On CAPS, 96% of the 140 members who have rated Vanguard Health Care believe the ETF will outperform the S&P 500 going forward. These bulls include GreatorGator and dumberthanafool.

Last year, GreatorGator tapped the ETF as a healthy way to diversify:

Health Care is a beaten down industry that should fare far better in the future. Tough to pinpoint which company will profit from the next big thing. ETF allows us to own a piece of everything.

Vanguard Health Care, in particular, sports an expense ratio of 0.24%. That's lower than other health care ETF plays like iShares Dow Jones US Healthcare (0.47%) and iShares SP Global Healthcare (0.48%).

CAPS member dumberthanafool elaborates on the bull case:

[B]y investing in VHT I can greatly diversify my health care exposure, while still maintaining my bet on the investment future of the health care industry in this country, which is based on its current relative low valuation, and the not-original idea that baby boomers are going to consume a lot of health care. VHT is probably the best way to bet on that, unless one is a genius stock-picker, which I have increasingly begun to suspect I am not.
