Apple has surpassed Nvidia to become the world's most valuable company with a market capitalization of approximately $4.88 trillion compared to Nvidia's $4.85 trillion.
verdict REPRICING, direction bullish -> buy AAPL (other: Apple has surpassed Nvidia to become the world's most valuable company with a market capitalization of approximately $4.88 trillion compared to Nvidia's $4.85 trillion.)
overnight drift: buy AAPL at close, exit next close (other: Apple has surpassed Nvidia to become the world's most valuable company with a market capitalization of approximately $4.88 trillion compared to Nvidia's $4.85 trillion.) [skipped at close: duplicate — already holding S4 buy AAPL exiting 2026-07-20]
The entry rationale is weak: "Apple overtook Nvidia in market cap" is a backward-looking milestone that describes price action already in the books, not new information that should cause a repricing — and the outcome confirmed it, with the trade chopping in a ±1% band and scratching out +0.39%, indistinguishable from noise. The verdict REPRICING was mislabeled; nothing was being repriced, the market had already done the pricing. Concrete fix: exclude ranking/milestone headlines (market-cap crossovers, index inclusion rumors, "biggest ever" stats) from the REPRICING category entirely, and require the catalyst to contain forward-looking information (earnings, guidance, product, regulatory) with an expected move exceeding, say, 1.5x recent daily ATR before a trade is permitted.
📖 Glossary
S1 primary — trades the alert's primary ticker in the direction the article itself indicates; exits at the same day's close.
S2 counterparty — trades the inferred counterparty ticker (weakest signal, LLM-inferred sympathy); exits at the same day's close.
S3 peer — trades an inferred peer ticker (also LLM-inferred sympathy); exits at the same day's close.
S4 overnight — holds the primary ticker from today's close to the NEXT day's close.
Verdicts are decided top-to-bottom, first match wins; REPRICING is also the fallback when nothing else matches (2026-08-08 #220).
UNKNOWN — a needed price input (move since close or move in the last 30m) is missing.
PRICED — |move since previous close| ≥ 2.0%: already reflected in price.
REPRICING — |move in the last 30m| ≥ 0.5%: the tape is actively moving on it. Also covers a quieter move — |move since previous close| in [1.0, 2.0) with a quiet last-30m tape: still developing, not yet priced.
FRESH — |move since previous close| < 1.0%: a genuinely new move.
materiality — how market-moving the story was judged, 0-100 — alerts require materiality ≥ 60.
