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.

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 $5M or more, measured today, including the $5M to $25M band. 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. 34 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. Exclude the $5M to $25M band

1 event was left out of this board because the ticker trades over the counter rather than on NYSE or Nasdaq, and no announcement naming it alone has ever recorded a listed exchange.

20 rows print a move recomputed from the session's own closing prices, because the stored figure disagreed with them; each says so on the row, and each keeps the rank the stored figure gave it.

4 rows withhold a market cap because the vendor's stored figure disagrees with the share count and price it is derived from by more than a factor of three, counting the filed all-class share count where one exists.

In September 2026 through 2026-09-22 (15 of the month's 15 completed sessions measured), the median gainer had given back 30.2% of its move five sessions later; the largest catalyst group was Other Announcement, 44 of the 100 events, at a median of +26.6%.

Contract / Partnership 15 15.0% +27.8% Only 8 of these 15 events have a five-session follow-up, so no median is shown. Only 8 of these 15 events have a five-session follow-up, so no share is shown.

M&A / Acquisition 5 5.0% 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.

6 other catalyst types, 15 events: Offering / Dilution, Buyback / Dividend, Crypto & Treasury, Leadership Change, Reverse Merger / Shell, Guidance Change.

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 98.9% of 93 5.7% given back, of 93
Day +5 84.6% of 65 30.2% given back, of 65
Month end Not shown until September 2026 closes.

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 September 2026

Two or more ranked moves this month, each on a different trading day.

Against August 2026

Both months ranked over their first 15 trading sessions.

100 events in the comparable window.

August 2026 median +36.3%, selected from the 6,670 events in that month's eligible pool

September 2026 median +27.7%, 8.6 points below August 2026. September 2026's median is taken over the 100 ranked rows, selected from the 5,261 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.

Market cap is not shown because the stored figure disagrees with the share count and price it is derived from.

NYSE and Nasdaq companies with a market capitalization of $5M or more, measured today, including the $5M to $25M band. 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.

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