Method and limits
The own move is how far NVDA went beyond its usual link to QQQ without NVDA itself (the coefficient over 250 sessions). The usual spread is the median over 120 sessions without report days; a case starts at 2σ. Neighbouring days of one story form an episode. All times are New York time. Sources: the Yahoo Finance news archive (headlines and publication times: Reuters, MT Newswires, Bloomberg and others), Hacker News, Wikipedia page views, Massive minute prices. Causes were set by hand from the headlines; AI search answers were not used as a source.
The small charts show the move beyond the market from the previous close: after hours of the day before, the night (dotted, no trading), the pre-market and the regular session (shaded).
- The archive has no WSJ, The Information or X: their scoops show through reprints, late (on 24 Nov 2025, 43 minutes after the price).
- Archive times are the declared publication times; the text is the article's current version.
- The Yahoo archive ends on 11 Sep 2026; NVDA had no large own moves from 3 Sep to 2 Oct 2026.
- The 2σ threshold and the robust spread are choices; another threshold changes the list.
