Shorting stocks is a risky investment strategy

  • Jeroen Blokland
    Portfolio Manager

As equities tend to trend higher most of the time, selling stocks to profit from falling prices requires above all impeccable timing. And it’s become a severe loss-making strategy. As today’s chart from Deutsche Bank shows, stocks with the highest short interest (the number of stocks investors have sold short but are not covered or repurchased) have massively outperformed the overall market. There are two things I would like to add here. First, being a perma-bear or extremely bearish is always a risky investment strategy. While overly downbeat stories make good headlines they often do not make healthy returns. Quite the contrary and today’s chart is just another example of this. Second, when you dig deeper you’ll see that some irrational exuberance is becoming visible in markets, but that these are mostly concentrated within the technology sector. Other sectors and regions show fewer signs of buoyancy. However, the popping of the Internet bubble in 2000 is a vivid reminder that one sector is perfectly capable of causing a market downturn.
