难道hedge fund的人都是傻瓜,就这个版上的各位大神最聪明。
数据是 90%以上的hedge fund的人不能做不到。数据是 hedge fund有非常多的钱,想找多聪明的人给他们打工 都能找的到。藤校毕业的,各大名校的教授,nobel奖获得者,想挖那个都挖的到。但是还是只有很少的人能beat sp500.
how many hedge fund beat sp500 in the last 20 years
ChatGPT said:
It’s hard to get a precise number of hedge funds that beat the S&P 500 over the past 20 years, because of variability in definitions, survivorship bias, different hedge fund strategies, and the fact that many reports don’t break out 20-year performance neatly. But the data we do have suggests the proportion is quite small. Here’s what I found:
What the available data says
Average hedge fund returns vs. S&P
Many sources say that the average hedge fund underperforms the S&P 500 over long periods once fees are accounted for.
Fraction of hedge funds that do outperform
One study found only 6.6% of 3,000 hedge funds outperformed the market during the 10-year period from 2014-2024.
SmartAsset
Another source indicates that over a 5-year period, maybe 30% could consistently beat benchmarks, but that number drops sharply over longer horizons.
Trends over 20 years
It seems likely that fewer than 10-15% of hedge funds have truly beaten the S&P 500 over a full 20-year stretch, particularly after fees and adjusting for risk. Some articles suggest that over very long horizons, maybe only “a small fraction” manage to do so.
My best estimate
Based on what I found, my estimate would be that fewer than 10% of hedge funds have outperformed the S&P 500 net of fees over the past 20 years.
