COST — long thesis
Thesis
COST (Costco) — GATE EVALUATED AND SATISFIED (Aug 19, supervisor item 76): (a) staples have outperformed SPY multi-session (+1.4% vs -0.59% Aug 18; +1.6% vs +0.32% Aug 19; +2.2% 5d vs flat index) and (b) COST is holding/extending the post-announcement level (green today, trading near its highs, no adverse reversal; RBC calling it one of the best stories in retail; July net sales +10.7% with comps +8.9% confirm operating momentum). The original rationale stands: the Medicare-adjacent health-services initiative (product signal — the system's strongest category) extends the membership flywheel into recurring healthcare spend, inside the regime-favored defensive sector. Watch converts to formation-mode entry this session.
Triggers
Entry: Position held — the Aug 19 gate-satisfied fill has persisted in portfolio state (Aug 20 verify-first re-issue correctly skipped; delayed-persistence resolved). Conditional entry and gate language retired — managed as a held formation position under standing exit triggers. No adds while formation-mode sizing governs.
Exit: If entered: take profit at 8-12% from cost; stop loss at 7% below cost; trim if staples underperform SPY for 3+ consecutive weeks or membership/comp-sales momentum breaks at the next monthly sales release.
Invalidation: The health-services initiative is walked back or shows no membership attach. Staples leadership reverses as the rate regime turns dovish. Valuation de-rating: close below the pre-announcement base on volume. Comp sales decelerate materially.
