Q
Highlights:
CTAs have a 50% survival rate; better than daytraders or new business failure rates, but significantly less than mutual funds
Survivors are better performers, but the best performers weren't necessarily the survivors
Monthly returns weren't indicative of survival capabilities; as in the "trader's edge" did not give the CTAs an edge in surviving
Survivors survive by praticing money management:
1) they experienced lower than average max drawdowns
2) recovered from drawdowns faster and more consistently
3) were less volatile
4) had better Sharpe ratios than non-survivors
There was no advantage of a "diversified" or "non-diversified" CTA, but systematic CTAs were better survivors than discretionary CTAs
Variables that influenced mortaltiy rates: max monthly return, sharpe ratio, avg monthly winning return, management fee, incentive fee, std dev of monthly returns, max monthly drawdowns, max time to recover from drawdown as % of business life, and max # of months to recover from drawdown.
