Novavax shares fell 8.7% this afternoon. The drop came after the PPI inflation report showed producer prices rose 0.5% last month, which was higher than the 0.3% economists expected. This sparked concerns that the Fed might keep interest rates higher for longer. The stock has been moving a lot lately. Just yesterday it jumped 24% after reporting Q4 revenue of $147.1 million and a surprise profit of $0.11 per share. Despite today's drop, NVAX is still up about 42% since the start of the year.
