verdict FRESH, direction bullish -> long PLTR (partnership: Palantir Technologies announced a partnership with Nebius Group to designate it as a preferred sovereign AI infrastructure provider, integrating Nebius' cloud services into Palantir's commercial perimeter.)
overnight drift: long PLTR at close, exit next close (partnership: Palantir Technologies announced a partnership with Nebius Group to designate it as a preferred sovereign AI infrastructure provider, integrating Nebius' cloud services into Palantir's commercial perimeter.)
Signal: correct — the bullish call played out, with the trade closing +1.51% and minimal adverse excursion (-0.42%). Timing: entry was not chasing; price was only +0.49% off the prior close (and entry filled slightly below it), so the move had not already happened. Exit: solid capture — +$13.10 (+1.51%) against a best unrealized of +2.24%, so roughly two-thirds of the available move was banked. Dominant factor: a correct signal executed cleanly; nothing in the data points to a timing or exit problem.
Signal was directionally right but barely: the trade closed +0.38%, a small fraction of the +3.20% available at the best point, while enduring a -7.38% drawdown along the way — the mechanical next-close exit landed near flat on what was a very volatile ride. Timing worked against it: the fill at 176.51 was ~1.2% above the prior close versus the +0.49% known at decision time, so a chunk of the overnight drift was already paid at entry. The dominant factor is exit capture: the fixed exit gave up nearly all of the peak move, though whether the news itself drove the intraday swing (versus broader PLTR volatility) can't be settled from this data.

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.
