One of the market’s hottest sectors over the past few weeks has been healthcare. The broader healthcare sector is now beating the S&P 500 by more than 2% year-to-date with certain subsectors doing even better. Short-term technical strength also suggests that this group could continue riding the momentum even higher.Q2 earnings have also been a driver of recent performance, especially in mid-caps and small-caps. The sector is having one of the more impressive quarters as far as earnings and revenue beats are concerned and many companies are experiencing the double tailwind of repatriated cash and lower corporate tax rates.Here are three healthcare ETFs to play the sector’s current strength.Healthcare Select Sector SPDR ETF (XLV)The largest ETF in the space, XLV is nearing a 9% YTD gain. If you’re looking simply for an ultra-low cost diversified portfolio, this is your best bet. Top holdings include Johnson & Johnson (JNJ), United Healthcare (UNH), Pfizer (PFE) and Merck (MRK).iShares U.S. Medical Devices ETF (IHI)Medical devices and healthcare equipment have been two of the best performing groups within healthcare. IHI is up 21% this year on top of a 31% gain in 2017. Top holdings include Medtronic (MDT), Abbott Labs (ABT) and Thermo Fisher Scientific (TMO).SPDR S&P Pharmaceuticals ETF (XPH)The pharmaceuticals group has gotten a lot of press lately thanks to President Trump’s battle with Pfizer over drug prices. XPH is an equally weighted portfolio of 21 names that has benefited from the rally in smaller companies. Its 8% gain isn’t quite as attractive as its peers but strong Q2 results and optimism that any potential cuts in drug prices might not be as negatively impactful as originally thought have helped fuel some of the gains. Top holdings include Mallinckrodt (MNK), Eli Lilly (LLY) and Bristol Myers Squibb (BMY).
