AI and semiconductor stocks, including TSMC and Micron, declined amid concerns over unsustainable valuations and AI profitability, while broader tech indexes fell due to global market weakness.
verdict REPRICING, direction bearish -> sell TSM (other: AI and semiconductor stocks, including TSMC and Micron, declined amid concerns over unsustainable valuations and AI profitability, while broader tech indexes fell due to global market weakness.)
overnight drift: sell TSM at close, exit next close (other: AI and semiconductor stocks, including TSMC and Micron, declined amid concerns over unsustainable valuations and AI profitability, while broader tech indexes fell due to global market weakness.) [skipped at close: duplicate — already holding S4 sell TSM exiting 2026-07-20]
Entry vs. outcome: The bearish call was based on broad sector sentiment ("AI valuation concerns") rather than anything TSM-specific, and the trade essentially validated that vagueness — it captured only +0.78% of a move that reached +1.81% unrealized, meaning you gave back more than half the edge before exit. The "REPRICING" verdict fired on generic macro headlines, which produces low-conviction trades with tight profit windows.
Improvement: Require the REPRICING verdict to cite a ticker-specific catalyst (earnings, guidance, order data) rather than sector-wide sentiment; alternatively, if you keep sentiment-driven entries, pair them with a mechanical trailing stop or partial take-profit around +1.5% since these headline-driven moves demonstrably mean-revert fast.
📖 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.
