New watches

LULU $104.06

Structural watch

Americas comps −12% while On grows; test company-specific brand/product issues, not proven share loss.

Rebuttal: Cash, profits and lower unit inventory rebut the short; about 12x normalized EPS prices in much weakness.

Conditional review zone: $125–140
Conditional cover: $85–95 / $70–80

A rebound plus Americas comps ≤−10%, weaker core profit/cash and stronger peers.

Q3 date unverified; new CEO took office in September.

LOGOS →Primary source

BBAI $2.13

Structural watch

Acquisition mix, cash burn and ATM dilution warrant review; M2 share loss is unproven.

Rebuttal: Awards, renewals, positive pro-forma growth and $410M cash/investments are rebuttals.

Conditional review zone: $3–3.5
Conditional cover: $1.4–1.8

Oct27: organic bridge, funded awards, collections and ATM shares; reassess after a rebound plus operating failure.

Oct27 after close; 16:30 EDT call.

Existing priorities: both await lower costs

Jan 15, 2027 put spreads: buy the higher strike, sell the lower. Higher option prices do not raise research limits.

Ticker / strikes	Max debit / share	Natural / mid debit	Initial risk cap
AI 12.5/7.5	$1.65	$1.70 / $1.565	≤0.15% NAV
HIMS 30/20	$3.50	$4.46 / $4.040	≤0.1% NAV

AI natural debit 1.70 exceeds 1.65; HIMS 4.46 exceeds 3.50. Both fail the cost gate. Midpoints are not fills. At the limits, maximum contractual losses are $165/$350 per spread, plus fees within risk budgets.

Underlying regular closes are Oct 22. Response timestamps omit timezone and are preserved as received. US session closed; refresh broker combination quotes, fees, deliverables and news next session. No fills.

Rebuttals: no short now

TXNOct21 revenue +28%; ordinary TTM FCF $7.318B covers returns, rebutting a cycle short. Source
SMCIOct20 raised revenue and margin estimates, rebutting extrapolated weakness. Source
WDCTonight revenue +55%, FCF $1.377B and stronger EPS outlook; a post-market fall is not cycle failure. Source
FIXTonight revenue +54%, EPS $13.91, CFO $1.01B and strong same-store backlog. Source
BYNDQ2 revenue −8.2% and cash burn, but no verified new company catalyst after Oct16. Source

PENG received a price-only update. CRDO, FRMI, SMR, APLD and other prior watches have not been fully revalidated; no new entry proposals.

Risk and exits

Structural shorts require M2 share loss linked to M4/M5; cyclical shorts test M1 demand and M3 margins. Events are catalysts, not a third mechanism. HIMS/PENG remain unclassified. An unsuitable long or falling price does not establish a good short.

Premium risk including fees: ≤0.25% NAV per thesis, ≤1% total. Review/exit on a 50% spread loss or business invalidation; gaps can lose all premium. No naked short without borrow quotes; these are not precise AI-long hedges.

If AI/HIMS spreads are later filled, close the whole spread by Jan 8, 2027; no automatic roll. Actual premiums use cash. Current committee targets: 88% stocks / 12% cash; research adds no executed short allocation.
