STOCK TITAN

October 2026 Stock Losers on News, Micro Caps Included

Ranked by the close-to-close change of the trading session each announcement landed in. How this is measured.

Month to date, October 2026.

Data through the session. 15 of 16 completed market sessions produced ranked moves. The market has traded since the last measured session. That date is the last ranked session, not the last priced one, so follow-through dates run later.

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. 76 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.

1 event was left out of this board because the measured session changed hands for less than $25,000 in total, so the percentage prices a handful of shares rather than a move anyone could have taken.

9 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 October 2026 through October 21 (15 of the month's 16 completed sessions measured), the median decliner’s drop was 33.8% larger five sessions later; the largest named catalyst was M&A / Acquisition, 12 of the 100 events, at a median of -17.4%, and 27 events fit no named group.

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, 30 events: Offering / Dilution, Contract / Partnership, Leadership Change, Listing / Compliance, Crypto & Treasury, Reverse Merger / Shell, FDA & Regulatory.

How much of the drop held

Horizon Still below the pre-news close (close-to-close basis) Median change since the measured close as a share of the drop
Day +1 94.9% of 99 6.5% larger drop, of 99
Day +5 98.7% of 77 33.8% larger drop, of 77
Month end Not shown until October 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 October 2026

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

Against September 2026

Both months ranked over their first 15 trading sessions.

100 events from September 2026 in the comparable window.

September 2026 median -18.2%, selected from the 4,837 events in that month's eligible pool.

October 2026 median -18.4%, 0.2 points steeper than September 2026. October 2026's median is taken over the 100 ranked rows, selected from the 5,371 events in that month's eligible pool.

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.

Market cap is not shown because the two figures our data vendors report for it are 10 times or more apart, and we cannot tell which one is right.

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.
