Just a warning. That's the 6th edition. It's now in 10th. I have the 9th edition (Global edition). If one wants to go through everything in the book, some math knowledge is required like like logarithms, Neper number, integrals, differentials, etc. I think anyone can skip the theoretical part of it and still get a good chunk of the book.
here is a free pdf of the 8th edition: https://math.dartmouth.edu/~m86f17/Downloads/Hull8thedition.pdf
RenTech's reality is Medallion Fund is only available to current and retired employees. Not unusual though. RenTech's three other funds (REIF, RIDAF and RIDGEF) are all open to the public and beat the S&P once again last year and year to date currently.
SPY 10 yr rtn ~ 14.5%, one yr ~26% with one negative year (2018). REIF better have no negative rtn so that on a risk adjusted basis it is better.
