How the numbers are made.
How was MSFT's -0.21% 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 -1.38% 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.
Only one Microsoft headline was labeled Jun 5, 2026. How is it isolated?
It was the only Microsoft headline labeled that day, so its window has no same-day overlap — the move is measured cleanly from its own timestamp.
Does -1.38% predict Microsoft's next reaction?
No. -1.38% is a realized fact about Jun 5, 2026, not a forecast. Past reactions describe a distribution; they say nothing certain about any future move.
