Biotech stocks are shining in June after underperforming the broader indexes for the past few months. Last week was the best week for major biotech ETFs since November as Biogen’s (BIIB) stock surged after the FDA approved its Alzheimer’s drug.This was the first approval of an Alzheimer’s treatment in about two decades. Though there is some controversy about the approval and three members of an outside experts’ committee have since resigned over the decision, many analysts believe that the approval suggests a more supportive and constructive regulatory environment for drug approvals now.Some biotech stocks like Clover Health Investments (CLOV) and Inovio Pharmaceuticals (INO) surged as became popular with meme stock traders on forums like Reddit’s WallStreetBets.Last year, biotech stocks & ETFs had a strong rally, particularly as many companies were working on Covid testing, treatments and vaccines. This year, investors have rotated away from last year’s winners into cyclical areas, but biotech stocks and ETFs deserve a place in investors’ portfolios due to their excellent growth potential.Instead of trying to pick winners in this volatile space, it is better to invest in broader biotech ETFs that stand to benefit from increased investor interest and rising spending on drugs and healthcare all over the world.To learn more about the iShares NASDAQ Biotechnology ETF (IBB), Invesco Nasdaq Biotechnology ETF (IBBQ) and SPDR S&P Biotech ETF (XBI), please watch the short video above.
