I think the flaw in my trading is my money management. I believe I allocate far too much into one stock. I understand position sizing but I always end up having my funds in 2-3 stocks at a time. I'll pick 1-2 stocks from a few sectors I like and swing trade them over a few weeks and intraday press them. Sometimes I hold margin overnight, but most of the time I only go out on margin intraday...I feel more comfortable trading a few stocks at a time, sometimes in pairs, because I think it's easier to follow them while working a finance job... What are folks thoughts on this subject? Do you think having 33% of your trading account in one stock is nuts? What's the Max % you'll go? I'm using stops and calculating my risk rewards, but perhaps I should be taking shots at 5 or 6 stocks at a time instead of 2 or 3... Why am I asking this? Well I got smoked by a SEMI and Biotech today while the rest of the market did well...I'm annoyed about that and the fact that I keep having these wild swings daily. I can get up 30% fairly quickly, but I can give back 10% almost as fast... Am I too agressive?
