I'd go with XPH, because drug industry buyouts are booming, and XPH is built to benefit. Drugmakers like AbbVie, Merck, and Eli Lilly are racing to buy smaller drug developers as patents on their own best-sellers run out, and buyers have paid far above market prices to land the companies they want.
XPH gives smaller developers the same weight as bigger ones, so takeover targets get a real seat at the table. When Merck agreed to buy Terns Pharmaceuticals, a company XPH owned, that stock jumped more than 25% in March. Roughly 60 holdings mean no single deal or trial failure sinks the fund, and it costs less than IBB and pays a higher yield.
IBB is far larger and owns more than 200 companies, led by profitable names like Gilead, Amgen, and Vertex. But XPH puts more of your money in the smaller companies that buyers go after, and its worst drop over the past five years was no deeper than IBB's. For most long-term investors, XPH is the better way to play the deal wave.
