How the numbers are made.

How was JNJ'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 Johnson & Johnson's median reaction, and how does this event compare?

Johnson & Johnson's median is drawn from 2,000+ labeled events; at 30 minutes it sits at +0.06%, 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.

Only one Johnson & Johnson headline was labeled Oct 24, 2026. How is it isolated?

It was the only Johnson & Johnson headline labeled that day, so its window has no same-day overlap — the move is measured cleanly from its own timestamp.

Does a measured reaction predict Johnson & Johnson's next reaction?

No. a measured reaction is a realized fact about Oct 24, 2026, not a forecast. Past reactions describe a distribution; they say nothing certain about any future move.
