I get where you’re coming from. Trading other people’s money and getting a percentage of the gains (…and not sharing the losses) is the best scenario that a trader could be in. If you can trade 10x your personal account size using OPM while keeping 20% of the gains for yourself it would double the rate of return on your funds. The only problem is market volume. When the AUM gets large enough some of yours strategies may not be possible due to volume. You’d have to spread it out over additional trades and that will likely drop your performance.
Ty, Yes, I think that's a really major understated issue. I almost feel fortunate not to trade OPM in light of this. Volume quickly becomes an issue. There's also, for me, an extra weight or responsibility trading OPM, perhaps like driving someone else's car, I don't feel OK about taking risks that are valid but that fall outside normal business limits.
