Meanreversion, I'm sure you know more about hedge funds than I do, as you have alluded to it a few times. There's one thing I know about, which is something obvious. Those firms manage millions and even billions of OPM. They are forced to be over-conservative. The inidividuals that trade the hedge funds I'm sure could make a lot more on thier personal accounts. The traders of the hedge funds have a million to billion dollar industry to protect. In getting the gains I get, I just have my personal assets to look out for, and I have an equi-amount of liquid assets outside my trading equity as a backup plan. There is a big difference in discussing individual trading as opposed to huge hedge funds.
Warren Buffet is another good example. He makes millions on one trade, but he has billlions in equity in his account. All he needs to do is palce his trade with miniscule margining, walk away, and then come back when he is 100-200 pips up, regardless how long it might take. We could trade the same way Buffet does but it would amount to punity if we did, because of the lack of funds we have by comparison.
