The market is trying to recovery. The difference between NVAX, XBI & MRNA is notable as nibbling on Novavax shares started before the nibbling on XBI & MRNA. That is my impression based on the 5-minute charts and the uptick in price seen on NVAX and not XBI or MRNA.
The first chart below is NVAX, the second chart is XBI and third is MRNA.
