Hedge funds should be compared to similar funds/indices that offer the same strategy. Event driven funds should be compared to other event driven funds, credit funds should be compared to other credit funds or a specific credit index that mirrors the strategy, long/short funds vs. other long/short funds, etc.... Comparing a fund's performance to a 60/40 portfolio doesn't make sense b/c that is assuming the investor would be willing to put their entire asset base into that specific hedge fund. Now if you put your money into an absolute return fund where the manager claims he can beat the market, then it would be appropriate to benchmark his performance against an equity index, but absolute return strategies are only a small part of the hedge fund industry.
