ARVN PDUFA June 5. Every calendar treats it as normal oncology. It isn't. ARVN scanner reads 81.9% PoA. But there's no historical base rate for FDA reviewing a PROTAC. submarinecatalyst.com $ARVN

$RCKT approved and dropped 20%. Approval ≠ stock move. Added a Sell-The-News Risk Score to the scanner. Every event now gets two ratings, will it get approved, and is the approval worth trading. RCKT would have flagged HIGH. submarinecatalyst.com/track-…

$RCKT approved today. Scanner had it at 77.5% PoA. That's 5 for 5 on resolved PDUFA events. VNDA ✓ FBIO ✓ VNDA ✓ DNLI ✓ (early) RCKT ✓ $TVTX next — April 13. submarinecatalyst.com/track-…

$DNLI approved yesterday early, before the PDUFA date. Scanner had it at 77.5% PoA / STRONG. Didn't have a position the scanner scores every event, not just my trades. 4 for 4 on resolved PDUFA events. 100% accuracy. $RCKT is next — March 28, 3 days out. submarinecatalyst.com/track-…
