The announcement, and the market’s answer.
Microsoft issued a press release, carried via ACCESS Newswire, on Jun 29, 2026. It was one of 3 Microsoft headlines News Quantified labeled that day, so its measurement window overlaps with the others on a shared tape. The same session also carried Microsoft's "Candy Crush Turns NYC Into One Big Pregame with Free Candy Cabs for…" and 1 other Microsoft headline, each measured on its own clock.
Against the price at the news timestamp, MSFT moved -0.06% after five minutes and +0.09% by the close — about 0.8× Microsoft's median close-day move of -0.11% across 2,000+ events. Because several releases shared that day, their measurement windows overlap and no single headline cleanly owns the move.

How the numbers are made.
How was MSFT's -0.06% 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 +0.09% to-close figure.
What is Microsoft's median reaction, and how does this event compare?
Microsoft's median is drawn from 2,000+ labeled events; at 30 minutes it sits at +0.02%, and -0.11% by the close. This event's move is one draw from that distribution — ordinary or outlier, the chart's median ticks show which.
3 Microsoft headlines shared Jun 29, 2026. Whose reaction is this?
Each of the 3 same-day Microsoft 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 +0.09% predict Microsoft's next reaction?
No. +0.09% is a realized fact about Jun 29, 2026, not a forecast. Past reactions describe a distribution; they say nothing certain about any future move.
