Retrospectives

ticker	mfe	mae	reflection
AAPL S1	+1.34%	-0.34%	Retro note: The entry logic treated a speculative regulatory headline (lawmakers urging action, not action taken) as FRESH bearish catalyst, but the market shrugged — the trade closed flat (-$0.04) despite the thesis. Notably, the position was up +1.34% unrealized at its best, so the real failure was exit management, not direction: the edge existed briefly and was given back entirely. Improvement: Either (a) tighten the entry rule to require enacted or imminent regulatory action rather than legislative jawboning (downgrade "urging/proposing" headlines to STALE or low-conviction), or (b) if soft-catalyst trades stay in scope, add a take-profit or trailing stop around +1% since these headline fades decay fast and won't trend.
MU S3	+6.09%	-0.16%	The entry thesis was sound and the timing was excellent — max drawdown was only -0.16% while the position ran to +6.09% unrealized — but you banked just +0.47%, capturing under a tenth of the available move. The problem isn't the REPRICING verdict; it's that regulatory repricing catalysts (a structural demand shift toward MU) play out over days/weeks, and this trade was managed like a scalp. Concrete fix: when the verdict is REPRICING (vs. a transient headline), attach a minimum hold horizon or a trailing stop instead of a fixed take-profit, so the exit logic matches the multi-day nature of the catalyst the entry rule is keying on. (Also flag for the retro: MU entry price of $850 doesn't match reality — verify the data feed before trusting these fills.)

📖 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.
