Health care stocks, with subdivisions including biotechnology, pharmaceuticals, insurance providers and telemedicines, have come into focus as the world grapples with a health crisis that is not going to end any time soon. With the need for medical supplies as well as care and medicine, many health care stocks have begun to make names for themselves amid the pandemic. Biotechs like Moderna Inc. (MRNA  ) and Inovio Pharmaceuticals Inc. (INO  ) have become frontrunners for a COVID-19 vaccine and Johnson & Johnson (JNJ  ) stated that their candidate could be available in 2021. Gilead Sciences (GILD  ) antiviral drug Remdesivir is beginning to show signs of positive treatment results in coronavirus patients. Other big names that may be benefitting from the pandemic include the United State's largest health insurance provider UntiedHealth Group (UNH  ) as well as newly popular telemedicine company Teladoc (TDOC  ), both of which reported stellar first quarter results despite the stock market slump. It seems that now more than ever a great time to invest in health care.

This fund providers exposure to health care equipment and supplies, insurance providers and services, as well as biotechnology holding a significant portion of holdings. Heavy weight pharmaceuticals account for nearly 33% of the funds components and the fund is relatively cheap compared to other healthcare ETFs. All and all, XLV is a relatively safe and cheap trade.

Vanguard Health Care ETF (VHT  )

VHT offers the broadest exposures to all aspects of the health care sector with 389 stocks within this fund. The ETF is also cheap to hold, with low fees and excellent tracking.

iShares U.S. Healthcare ETF (IYH  )

IYH also gives an investor great exposure to health care sector, holding the industry's largest pharmaceuticals, medical and biotechnology companies that trade on Wall Street. Popular and reliable, this fund trades well, but not to the same degree at XLV and contains higher holding costs.

Invesco S&P 500 Equal Weight Health Care ETF (RYH  )

This ETF holds health care stocks along the S&P 500 (SPY  ) with equal weights. RYH has less concentration in pharmaceuticals due to its more balanced exposure to the sector. RYH trades well, but comes at a higher cost.

Invesco DWA Healthcare Momentum ETF (PTH  )

PTH is an alternative take on the health care sector, with emphasis on biotechnology and research over pharmaceuticals and health care providers. This narrow fund only has 47 holdings, with small tilts and more risk compared to other health care ETFs.
