Sure, but you didn't ask about ROI now did you. Max out your leverage at a prop firm (offering 50 to 1 or more), and your ROI skyrockets. Then again, not everyone has such an opportunity, so the answer to the question, "How much can you make?" differs for each person (using ROI as the definition of 'make'). - Spydertrader
Impressive. We have a new record here. So it is more than 200% now. Assuming you agree with bonecrusher and rewrite his answer (if he does not beat you in the meantime by responding faster), you will be the next king holding the crown. Make sure you will not be unseated. Let us assume interest=5%.
We could make a lot more as we continue to short more shares on the way down. Is this breaking the rules in your equation?
This isn't equities but I've been shorting gold since April 1st and I'm up 84% on my account and I expect gold to continue to decline so should be over 100% soon...
