RE:What’s going on
This is for sure a macroevent, nothing to do with WELL specifically. Large sell-off, hitting tech stock highfliers the hardest. Hard to trade off this unless you have immediate access to headlines or inside tweets. The below seems to be the reason for the sell-off which has been in place for several days, but is very sharp today:
"Stocks dropped as traders awaited clarity from Federal Reserve Chairman Jerome Powell on how the central bank is perceiving the recent spike in Treasury yields."
