A hatched rung is a threshold the price never touched inside the measured window — not a missing measurement. Most news never moves a large-cap by 5% either way, so a mostly empty ladder is the finding, not a gap in the data.
| Held for | Return |
|---|---|
| D+1 | +0.60% |
| D+2 | +0.51% |
| D+3 | +1.11% |
| D+4 | +1.20% |
| D+5 | +2.76% |
| 1M | -2.64% |
| 3M | -10.91% |
| 6M | -6.07% |
| 12M | +18.79% |
Each row is measured from the price at the news to that horizon independently, so the ladder is not cumulative and a later row can sit above an earlier one. “Available” is a date, not a gap: that horizon has not elapsed yet for this event, and it is computed from the event’s own timestamp rather than from the data. An em dash is the other case — the horizon passed and no return was recorded.
Five minutes after the news, JNJ had moved -0.08%; by the close it stood at +0.46% — the two readings disagree in direction, and the early move did not survive to the close.
Impact: Neutral. Reaction = percent move vs. the price at the news timestamp. Sources below.
JNJ’s news landed in the pre-market window; the main session closed +0.46%.

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.

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. The adjusted column subtracts the S&P 500’s move over the same main-session span — there is no index anchor for the all-sessions span, so that cell stays empty rather than borrowing this one. 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.

How the numbers are made.
How was JNJ's -0.08% 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 +0.46% 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 9, 2024. 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 +0.46% predict Johnson & Johnson's next reaction?
No. +0.46% is a realized fact about Oct 9, 2024, not a forecast. Past reactions describe a distribution; they say nothing certain about any future move.
