How about for stocks? How are you coming up with a position size for your portfolio? I use the percentage of my portfolio that I'm willing to risk. I take the difference between my entry and my stop and divide that into the percentage of my portfolio I'm willing to risk to come up with the number of shares I will buy. If my account size is 25k and I'm willing to risk 1% then the amount of risk is $250. If my entry price is $25 and my stop is 23.60 then my risk is $1.40 $250/$1.40 = 178.57 which I would round down to 170 or even 150 shares to allow for a little slippage. Using this method you end up with a portfolio of 6 or 7 stocks. If you feel that this is not enough diversification reduce the percentage risk.
