The announcement, and the market’s answer.
Amazon filed Form 13F-HR with the SEC on Aug 6, 2026. It was one of 2 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 "Form N-PX AMAZON COM INC For: Jun 30", each measured on its own clock.
Against the price at the news timestamp, AMZN moved +1.56% after five minutes and +0.63% by the close — about 17.6× Amazon's median close-day move of -0.04% across 2,000+ events.

How the numbers are made.
How was AMZN's +1.56% reaction measured?
From the news timestamp, not the trading day: News Quantified takes the last trade before this SEC filing (Form 13F-HR) as the base price and measures the move five minutes of trading later — point-in-time, zero look-ahead. The same clock produced the +0.63% 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.
2 Amazon headlines shared Aug 6, 2026. Whose reaction is this?
Each of the 2 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 +0.63% predict Amazon's next reaction?
No. +0.63% is a realized fact about Aug 6, 2026, not a forecast. Past reactions describe a distribution; they say nothing certain about any future move.
