🧭 Decisions

|---|---|---|---|---|
| S1 | MU | ○ skip | — | verdict FRESH, direction bullish -> long MU (product: Samsung demonstrated its LPDDR5X-PIM memory chip which integrates AI compute into DRAM to triple inference speed and reduce costs, signaling a competitive shift in the AI memory market relevant to Micron.) [skipped: duplicate theme — already holding S1 long MU exiting 2026-08-26] → close -0.69% |
| S2 | - | ○ skip | — | no counterparty in universe |
| S3 | NVDA | ○ skip | — | direction unclear for NVDA → close -0.79% |
| S4 | MU | ● enter | ▲ long | overnight drift: long MU at close, exit next close (product: Samsung demonstrated its LPDDR5X-PIM memory chip which integrates AI compute into DRAM to triple inference speed and reduce costs, signaling a competitive shift in the AI memory market relevant to Micron.) |

Retrospectives
| ticker | mfe | mae | reflection |
|---|---|---|---|
| MU S4 | +5.18% | -2.92% | Signal: Ambiguous on merits — the cited news (a Samsung competitive advance) reads as bearish for Micron, yet the strategy went long; the data here can't settle whether the drift thesis was sound, only that close-to-close the direction was slightly wrong (-0.22%). Timing: Entry came after a modest +0.89% run from the prior close (entry 934.8 vs. 932.97), so a small part of any move was already priced in, but not enough to be decisive. Exit: This is the dominant factor. The position was up as much as +5.18% while open (~+48 USD unrealized) but the fixed next-close exit surrendered essentially all of it, closing at -2.07 USD. The trade had substantial favorable movement available and the mechanical exit captured none of it. |
📖 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.
