Founder @ Submarine Catalyst | PDUFA Binary Event Intelligence for Biotech Traders

[Davis Rackler @DRackler]

I built a PDUFA scoring engine.

60 live FDA events. 7 evidence layers. AI research tool.

Navy sub vet → biotech trader → built the tool I needed.

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.

Wins logged on the same record: $VNDA +45%, $TVTX +33%, $SNY +2%, $LGND +14%, $DNLI +8%, $BIIB -5% (called short)

[Davis Rackler @DRackler]

I built a quantitative PDUFA scoring system for 300+ biotechs. Solo.
9 of 11 on resolved live calls.
Both misses were CRLs ($GRCE, $REPL).
Portfolio sim posted on the landing page at -0.8%, drawdowns and all.

New to biotech trading? Just published a free beginner's guide.

Covers everything: PDUFA dates, CRLs, AdCom votes, NDA vs BLA, short squeezes, sell-the-news traps, and how to read a scanner card.

No paywall on education. Learn first, trade smarter.

$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.

[Davis Rackler @DRackler]

$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.

[Davis Rackler @DRackler]

$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.
https://t.co/YCvWg3K5BC

[Davis Rackler @DRackler]

The scanner just flagged $RCKT as STRONG — 77.5% PoA, PDUFA March 28.

Every score is auditable. No black boxes.

Free calendar with 60 events. Paid subscribers get full scores + AI deep dives.
