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. 196 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 price series changes basis between the baseline close and the measured one, so the two prices do not describe the same shares of the same company and their ratio measures a corporate action, or a change in what the ticker identifies, rather than a move.

6 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 May 2026, the median decliner was 4.6% deeper below its pre-news close five sessions later; the largest catalyst group was Earnings, 54 of the 100 events, at a median of -29.8%.

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

Swipe the table sideways for the day +5 columns.

Catalyst Events Share of board Median move close to close Median at day +5 Still below the pre-news close at day +5
Earnings 54 54.0% -29.8% -32.1% 100.0% of 54
Other Announcement 16 16.0% -32.7% -35.1% 100.0% of 16
Offering / Dilution 10 10.0% -40.0% -49.4% 90.0% of 10
Clinical Trial Results 7 7.0% Fewer than 10 events in this group, so no figures are shown.
M&A / Acquisition 3 3.0% Fewer than 10 events in this group, so no figures are shown.

6 other catalyst types, 10 events: Contract / Partnership, Buyback / Dividend, Crypto & Treasury, Guidance Change, Uplisting / Compliance, Leadership Change.

How much of the drop held

Horizon Still below the pre-news close close to close Median change since the measured close as a share of the drop
Day +1 100.0% of 100 0.3% recovered, of 100
Day +5 98.0% of 100 4.6% deeper below baseline, of 100
Month end 93.9% of 99 3.6% recovered, of 99
Month end falls before day +5 for 15 of these 99 events, so this row is not a later horizon than the one above it. 99 of the 100 events have a month-end close later than the measured session; 1 has it on the measured session itself.

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 May 2026

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.
