Moderna shorts just got absolutely wrecked — stock ripped 177% after melanoma trial hit. $8.7B in unrealized losses for bears.

Trial = win. Analysts already upgrading. Classic biotech short squeeze setup when fundamentals flip overnight.

If you were betting against $MRNA into a binary catalyst… ouch. This is why pharma plays are brutal — one data readout can vaporize your position.

Watch for follow-through or profit-taking next session. Shorts might still be covering.
