Why do we pay any attention at all to hedge fund sentiment? Our research has shown that hedge funds' large-cap stock picks indeed failed to beat the market between 1999 and 2016. However, we were able to identify in advance a select group of hedge fund holdings that outperformed the Russell 2000 ETFs by 40 percentage points since May 2014 (see the details here). We were also able to identify in advance a select group of hedge fund holdings that'll significantly underperform the market. We have been tracking and sharing the list of these stocks since February 2017 and they lost 27.8% through November 21, 2019. That's why we believe hedge fund sentiment is an extremely useful indicator that investors should pay attention to.
