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.

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. 786 smaller events this month are held out of this month's eligible pool; switch to include them. 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. Include the $5M to $25M band
1 row withholds 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.

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 | 3.1% recovered, of 100 |
| Day +5 | 99.0% of 100 | 0.8% deeper below baseline, of 100 |
| Month end | 90.8% of 98 | 5.9% recovered, of 98 |
| Month end falls before day +5 for 9 of these 98 events, so this row is not a later horizon than the one above it. 98 of the 100 events have a month-end close later than the measured session; 2 have 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.

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.
