We were also able to identify in advance a select group of hedge fund holdings that underperformed the market by 10 percentage points annually between 2006 and 2017. Interestingly the margin of underperformance of these stocks has been increasing in recent years.

Keeping this in mind let’s analyze the fresh hedge fund action encompassing Spero Therapeutics, Inc. (NASDAQ:SPRO).

How are hedge funds trading Spero Therapeutics, Inc. (NASDAQ:SPRO)?

Heading into the second quarter of 2020, a total of 7 of the hedge funds tracked by Insider Monkey held long positions in this stock, a change of 0% from one quarter earlier. Below, you can check out the change in hedge fund sentiment towards SPRO over the last 18 quarters. So, let’s see which hedge funds were among the top holders of the stock and which hedge funds were making big moves.

Among these funds, Aquilo Capital Management held the most valuable stake in Spero Therapeutics, Inc. (NASDAQ:SPRO), which was worth $14.7 million at the end of the third quarter. On the second spot was Rock Springs Capital Management which amassed $4.9 million worth of shares. Biotechnology Value Fund / BVF Inc, Renaissance Technologies, and DAFNA Capital Management were also very fond of the stock, becoming one of the largest hedge fund holders of the company. In terms of the portfolio weights assigned to each position Aquilo Capital Management allocated the biggest weight to Spero Therapeutics, Inc. (NASDAQ:SPRO), around 5.73% of its 13F portfolio. Biotechnology Value Fund / BVF Inc is also relatively very bullish on the stock, earmarking 0.42 percent of its 13F equity portfolio to SPRO.

We view hedge fund activity in the stock unfavorable, but in this case there was only a single hedge fund selling its entire position: OrbiMed Advisors. One hedge fund selling its entire position doesn’t always imply a bearish intent. Theoretically a hedge fund may decide to sell a promising position in order to invest the proceeds in a more promising idea. However, we don’t think this is the case in this case because only one of the 800+ hedge funds tracked by Insider Monkey identified as a viable investment and initiated a position in the stock (that fund was DAFNA Capital Management).

Let’s also examine hedge fund activity in other stocks similar to Spero Therapeutics, Inc. (NASDAQ:SPRO). We will take a look at U.S. Xpress Enterprises, Inc. (NYSE:USX), Gaia, Inc. (NASDAQ:GAIA), Nymox Pharmaceutical Corporation (NASDAQ:NYMX), and Misonix, Inc. (NASDAQ:MSON). This group of stocks’ market values are closest to SPRO’s market value.
