ASML faces a new competitive threat from a Chinese government-backed company manufacturing its own DUV lithography systems, potentially impacting future sales in the Chinese market.
verdict FRESH, direction bearish -> short ASML (regulatory: ASML faces a new competitive threat from a Chinese government-backed company manufacturing its own DUV lithography systems, potentially impacting future sales in the Chinese market.)
overnight drift: short ASML at close, exit next close (regulatory: ASML faces a new competitive threat from a Chinese government-backed company manufacturing its own DUV lithography systems, potentially impacting future sales in the Chinese market.)
Signal: Correct — the bearish call played out, with price falling from 1748.63 to 1737.15. The move had not already happened at entry (price was only +0.52% since prev close and flat over the last 30 minutes), so timing wasn't stale. Exit: Essentially perfect within the observed window — the +11.48 P&L (~+0.66%) matches the best unrealized of +0.66%, meaning the exit captured all of what was available while the trade was open. The dominant factor here is a correct signal cleanly harvested; the only caveat is the move itself was small (~0.7%), and this data can't tell us whether the regulatory thesis drove the decline or it was noise.
Signal was wrong: the rationale predicted downside from the Chinese DUV competitive threat, but ASML rose ~3.4% against the short position. Timing wasn't the issue — the stock was only +0.52% since prior close at entry, so there's no evidence the anticipated move had already occurred; the predicted move simply never came. The exit captured close to the worst available outcome (-3.44% realized vs. best +0.23% / worst -4.64%), but with a max favorable excursion of just +0.23%, there was essentially nothing to capture — the dominant factor is a flat-out wrong directional signal.

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.
