MRVL — long thesis
Thesis
MRVL custom-AI silicon share-gain long — Marvell surged after Google struck an AI chip deal with it (Aug 19, product/bullish/high), a direct market-share win in custom AI accelerators against incumbent Broadcom. Product signals are the system's strongest live category (+5.51% avg alpha, 77% beat-market), and this is a hyperscaler design-win — the most durable kind of product catalyst in AI silicon (multi-year, multi-generation programs). The trade pairs coherently with this session's AVGO de-risk: same variable (Google custom-silicon allocation), opposite sign — this shifts exposure from the share-loser to the share-gainer rather than adding net semi beta. Post-catalyst confirmation entry akin to the FN pattern: the announcement has already resolved, this is not a chase into a binary. Formation size only (Rule #1); tech tape remains soft (-0.9% 1d), so sizing stays minimal.
Triggers
Entry: Position held — the Aug 19 fill has persisted in portfolio state (Aug 20 verify-first re-issue correctly skipped by the executor; delayed-persistence resolved). Conditional entry language retired. No adds at formation size while the elevated-yield regime persists and ahead of the NVDA Aug 26 sector binary.
Exit: Take profit at 12-15% from cost. Stop loss at 8% below cost. Trim if the Google program is reported delayed/descoped or on confirmed hyperscaler AI-capex cuts. Rule #5 partial applies ahead of the next quarterly print if up ≥5%.
Invalidation: Post-catalyst momentum fails: close below the pre-announcement base on volume. The Google deal is denied, descoped, or reported as smaller than framed. Broadcom announces a counter-win reclaiming the allocation. Confirmed hyperscaler AI-capex cuts (financing-driven demand break).
