Ok stranger on the internet :). How about this. You pick 20 hedge funds. If over the next 20 years they return more to investors after fees and such than the Vanguard S&P 500 Admiral fund you win, otherwise I do?

I'd even let you change your list Jan. 1st of each year as long as we agree that any hedge fund found to be a fraud of some kind counts as a zero in your sum.

This is actually a pretty good bet for you given how poorly one would expect stocks to perform over the next 10 years
