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. (long, medium confidence)
