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 | +0.28% |
| D+2 | -0.35% |
| D+3 | +0.59% |
| D+4 | -5.14% |

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, AMD had moved +0.94%; by the close it stood at -0.33% — 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.
AMD’s news landed in the pre-market window; the main session closed -0.33%.
- Mainprior session

- Overnightno tape
- 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.

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.

Where this AMD event came from, and what the tape did with it.
Advanced Micro Devices issued a press release, carried via PR Web, on May 12, 2026. It was one of 2 Advanced Micro Devices headlines News Quantified labeled that day, so its measurement window overlaps with the others on a shared tape. The same session also carried Advanced Micro Devices's "Form 13F-HR ADVANCED MICRO DEVICES For: Mar 31", each measured on its own clock.
Against the price at the news timestamp, AMD moved +0.94% after five minutes and -0.33% by the close — about 0.5× Advanced Micro Devices's median close-day move of +0.70% 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 AMD's +0.94% 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 -0.33% to-close figure.
What is Advanced Micro Devices's median reaction, and how does this event compare?
Advanced Micro Devices's median is drawn from 2,000+ labeled events; at 30 minutes it sits at +0.06%, and +0.70% by the close. This event's move is one draw from that distribution — ordinary or outlier, the chart's median ticks show which.
2 Advanced Micro Devices headlines shared May 12, 2026. Whose reaction is this?
Each of the 2 same-day Advanced Micro Devices 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 -0.33% predict Advanced Micro Devices's next reaction?
No. -0.33% is a realized fact about May 12, 2026, not a forecast. Past reactions describe a distribution; they say nothing certain about any future move.
