BHVN - UBS hunts crowded trades: Most overweight underweight stocks

A new report from UBS looks to dig into the most crowded trades in the market - the 10 stocks that are most overweight among global active investment funds, as well as the 10 most underweight. It's gone about that by forming an active trading portfolio aggregating positions across global active managers: summing up all the holdings in dollar value, and then calculating the weights of the stocks in that mega-portfolio. Determining the active weight that UBS is using as s sort mechanism comes from comparing those weights with the relevant equity index benchmark. The firm also excludes holders that they determine to be insiders. And on that measure, looking globally, the most overweight stock by far is General Electric (NYSE:GE). It had an "active weight" measure of 1.02% in the UBS metric, far ahead of the next few stocks on the "overweight" list: Visa (NYSE:V), at 0.29%, Facebook (NASDAQ:FB),
