that your trading system is far better blah blah blah.
lol and yet what you asked not to happen is exactly what did happen. It is what must happen, apparently, here at ET, where the name is "elitetrader" and yet there is no real discussion of trading anywhere to be found except more than a decade ago in the cobwebs.
My question is, is it more likely that guys like him are far exceeding 1% and going closer to a kelly,half kelly,optimal f etc. to attain these gains? Anything im missing?
In Momentum Masters, Zanger said he usually limits exposure per position to 10% of his equity and uses a 2-3% stop on each position. However, he bases his position size on the market (is it a strong bull or average?) and the strength of the stock in terms of price action as well as sales and earnings growth. On a strong stock he says he might have as much as 20% of his equity invested. When Google was first issued and broke out of its first base, he had 50% of his trading capital invested in that one stock.
I'm not sure Zanger is a Kelly guy in terms of be aware of and using the formula. He does, however, seem to have an intuitive sense of optimal position sizing based on stock selection and other criteria he uses.
