Semiconductor stocks have entered a bear market with elevated volatility concentrated in the chip sector, erasing $3.3 trillion in value despite broader market resilience.
verdict FRESH, direction bearish -> sell NVDA (other: Semiconductor stocks have entered a bear market with elevated volatility concentrated in the chip sector, erasing $3.3 trillion in value despite broader market resilience.) [skipped: signal conflict — wanted sell but open S1 buy NVDA exiting 2026-07-22] → close +2.65%
verdict FRESH, direction bearish -> sell AMD (other: Semiconductor stocks have entered a bear market with elevated volatility concentrated in the chip sector, erasing $3.3 trillion in value despite broader market resilience.)
overnight drift: sell NVDA at close, exit next close (other: Semiconductor stocks have entered a bear market with elevated volatility concentrated in the chip sector, erasing $3.3 trillion in value despite broader market resilience.) [skipped at close: signal conflict — wanted sell but open S4 buy NVDA exiting 2026-07-23]
Entry vs. outcome: The "FRESH" verdict was wrong on its face — a headline about $3.3T already erased describes a move that has happened, not one about to happen, so you shorted AMD after the sector-wide damage was priced in. The trade never got more than +0.38% in your favor while sitting through a -2.29% adverse swing, meaning the edge was gone at entry and you were just holding risk.
Improvement: Add a staleness filter to the FRESH verdict: disqualify (or downgrade to STALE) any rationale citing cumulative/completed price action ("erased," "has entered," "has fallen") unless paired with a forward-looking, ticker-specific catalyst. Alternatively, require sector-macro theses to pass a momentum confirmation on the specific ticker before entry — broad-brush chip-sector narratives shouldn't auto-trigger single-name shorts.
📖 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.
