Gapped down at the open (3%+)
A technical stock screen computed nightly from daily-close price history (market data). Selection is deterministic — a company appears only when its stored indicator meets the screen's rule; nothing is estimated.
34 companies in the catalog currently match this technical screen. Leading the list is Resources Connection, Inc. (RGP): opened 18.2% below the previous session's close (previous close 3.74), 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.
38 covered companies were not evaluated for this screen because their price series end on or before 2026-10-05 (APGE, ATAI, BRR, CBC, CCRN, CPRX, CRNX, DBRG, DOMO, EA, ECHO, EEX, and 26 more), at least 3 trading sessions behind the 2026-10-08 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. 10 covered companies were not evaluated for this screen (AKTS, AVB, BRCC, HAWK, INHD, MVIS, NRDY, SHAZ, SOLS, TSEOQ) because our price history for these companies shows an unadjusted split or scale break. Every indicator read from such a series is an artifact of that break rather than a fact about the company, so none of them is asserted here — which is why the same companies have no 1-year return on their own page either.
Last updated 2026-10-08 — this screen recomputes nightly from daily-close prices, so its members change over time.
