Hedge Funds Are Selling Mellanox Technologies, Ltd. (MLNX)

We know that hedge funds generate strong, risk-adjusted returns over the long run, therefore imitating the picks that they are collectively bullish on can be a profitable strategy for retail investors. With billions of dollars in assets, smart money investors have to conduct complex analyses, spend many resources and use tools that are not always available for the general crowd. This doesn’t mean that they don’t have occasional colossal losses; they do (like Peltz’s recent General Electric losses). However, it is still a good idea to keep an eye on hedge fund activity. With this in mind, as the current round of 13F filings has just ended, let’s examine the smart money sentiment towards Mellanox Technologies, Ltd. (NASDAQ:MLNX).

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 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 25.7% through September 30, 2019. That’s why we believe hedge fund sentiment is an extremely useful indicator that investors should pay attention to.


Unlike some fund managers who are betting on Dow reaching 40000 in a year, our long-short investment strategy doesn’t rely on bull markets to deliver double digit returns. We only rely on hedge fund buy/sell signals. We’re going to take a look at the recent hedge fund action regarding Mellanox Technologies, Ltd. (NASDAQ:MLNX).
