Hedge fund interest in Sientra Inc (NASDAQ:SIEN) shares was flat at the end of last quarter. This is usually a negative indicator.

(NASDAQ:PRPL) to get a better sense of its popularity.

Hedge funds’ reputation as shrewd investors has been tarnished in the last decade as their hedged returns couldn’t keep up with the unhedged returns of the market indices. 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 market by 40 percentage points since May 2014 through May 30, 2019 (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 30.9% through May 30, 2019. That’s why we believe hedge fund sentiment is an extremely useful indicator that investors should pay attention to.
