The PowerShares DWA Healthcare Momentum Portfolio (NYSEArca: PTH) is another of the small number of ETFs that feature Salix among their top-10 holdings. PTH is one of 10 PowerShares ETFs that in February transitioned to Dorsey Wright indices, which focus on identifying stocks with impressive relative strength.

PTH’s momentum focus has proven effective as the ETF has surged 8.6% over the past three months. The $78 million fund has an almost 3.6% weight to Salix. [Index Swap Already Helping This ETF]

That is about the same weigh the PowerShares Dynamic Pharmaceuticals Portfolio (NYSEArca: PJP) allocates to the stock. Of course a takeover of Salix by Allergan, or any other firm, would boost PJP, but the ETF has not needed much help delivering for investors this year. PJP is up nearly 17% and has added $96.5 million in new assets.
