verdict REPRICING, direction bullish -> long GOOGL (other: Berkshire Hathaway made a $10 billion investment in Alphabet shares, marking its first net equity buying in over three years.)
overnight drift: long GOOGL at close, exit next close (other: Berkshire Hathaway made a $10 billion investment in Alphabet shares, marking its first net equity buying in over three years.) [skipped at close: outranked — mat 65 long lost to mat 65 long (decision 12740) for S4 GOOGL exiting 2026-08-25]
The bullish direction may have been correct on the news, but by entry the stock had already gained +1.18% from the prior close and was flat-to-down in the last 30 minutes — the repricing was largely done before the fill. Timing is the dominant factor: after entry the trade never had more than +0.08% available and bottomed at -0.29%, so the -0.68 point loss (exit at roughly -0.19%) is within the trivial range that existed; the exit didn't leave meaningful profit on the table. Whether the signal itself was wrong or merely stale can't be settled from this window alone — there was simply no post-entry move to capture.
📖 Glossary

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.
