254 companies in the catalog currently match this technical screen. Leading the list, FTAI Aviation (FTAI) is opened 71.3% below the previous session's close (previous close 781.78), and had not traded back through it by the close.

What is a gap down?
A "gap" is the part of a move that happens while the market is shut, and a gap down is an opening price below the previous session's close: a company that closes at 100 and opens at 94 gapped down 6%, with no trade at any price in between. Gaps down are usually the market repricing news released out of hours — a profit warning, a failed trial, a lost contract — so they cluster around announcements rather than appearing at random.
How do I read the Gapped down at the open (3%+) screen?
This screen lists companies whose most recent session opened at least 3% below the previous close, largest gap first, and says whether price traded back up through that previous close before the session ended. About a third of gaps of 2% or more close again during the session that opened them, measured across our catalog, so the two facts are worth reading together. A gap down describes a session that has already opened; it is not a signal about the next one, and a large gap can equally reflect a real change in the business or an overreaction. Nothing here is advice.

Data: daily-close price history, recomputed nightly. Every figure is shown with its as-of date on the company page; a company without enough price history for this indicator is excluded, never estimated.
33 covered companies were not evaluated for this screen because their price series end on or before 2026-07-28 (AKTS, ANGX, CBC, CCRN, CPRX, ECHO, EEX, ESPR, FJET, FLY, FRMI, GEMI, and 21 more), at least 7 trading sessions behind the 2026-08-06 session the rest of the catalog carries. A technical signal is a claim about the present, so it is not asserted from a series that stops before it. Those companies keep the readings they have on their own page, with the as-of date they were computed from.
Last updated 2026-08-06 — this screen recomputes nightly from daily-close prices, so its members change over time.
