News from around the move

+8 more, from 7 outlets
How this is calculated
  • +5.3σ against global telecom companies (IXP): the close sat outside ±2.5σ of the residual over the last 60 trading days (σ = 2.17%).
  • Priced in US dollars on the NYSE; the country's own market had closed hours before this print.
  • The currency part (IDR against the dollar +0.3%, 1.0σ) and the company's part net of its sector and its currency (+11.2%, 5.3σ) are each tested at 2σ against their own 60 sessions. The currency is read at the European Central Bank's daily exchange rate (about 16:00 CET), so its last six hours before the close are not in it.
  • Searched: "Telkom Indonesia" OR Telkomsel OR "Jakarta stocks". The economy query is asked on every country move. 19 headlines came back. Left out of the 19 headlines the search returned: 7 from outlets that generate pages from price or filing data.
  • No company announcement was filed with the US regulator in the window (CIK 0001001807).
  • 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, for TLK and IXP alike: the first session both have a close. It grows by a session each day.
Unusual
The move left after subtracting global telecom companies (IXP)'s, 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.
Country
The business country the US regulator's filings give the company: Indonesia.
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.
