How this is calculated
  • +4.3σ against its own history, since it has no sector fund to measure against: the close sat outside ±2.5σ of the residual over the last 60 trading days (σ = 1.23%).
  • A global name: its move is about the world rather than about America, and it has no home currency.
  • A global name has no home currency, so its move is not split.
  • Searched: Apple (China OR Foxconn OR tariffs OR "supply chain"). The economy query is asked on every country move. 66 headlines came back. Left out of the 66 headlines the search returned: 4 from outlets that generate pages from price or filing data, 3 repeated.
  • No company announcement was filed with the US regulator in the window (CIK 0000320193).
  • Every outlet is listed, never one headline: the query returns many outlets for one story, and choosing one would be ranking. Each item's own time decides whether it came before or after the close.
  • Links go via Google News. Fetched at the close and once more after the next close.
How this is calculated
Price
Finnhub's live trades in US hours, one tick per second; the daily bar from one quote at 16:15 New York, with open, high, low and close but no volume.
Chart
Daily closes as stored, each divided by the close on 1 Jul and multiplied by 100: the first session it has a close. It grows by a session each day.
Unusual
Not measured against a sector fund: against IXN its residual was 1.5x noisier than its raw return (beta 0.02), so the raw return is used. The company's own move is measured against the last 60 trading days (σ) and recomputed nightly. A close beyond 2.5σ is an unusual move; beyond 5σ, an extremely unusual one.
Sessions
Every session from 16 Oct has been checked. The bars begin earlier, backfilled from the same feed, but nothing before that date was tested, so the count does not reach back past it.
Currency
Where the European Central Bank publishes the country's exchange rate, the same day's rate separates the currency's move from the stock's; where it does not, the move says why.
News
Fetched because the move was unusual, never on a timer; every outlet that names the subject is kept, split at the close.
