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 | +0.93% |
| D+2 | +3.19% |
| D+3 | +3.32% |
| D+4 | +2.61% |
| D+5 | +2.84% |
| 1M | +10.88% |
| 3M | +20.50% |
| 6M | +33.24% |
| 12M | +34.32% |
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, BAC had moved -0.30%; by the close it stood at +1.06% — the two readings disagree in direction, and the early move did not survive to the close.
Impact: Positive. Reaction = percent move vs. the price at the news timestamp. Sources below.
BAC’s news landed in the after-hours window; the main session closed +1.06%.

- 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. 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 BAC event came from, and what the tape did with it.
Bank of America filed Form S-8 with the SEC on Apr 30, 2025. It was one of 4 Bank of America headlines News Quantified labeled that day, so its measurement window overlaps with the others on a shared tape. The same session also carried Bank of America's "2025 Specialty Asset Management Outlook Released by Bank of America" and 2 other Bank of America headlines, each measured on its own clock.
Against the price at the news timestamp, BAC moved -0.30% after five minutes and +1.06% by the close — about 11.1× Bank of America's median close-day move of -0.10% 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 BAC's -0.30% reaction measured?
From the news timestamp, not the trading day: News Quantified takes the last trade before this SEC filing (Form S-8) as the base price and measures the move five minutes of trading later — point-in-time, zero look-ahead. The same clock produced the +1.06% to-close figure.
What is Bank of America's median reaction, and how does this event compare?
Bank of America's median is drawn from 2,000+ labeled events; at 30 minutes it sits at +0.04%, and -0.10% by the close. This event's move is one draw from that distribution — ordinary or outlier, the chart's median ticks show which.
4 Bank of America headlines shared Apr 30, 2025. Whose reaction is this?
Each of the 4 same-day Bank of America 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 +1.06% predict Bank of America's next reaction?
No. +1.06% is a realized fact about Apr 30, 2025, not a forecast. Past reactions describe a distribution; they say nothing certain about any future move.
