Quote from Ghost of Cutten:
You could replicate this by just buying the S&P with a bit of leverage. E.g. 150% long S&P. You would outperform for years until one year you get a margin call blow up. Only 2008, 1973-74, 1937, 1929-32, 1907 would have triggered a margin call in the last 110 years on a 150% long account, in the USA anyway. So you have a good chance of doing well, attracting client capital, and creaming off the fees by writing hidden OTM puts.
In fact this would be a great business model for unethical traders. Simply leverage the S&P, throw in a few random offset positions long & short on small size to disguise your closet indexing, and write some political bullshit and trading saws in your quarterly newsletter. Outperform 4 years out of 5, funnel your bonus each year into safe haven assets. If you hit a killer bear market then just fold the fund, blame 'unforseen events', and laugh as your T-bonds go up 20%, cash in, then re-open a year or two later with an 'improved hedging strategy'. The market has just tanked 40%+ the 1-2 years before, so odds are it's another 5+ years before another repeat, that's good enough to have a big run and prove yourself as a 'comeback king'.
