🧭 Decisions
| strategy | ticker | action | side | rationale |
|---|---|---|---|---|
| S1 | MU | ○ skip | — | verdict FRESH, direction bearish -> short MU (other: Kioxia has halted NAND flash price hikes to prevent a demand slump in data centers, signaling potential relief for memory costs that have been rising sharply.) [skipped: signal conflict — wanted short, conflict-hold — mat 65 ties incumbent S1 long MU, incumbent held (strictly higher materiality required to flip)] → close -0.61% |
| S2 | - | ○ skip | — | no counterparty in universe |
| S3 | NVDA | ○ skip | — | direction unclear for NVDA → close -0.99% |
| S4 | MU | ● enter | ▼ short | overnight drift: short MU at close, exit next close (other: Kioxia has halted NAND flash price hikes to prevent a demand slump in data centers, signaling potential relief for memory costs that have been rising sharply.) |

Retrospectives
| ticker | mfe | mae | reflection |
|---|---|---|---|
| MU S4 | -0.02% | -6.67% | Signal (dominant factor): wrong direction. The short thesis — NAND price-hike relief pressuring MU — didn't play out; the stock rallied ~5.8% against the position, and the best unrealized was essentially zero (-0.02%), meaning the trade was never in the money at any point. Timing: No evidence of a stale move — price was roughly flat at entry (+0.23% since prior close), so the loss wasn't from chasing a move that had already happened. Exit: The mechanical next-close exit gave up -5.8% vs. a worst unrealized of -6.67%, so the exit was near the bottom of the range but there was nothing favorable to capture anyway. The loss is attributable almost entirely to a bad directional call, not execution. |
📖 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.
