Hold on, it's not comparable to the ~10$ CAGR of the SP500 is it? RenTec's fund is capped so it's an average return of 71.9% but not an annualized return, since the returns are not compounded. Correct?
That's right, they dividend out the profits each year (or at least they started doing that once the fund got over ~$5b or so). Otherwise if you do the math (1.66^33) they would end up with most of the money in the world!
