Biotech stocks reversed course and closed the week ended June 25 higher, thanks to the positive broader market sentiment.

Coronavirus vaccine stocks  Pfizer, Inc. (NYSE:PFE) and Moderna, Inc. (NASDAQ:MRNA) experienced some weakness mid-week after a CDC panel found correlation between the companies' mRNA vaccines and cases of heart inflammation in young adults.

Atossa Therapeutics, Inc. (NASDAQ:ATOS) was among the biggest gainers of the week as recent news flow continued to impart momentum to the stock. The stock is set to join the Russell 2000 and 3000 Indexes next week.
