|---|---|---|---|---|
| S1 | MU | ● enter | ▲ long | verdict REPRICING, direction bullish -> long MU (earnings: Costco reported strong Q4 earnings but highlighted that rising memory component costs are driving inflation in its electronics segment, signaling sustained high demand and pricing power for memory manufacturers.) |
| S2 | - | ○ skip | — | no counterparty in universe |
| S3 | AAPL | ○ skip | — | direction unclear for AAPL → close +1.40% |
| S4 | MU | ○ skip | — | overnight drift: long MU at close, exit next close (earnings: Costco reported strong Q4 earnings but highlighted that rising memory component costs are driving inflation in its electronics segment, signaling sustained high demand and pricing power for memory manufacturers.) [skipped at close: outranked — mat 65 long lost to mat 85 long (decision 22052) for S4 MU exiting 2026-09-28] |

Retrospectives
| ticker | mfe | mae | reflection |
|---|---|---|---|
| MU S1 | +0.93% | -2.15% | Signal: Wrong over the holding period — after entry the stock never rose more than +0.93% and fell as much as -2.15%, so the bullish repricing thesis didn't materialize in the window traded (whether it played out later isn't determinable from this data). Timing: Entry came after a +1.14% pop from prior close (fill at 1097.14 vs 1080.53 close), so the trade chased a move already underway and bought near the local high. Exit: The -1.29% realized loss sits between the +0.93% best and -2.15% worst unrealized — the exit gave back the modest available gain but also avoided the trough, so it was middling rather than the main problem. Dominant factor: signal failure, compounded by late entry — the price simply went the wrong way from a fill that was already elevated. |
📖 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.
