100 ranked gains in October 2025
Skip the ranked rows and go to the month summaryEvery 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.
Rows are ordered by the move measured when the board was ranked. A percentage recomputed from the session's own closing prices can sit a little above or below its neighbours; the rank is the one the measured move gave the row.

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. 823 smaller events this month are held out of this month's eligible pool; switch to include them. 419 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.
Whole board, unfiltered
In October 2025, the median gainer had given back 17.7% of its move five sessions later; the largest catalyst group was Other Announcement, 32 of the 100 events, at a median of +34.3%.

| M&A / Acquisition | 9 | 9.0% | Fewer than 10 events in this group, so no figures are shown. | ||
The day +5 figures are measured over the events in each group that have a five-session close, the count printed beside them, not over every event in the group.
7 other catalyst types, 18 events: FDA & Regulatory, Offering / Dilution, Crypto & Treasury, Guidance Change, Leadership Change, Uplisting / Compliance, Buyback / Dividend.
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 | 100.0% of 100 | 5.6% given back, of 100 |
| Day +5 | 93.9% of 99 | 17.7% given back, of 99 |
| Month end | 82.1% of 95 | 22.8% given back, of 95 |
| Month end falls before day +5 for 14 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; 4 have it on the measured session itself, and 1 has 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.

What the board was made of
Price before the move
When the announcement landed
Volume against normal
6 events have too little trading history for a relative volume, and are not in the tiers above.
Industry
31 other industries, 39 events
Industry not known: 22.0%
3 events on this board carry the flag for a move that ran against its own release, too few to say whether the flag predicts anything.
Against September 2025
100 events in the comparable window.
September 2025 median +36.1%, selected from the 7,131 events in that month's eligible pool
October 2025 median +35.9%, 0.2 points below September 2025. October 2025's median is taken over the 100 ranked rows, selected from the 10,334 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.
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.
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.
