Hedge funds own more than 20% of Rightmove, a British real estate platform. And yet it seems to have fallen out of favor. While its share price remains near its recent record high, it has attracted more than its share of short interest. That combination of percentage owned by the hedge fund universe and value of short positions make it the most "crowded" short in Europe.
It doesn't appear to be the funds themselves that are shorting it to any great degree, nor are they covering those shorts. Maybe they're just waiting to buy on the dip.
Other crowded shorts include publisher Pearson, oilfield services firm PGS, home furnisher home24 and shared-office host IWG.
