Here's Why BioNTech Lost 18.7% in April
Shares of BioNTech (NASDAQ: BNTX) tumbled nearly 19% last month, according to data from S&P Global Market Intelligence. That doesn't compare favorably with the 12.7% gain of the S&P 500 during that time, but it was simply a matter of timing.
Shares of the German biotech soared in March after the company announced it had partnered with Pfizer (NYSE: PFE) to develop a vaccine against the SARS-CoV-2 virus that causes COVID-19. In other words, the decline in April was really just a correction. Through May 1, the pharma stock has gained 33% since the beginning of the year, while the S&P 500 has declined 12.4%.
