Rig: Without a net worth exceeding $1m AND an annual income exceeding $200,000, my understanding is the short and long answers both are: none of our business. Go to morningstar.com and click on "Hedge Funds." Seriously. Go do it.

They're like private equity firms, but not. That's the best explanation I've seen. I read somewhere that some of them play sophisticated day trend computer transactions, in such a manner that they pay high rent to install next to exchanges, to save microseconds of transmission time. Seriously.

Hope this helps.
