As an investor, it’s one thing to have conviction in your decisions. But it’s quite another to press your luck to the point where any sort of downturn can have a catastrophic impact on your portfolio.
The firm analyzed the holdings of 880 hedge funds with $2.1 trillion of gross equity positions and found that a measure known as “density” is historically stretched. More specifically, Goldman found that the average hedge fund holds 70% of its long portfolio in its top 10 positions — the highest portion since at least 2002.
But why exactly does this metric matter? Because when positions get crowded like this, it leaves investors vulnerable to sharp sell-offs.
That’s because, at the first sign of stress, investors jammed into the same holdings will simultaneously stampede towards the exits. And that, in turn, can make a bad situation worse when it comes to a major market meltdown — especially for those who get out last.
So it almost goes without saying that — in the ominous event of a full-fledged stock-market crash— the last place an investor wants to be is piled into a crowded position. To the extent that hedge funds are still loaded up on the same popular names, the next downturn could be made worse.
With all of that established, it’s worth noting that doubling down on proven winners can be a lucrative strategy when everything is going swimmingly in the market. After all, hedge funds wouldn’t be cramming into those stocks with abandon if they weren’t offering strong returns.
Still, it would seem to be a prudent strategy for investors insistent upon staying invested in crowded stocks to seek some downside hedges. At the very least, they could help offset the damage once the tables turn on those high-density trades.
