Isn’t 18 months post data lock enough to produce a publication? In the event they are unable to release publication by May, then stay patient until July? Very soon the narrative will shift to ASCO presentations (and placeholders!).
I don't get involved in others' investment decisions, especially regarding intelligent people such as flipper. However, it is a temperament business here in the stock market if you can't stand and wait feel free to sell. It's free-market after all. No one forcing anyone and no one should do.
