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 $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. On a board older than a year a fund is identified by its name alone, because an instrument class describes whoever holds the ticker today. 235 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, or carries a stored capitalization above $10 trillion, which is larger than any company has reached. Exclude the $5M to $25M band

3 events were 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.

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.

Company names are not shown on months older than a year, because only the current holder of each ticker is known.

In June 2025, the median gainer had given back 6.1% of its move five sessions later; the largest catalyst group was Other Announcement, 31 of the 100 events, at a median of +34.4%.

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
Other Announcement 31 31.0% +34.4% +29.4% of 30 90.0% of 30
Contract / Partnership 18 18.0% +38.2% +37.1% 88.9% of 18
M&A / Acquisition 11 11.0% +50.6% +50.2% 100.0% of 11
Earnings 11 11.0% +34.1% +21.4% 81.8% of 11
Clinical Trial Results 10 10.0% +56.5% +64.3% 100.0% of 10

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.

5 other catalyst types, 19 events: FDA & Regulatory, Offering / Dilution, Leadership Change, Buyback / Dividend, Crypto & Treasury.

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 12.6% given back, of 99
Day +5 91.9% of 99 6.1% given back, of 99
Month end 88.0% of 92 15.3% given back, of 92
Month end falls before day +5 for 17 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; 7 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.

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 June 2025

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

What the board was made of

Price before the move

Price bands are not shown on months older than a year, because the stored prices are adjusted for splits done since and a company that has reverse-split lands in a band its shares never traded in.

When the announcement landed

  • Pre-market71.0%
  • Intraday10.0%
  • After hours19.0%

Volume against normal

  • Under 5x6 events, 6.1%
  • 5x to 20x28 events, 28.6%
  • Over 20x64 events, 65.3%

2 events have too little trading history for a relative volume, and are not in the tiers above.

Industry

  • Pharmaceutical Preparations25 events, 25.0%
  • Surgical & Medical Instruments & Apparatus5 events, 5.0%
  • Biological Products, (no Diagnostic Substances)4 events, 4.0%
  • Biological Products, (no Disgnostic Substances)3 events, 3.0%
  • Finance Services3 events, 3.0%
  • Semiconductors & Related Devices3 events, 3.0%

32 other industries, 36 events

Industry not known: 21.0%

7 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 May 2025

100 events in the comparable window.

May 2025 median +50.0%, selected from the 11,039 events in that month's eligible pool

June 2025 median +42.2%, 7.8 points below May 2025. June 2025's median is taken over the 100 ranked rows, selected from the 7,297 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 on months older than a year, because only today's figure exists.

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. On a board older than a year a fund is identified by its name alone, because an instrument class describes whoever holds the ticker today.

On 100 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.
