I have been noticing that myself for the last few months. I think it boils down to the only fact that anyone is willing to admit is that people who were already beating covid and going to get out of the hospital anyway got out 3 to 4 days earlier than placebo. I don't think the market is very impressed with that, I know i am definitely not. Its almost like its a "gap fill" drug till the real one comes along and I think the market sees that.
Of course the real one will be coming along soon!
