Too much diversification is the Noah's Ark approach. End up with two of everything and returns in the bell curve at best. IF you adhere to strict position sizing relative to the capital in the account, say 1% and.........IF you're willing to hold positions overnight swing trading (as opposed to daytrading), and unintended by-product is some diversification. Ditto for riding your winners. Swinging for the fences with a concentrated position or two works ............until it doesn't. Then come on here and whine about it. Blaming everyone but themselves. Scapegoats with a broadbrush generic word such as manipulation. This is a rigged game. Doesn't mean it can't be beat, but is rigged. In a variety of ways. The previously cited gap being just one. Unmanagable position sizes, paritucularly in llliquid instruments is "asking for it". Hurt me hurt me. We could delve into psychology such as greed being a denial of risk or masochistic tendicies, but it's too much typing. There's nothing wrong with a little diversification. As a bone us, it might acutally satisfy your craving for action.
