Moderna is worth roughly $190-215 a share on a probability-weighted outcome tree, above the $157 price after its melanoma vaccine readout. Failure implies $75-85, melanoma-only $125-160, positive Phase 3 lung data $250-400, and broad cancer vaccination far more. The market is more skeptical on lung, and that readout decides the trade. With about 50M shares short, a squeeze could hit $400 before a return to a $120-190 range. Most outcomes sit at or below the price, so defined risk is warranted. x.com x.com x.com x.com x.com x.com x.com x.com
