    Thesis

    Broader chip export restrictions lower expected semiconductor revenue, and the sector falls over the next month.

    SMH (VanEck Semiconductor ETF) is the sector proxy.

    Evidence

    Observed

    • Daily closes from stored price history.
    • Beta and R² against SMH.

    Assumed

    • Long-only stock and ETF positions (no short selling is modeled).
    • Option values are Black-Scholes estimates; no quoted contract.

    No candidate meets these criteria. Each row above states why.

    Sizing basis: $10,000 per candidate — equal dollars are not equal exposure; the exposure column shows capital × beta for stocks/ETFs and premium outlay for spreads. Scenario = beta × SMH move of -10% over 30 days; adverse = the opposite move (spreads: full premium). Candidates need fit ≥ 15%. Quotes: last stored daily close (SMH 2026-10-14) — historical; current calculations need fresh prices. Engine trade-expression-v1.

    Countercase

    • Restrictions are often priced in before formal publication.
    • Companies can redirect supply to unrestricted customers, limiting revenue loss.

    Conditions

    Enter / review

    • A listed SMH put contract near the modeled strikes is available.

    Wait

    • The restriction text and effective date are not yet published.

    Reject

    • Any long position under a decline scenario.
