Retrospectives
| ticker | mfe | mae | reflection |
|---|---|---|---|
| GOOGL S1 | +0.80% | -1.09% | Signal: Wrong — the bearish call didn't play out; GOOGL rose ~0.76% against the short during the hold. Timing: The stock was already down 0.58% from prior close at entry, so part of any bearish reaction to the news may have been priced in, though the data here can't confirm the news itself caused that dip. Exit: Poor — the trade saw +0.80% unrealized in its favor at best, but exited at -0.76%, close to the worst unrealized of -1.09%, capturing essentially the bottom of what was available. Dominant factor: bad signal — the direction was simply wrong, and the exit near the worst point compounded it, but no exit timing would have saved a thesis that never materialized beyond a brief +0.80% blip. |
| GOOGL S4 | +7.01% | -0.29% | Signal: Right — GOOGL fell after entry and the short was never meaningfully underwater (worst unrealized just -0.29%). Timing: Fine — only -0.58% had moved by decision time and entry filled essentially at prior close, so the move was still ahead. Exit: The weak link — the trade banked ~+2.3% (+$15.74) while the position saw +7.01% unrealized at its best, so the fixed next-close exit gave back roughly two-thirds of the available move. Dominant factor: exit efficiency, not signal or timing. (Whether the regulatory news actually drove the drop isn't determinable from this data.) |
📖 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 ≥ 70.
