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 JNJ’s reaction history.
JNJ’s news landed in the after-hours window; the main session closed +0.22%.
- Mainprior session
- After-hours4:00 – 8:00 PM

- Pre-market4:00 – 9:30 AM
- Main session9:30 AM – 4:00 PM
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. This event carries no intraday receipt time, so it is not pinned to a minute.

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. 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 JNJ event came from, and what the tape did with it.
Johnson & Johnson issued a press release, carried via PR Newswire, on Oct 12, 2026. It was one of 2 Johnson & Johnson headlines News Quantified labeled that day, so its measurement window overlaps with the others on a shared tape. The same session also carried Johnson & Johnson's "TREMFYA® (guselkumab) demonstrated sustained clinical and endoscopic…", each measured on its own clock.
Against the price at the news timestamp, JNJ'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 JNJ’s usual reaction.
Across 2,000+ labeled events, JNJ’s median 30-minute reaction to all news is +0.06% (56% up); by the close it is +0.06%.
| Middle 50% of JNJ reactions | -0.26% to +0.39% |

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.
2 Johnson & Johnson headlines shared Oct 12, 2026. Whose reaction is this?
Each of the 2 same-day Johnson & Johnson 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 Johnson & Johnson's next reaction?
No. a measured reaction is a realized fact about Oct 12, 2026, not a forecast. Past reactions describe a distribution; they say nothing certain about any future move.
