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 AMZN’s reaction history.
AMZN’s news landed in the pre-market window; the main session closed -0.42%.

- Pre-market4:00 – 9:30 AM

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.

The main-session result is measured upstream against the price at the news; the all-sessions result is computed here from its own anchor and close, so the two can differ in the last decimal. The adjusted column subtracts the S&P 500’s move over the same main-session span — there is no index anchor for the all-sessions span, so that cell stays empty rather than borrowing this one. After-hours and pre-market are measured upstream but populate on a small minority of events, so this page does not request them. Those rows are unmeasured, not empty.

Where this AMZN event came from, and what the tape did with it.
Amazon issued a press release, carried via Business Wire, on Nov 12, 2026. It was one of 3 Amazon headlines News Quantified labeled that day, so its measurement window overlaps with the others on a shared tape. The same session also carried Amazon's "AI Infrastructure Numbers Keep Climbing While the Week's Headlines…" and 1 other Amazon headline, each measured on its own clock.
Against the price at the news timestamp, AMZN'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 AMZN’s usual reaction.
Across 2,000+ labeled events, AMZN’s median 30-minute reaction to all news is -0.11% (46% up); by the close it is -0.04%.
| Middle 50% of AMZN reactions | -0.46% to +0.47% |
|---|---|
| Median reaction (30-min) | -0.11% |
| Measured reactions | 2,000+ |
Half of all Amazon news events land between -0.46% and +0.47% at 30 minutes; this one is a single draw from that distribution.

How the numbers are made.
How was AMZN's 5-minute reaction measured?
From the news timestamp, not the trading day: News Quantified takes the last trade before this press release 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 Amazon's median reaction, and how does this event compare?
Amazon's median is drawn from 2,000+ labeled events; at 30 minutes it sits at -0.11%, and -0.04% by the close. This event's move is one draw from that distribution — ordinary or outlier, the chart's median ticks show which.
3 Amazon headlines shared Nov 12, 2026. Whose reaction is this?
Each of the 3 same-day Amazon 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 Amazon's next reaction?
No. a measured reaction is a realized fact about Nov 12, 2026, not a forecast. Past reactions describe a distribution; they say nothing certain about any future move.
