Retrospectives

ticker	mfe	mae	reflection
AAPL S1	+0.45%	-1.10%	Signal: Wrong over the holding period — the short only ever went +0.45% in the money while moving as much as −1.10% against, and it exited underwater. Whether the bearish repricing thesis would have played out on a longer horizon can't be settled here, since the exit wasn't signal-driven. Timing: Not a case of chasing a move that already happened — the stock had risen +1.01% into entry, so the short was entered before any bearish move, at an arguably favorable price for the thesis; the move simply never came. Exit: The close was mechanical (netted out by a conflicting long-AAPL decision), not a judgment on the trade. The −0.12% realized loss sits between the +0.45% best and −1.10% worst, so the forced exit neither captured the small gain available nor took the full drawdown. Dominant factor: a signal that didn't materialize, compounded by an exit dictated by an internal conflict rather than the trade's own logic — meaning this trade never got a clean test of its thesis.

📖 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.
