NYSE and Nasdaq companies with a market capitalization of $25M or more, measured today. 786 smaller events are excluded; switch to include them. 120 events are excluded because the ticker is classed today as a fund, a trust or an index product, or carries a capitalization no company has. Include the $5M to $25M band

In May 2026, the median gainer had given back 11.5% of its move five sessions later; the largest catalyst group was Earnings, 47 of the 100 events, at a median of +38.9%.

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

Which catalysts drove the board

Swipe the table sideways for the day +5 columns.

Catalyst Events Share of board Median move close to close Median at day +5 Still above the pre-news close at day +5
Earnings 47 47.0% +38.9% +42.4% 97.9% of 47
Other Announcement 22 22.0% +38.1% +18.3% of 21 71.4% of 21
M&A / Acquisition 9 9.0% Fewer than 10 events in this group, so no figures are shown.
Contract / Partnership 7 7.0% Fewer than 10 events in this group, so no figures are shown.
Offering / Dilution 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.

7 other catalyst types, 10 events: FDA & Regulatory, Clinical Trial Results, Guidance Change, Uplisting / Compliance, Buyback / Dividend, Crypto & Treasury, Leadership 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 99.0% of 99 0.0% given back, of 99
Day +5 92.9% of 99 11.5% given back, of 99
Month end 87.0% of 92 1.4% further above baseline, of 92
Month end falls before day +5 for 11 of these 92 events, so this row is not a later horizon than the one above it. 92 of the 100 events have a month-end close later than the measured session; 6 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.

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.

Market cap is not shown on months older than a year, because only today's figure exists.

NYSE and Nasdaq companies with a market capitalization of $25M or more, measured today.
