Is TNDM Stock A Buy or Sell?

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 Melvin Capital’s recent GameStop 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 Tandem Diabetes Care Inc (NASDAQ:TNDM).

Is TNDM stock a buy? Money managers were taking a pessimistic view. The number of long hedge fund positions fell by 4 lately. Tandem Diabetes Care Inc (NASDAQ:TNDM) was in 26 hedge funds’ portfolios at the end of December. The all time high for this statistic is 39. Our calculations also showed that TNDM isn’t among the 30 most popular stocks among hedge funds (click for Q4 rankings).

So, why do we pay attention to hedge fund sentiment before making any investment decisions? Our research has shown that hedge funds’ small-cap stock picks managed to beat the market by double digits annually between 1999 and 2016, but the margin of outperformance has been declining in recent years. Nevertheless, we were still able to identify in advance a select group of hedge fund holdings that outperformed the S&P 500 ETFs by more than 124 percentage points since March 2017 (see the details here).
