Reaction is being measured.
This event is recent. News Quantified labels the realized price reaction once the trading sessions after the news complete — point-in-time, with zero look-ahead. The measured move will appear here, and below in META’s reaction history.

Segment widths are fixed, so two events on different days sit in comparable places. Hatched segments are real elapsed time with no tape to measure — the overnight halt is not a gap in the data. This event carries no intraday receipt time, so it is not pinned to a minute.
Where this META event came from, and what the tape did with it.
Meta Platforms filed Form 8-K with the SEC on Oct 21, 2026. It was one of 2 Meta Platforms headlines News Quantified labeled that day, so its measurement window overlaps with the others on a shared tape. The same session also carried Meta Platforms's "Meta Reports Third Quarter 2026 Results", each measured on its own clock.
Against the price at the news timestamp, META's reaction is still being measured. Because several releases shared that day, their measurement windows overlap and no single headline cleanly owns the move.
How this compares to META’s usual reaction.
Across 2,000+ labeled events, META’s median 30-minute reaction to all news is +0.00% (50% up); by the close it is +0.06%.
| Middle 50% of META reactions | -0.58% to +0.56% |
|---|---|

How the numbers are made.
How was META's 5-minute reaction measured?
From the news timestamp, not the trading day: News Quantified takes the last trade before this SEC filing (Form 8-K) as the base price and measures the move five minutes of trading later — point-in-time, zero look-ahead. The same clock produced the to-close figure.
What is Meta Platforms's median reaction, and how does this event compare?
Meta Platforms's median is drawn from 2,000+ labeled events; at 30 minutes it sits at +0.00%, and +0.06% by the close. This event's move is one draw from that distribution — ordinary or outlier, the chart's median ticks show which.
2 Meta Platforms headlines shared Oct 21, 2026. Whose reaction is this?
Each of the 2 same-day Meta Platforms events is measured from its own timestamp, but their windows overlap on one tape, so we show the cluster rather than pretending a single headline owns the move.
Does a measured reaction predict Meta Platforms's next reaction?
No. a measured reaction is a realized fact about Oct 21, 2026, not a forecast. Past reactions describe a distribution; they say nothing certain about any future move.
