Claude picks vs random picks
Claude book (test): the same candidates, slot size, 25-position cap, exits and costs as the main book; only the selection differs. Every weekend each of the week's candidates gets a dossier (8-K guidance and press releases, current ClinicalTrials.gov records, recent papers, cash runway, offerings, other catalysts) and one Claude analysis (strongest available model, web search only) that estimates the chance the stock beats the equal-weight biotech basket by the planned sell date (p_runup), the chance of a binary event before it (p_early_shock) and a 0-100 score; the top 5 scores are bought. Scores are frozen before the Monday open. The main book's tie-order picks are effectively random within the same candidate set (the study found M's ranking no better than random), so this is Claude picks vs 5 random picks.
| Book | Account | Return | vs BIO-EW | vs XBI | Closed trades | Hit rate | Positions |
|---|---|---|---|---|---|---|---|
| Main book: 5 tie-order (random) picks | $1,000,000 | +0.0% | +0.0% | +0.0% | 0 | - | 0 |
| Claude book: Claude's top 5 | $1,000,000 | +0.0% | +0.0% | +0.0% | 0 | - | 0 |
Hit rate = share of closed trades with a positive return after costs. vs BIO-EW / XBI = return difference in points since the start (2026-10-19 open).
Claude's top 5 for the signals of 2026-10-16 (35 of 35 candidates scored; frozen 2026-10-16 22:55 New York time). Main-book picks this week: PEPG, ZURA, OLMA, ORKA, MGNX.
| # | Ticker | Score | p_runup | p_early_shock | Planned sell | Key reasons (Claude) |
|---|---|---|---|---|---|---|
| 1 | LBRX | 56 | 55% | 12% | 2026-12-29 | • FACT: NOVA-2 topline guided to 1H27 (reiterated 2026-09-15 and in the 2026-10-06 R&D Day release); CT.gov PCD is 2027-06 and the trial started 2026-03-25, so a readout before the 2026-12-29 sell date is unlikely. Early-shock risk … • FACT: Cash $327.8M at 2026-06-30 plus $150M PIPE at $34.94 closed ~2026-07-30 (runway guided beyond Q2 2029). JUDGEMENT: a dilutive raise inside the window is unlikely, though management has shown it will raise opportunistically. • FACT: Stock pulled back ~26% from $49.48 (2026-09-02) to $36.74 (2026-10-16), below its 50-day MA (~$43), after a Roth downgrade to Neutral/$35 (2026-10-05) and a Zacks 'strong sell' (2026-10-14); offset by Guggenheim ($80, 'best … |
| 2 | OLMA ★ | 55 | 55% | 15% | 2026-12-29 | • Pivotal OPERA-01 top-line guided to Q1 2027 (slipped from 'this fall' in May 2026); the planned sell date sits 3 trading days before the window, giving a classic pre-readout run-up window as the catalyst approaches. CT.gov … • Stock is at a 52-week low ($6.58, -82% from high, -33% in 20d) after the August data delay and the 2026-09-14 AstraZeneca SERENA-4 (camizestrant+palbociclib, 1L) failure; market cap $576M vs $461M cash (EV ~$115M) leaves a deeply … • SERENA-4 read-through is to the 1L combination setting (OPERA-02), not OPERA-01's post-CDK4/6i monotherapy-vs-SOC setting, where oral SERDs have a consistent class record (EMERALD/EMBER-3/VERITAC-2 all positive vs fulvestrant); … |
| 3 | TECX | 55 | 54% | 12% | 2026-12-29 | • Guided TX45 APEX Phase 2 topline 'early Q1 2027' (narrowed from 'late Q4 2026 or early Q1 2027' in May); last patient enrolled June 2026 + 24-week treatment puts last visits ~Dec 2026, so data before the 2026-12-29 sell date is … • Stock has sold off hard into the catalyst (-24% 20d, -35% 60d, -46% from 52-week high, $20.65 close) with UBS initiating at Neutral/$26 PT on 2026-10-11; no company-specific negative news found to explain the slide, which leaves … • Balance sheet strong: $227.1M cash at 2026-06-30 (~56% of $404M market cap), runway guided into Q1 2029; makes a dilutive offering before data unlikely, though the company did use its ATM ($11.7M net in Q2 2026). |
| 4 | DYN | 54 | 55% | 12% | 2026-12-29 | • Stock sits at its 52-week low ($14.25, -47% from high, -40% over 60d) after the 2026-09-08 Novartis/Avidity HARBOR Phase 3 miss on vHOT in DM1 drove a ~30% read-through selloff; this creates an oversold setup into two … • Dual catalyst stack just after the sell date: z-rostudirsen PDUFA 2027-01-21 (Priority Review) and ACHIEVE REC topline in Q1 2027; the holding period ends 2026-12-29, inside the typical pre-PDUFA run-up window. • Key risk to the bull case: ACHIEVE REC primary endpoint is 6-month vHOT, the same endpoint HARBOR failed on at 54 weeks; sentiment on DM1/vHOT remains impaired (Morgan Stanley PT cut to $36 in Sept; HCW cut to $32), so negative … |
| 5 | RNAC | 54 | 54% | 15% | 2026-12-29 | • Setup fits a classic pre-Phase-3 run-up: AURORA (128 pts enrolled, ACTIVE_NOT_RECRUITING, est. primary completion 2026-12-30) topline reaffirmed for 1Q27 in the 2026-09-29 8-K; the sell date (2026-12-29) sits just before the … • Stock is depressed: $6.27, -22% over 20d, -41% from 52-wk high, only +7% above 52-wk low, and fell from $7.28 (2026-09-30) despite positive retreatment data on 2026-09-29. No specific cause for the October slide was found … • Discrete-offering risk is moderate-low: $147.6M cash at 2026-06-30 vs ~$77M TTM burn, plus $50M K2 term loan drawn 2026-05-22 (company stated runway into 2028 per 2026-05-26 release seen in search). But the Leerink ATM is active … |
★ = also a main-book pick this week. Claude's reasons are model output with web search; they can be wrong.
Quintile test: no completed holding windows yet (0 weeks so far; the first planned sell dates are at the end of December 2026).
Calibration table (p_runup vs realised): appears once the first holding windows have ended.
Shadow book V1 (test)
Shadow book V1 (tracked, not the real book): the same rules, but any scheduled catalyst counts - 8-K readout timing guidance, a PDUFA date or an FDA advisory committee meeting 40-100 weekdays ahead - and only topline-result 8-Ks trigger an early sale. In the study V1 beat M in 2020-22 and 2023-26, but that was found after the fact, so M stays the real book.
Holds (0): none
Next open - buy: VNDA (pdufa 2026-12-12), ANAB (pdufa 2026-12-12), MLYS (pdufa 2026-12-22), PRAX (pdufa 2026-12-27), COGT (pdufa 2026-12-30); sell: none
