Skip the ranked rows and go to the month summary

Every percentage on a row, the follow-through readings included, is measured against that row's own pre-news close, which the row names. A day +5 reading is therefore the move from before the announcement, not a further change on top of the headline percentage.

NYSE and Nasdaq companies with a market capitalization of $25M or more, measured today. The exchange is the one recorded on each announcement, and a release naming several tickers records one venue for all of them. A session that changed hands for less than $25,000 in total is not ranked, because a percentage set by a handful of shares is a print rather than a move. 692 smaller events this month are held out of this month's eligible pool; switch to include them. 395 events never entered this month's eligible pool, because the ticker is a warrant, a unit, a right or a preferred rather than common stock, is classed today as a fund, a trust or an index product, or carries a stored capitalization above $10 trillion, which is larger than any company has reached. Include the $5M to $25M band

On 2 of these rows the measured session was reconstructed from the announcement time, because it predates our stored session records.

1 event was left out of this board because the vendor names the ticker as a preferred, a note, a depositary share or a fund rather than a company's common stock.

2 events were left out of this board because the ticker had not traded for more than 10 days before the measured session, so no comparable prior close exists.

In December 2025, the median gainer had given back 12.8% of its move five sessions later; the largest catalyst group was Other Announcement, 25 of the 100 events, at a median of +27.8%.

How much of the move survived

Horizon	Still above the pre-news close close to close	Median change since the measured close as a share of the move
Day +1	97.0% of 100	6.0% given back, of 100
Day +5	86.9% of 99	12.8% given back, of 99
Month end	84.2% of 95	17.4% given back, of 95
Month end falls before day +5 for 11 of these 95 events, so this row is not a later horizon than the one above it. 95 of the 100 events have a month-end close later than the measured session; 3 have it on the measured session itself, and 2 have no month-end close.

Both figures in a row are measured over the events that have a close at that horizon, the count printed beside each of them, not over all 100 events on this board, which is why the denominators differ between rows.

Repeat runners

Some companies move on news more than once. The left list holds the ones that moved twice or more this month; the right list holds the ones that also moved in the months before it. The ranking above shows one row per move, so a name that keeps coming back is only visible here.

Moved twice or more inside December 2025

What the board was made of

Price before the move

When the announcement landed

Volume against normal

1 event has too little trading history for a relative volume, and is not in the tiers above.

Industry

38 other industries, 45 events

Industry not known: 14.0%

Against November 2025

100 events in the comparable window.

November 2025 median +32.5%, selected from the 9,016 events in that month's eligible pool

December 2025 median +28.9%, 3.6 points below November 2025. December 2025's median is taken over the 100 ranked rows, selected from the 6,219 events in that month's eligible pool.

The two windows drew on pools of very different size, so part of the gap between the medians is how deep into each pool the top hundred reaches rather than how severe the moves were.

How this ranking is measured

Close-to-close change on the measured trading session, against the previous close.

An announcement before 16:00 ET is measured on that trading day; one at or after 16:00 ET, or on a weekend, is measured on the next trading day.
One row per company and measured session. Other announcements the company made in the same session are listed inside the row.
A ranking is a coincidence of news and price on the same session, not proof that the news caused the move. Part of an intraday move can precede the announcement.
No Stated Cause marks a release in which the company itself says it knows of no reason for the move, while Other Announcement marks a release these rules could not classify.

Eligibility uses each company's capitalization today, not its capitalization at the time. Archive boards can therefore change as companies grow or shrink.

Prices are adjusted for stock splits the company has done since, so an older row's dollar figures are stated on today's share count and are not the prices that traded that day. The percentage move, the dollar volume and the relative volume are unaffected, because both prices carry the same adjustment. The session's share count carries the adjustment too, so the shares figure beside the dollar volume is that count restated on today's basis rather than the number of shares that changed hands. Where the ticker was retired the price series stops with it and no later adjustment reached it, so those rows are marked as traded and their dollars are the ones that changed hands on the day.

On 2 of these rows the measured session was reconstructed from the announcement time, because it predates our stored session records.

This archive starts at 2020-04, the first month with ranked moves.
