Palantir shares rallied following announcements of a new partnership with Nvidia for secure government AI deployment and confirmation of its role in the Army's NGC2 modernization program.
overnight drift: buy PLTR at close, exit next close (partnership: Palantir shares rallied following announcements of a new partnership with Nvidia for secure government AI deployment and confirmation of its role in the Army's NGC2 modernization program.)
The thesis worked as intended: catalyst-driven overnight drift on partnership news delivered +2.2%, capturing most of the +3.25% peak with tolerable -1.78% adverse excursion. That said, the entry rule fired on already-stale news — PLTR "rallied following announcements," meaning the pop was partially priced in at entry and the trade rode residual momentum rather than the catalyst itself. Concrete improvement: require the news to break after the prior close (or within N hours of entry) and add a filter rejecting entries when the stock is already up more than ~3% intraday on the same headline, since chasing extended moves shrinks the edge and fattens the left tail.

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.
