Gapped up 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.
25 companies in the catalog currently match this technical screen. Leading the list is PACIRA BIOSCIENCES INC (PCRX): opened 44.1% above the previous session's close (previous close 25.2), and had not traded back through it by the close.

What is a gap up?
A "gap" is the part of a move that happens while the market is shut. The overnight gap is simply the opening price measured against the previous session's closing price: if a company closes at 100 and opens at 105, it gapped up 5%, and no trade happened anywhere in between. Gaps are usually the market repricing something that was announced out of hours — results, a trial readout, a bid — which is why they cluster around earnings dates rather than appearing at random.
How do I read the “Gapped up at the open (3%+)” screen?
This screen lists companies whose most recent session opened at least 3% above the previous close, largest gap first, and says whether price traded back down through that previous close before the session ended. That second fact matters more than it looks: measured across our catalog, about a third of gaps of 2% or more are closed again during the very session that opened them. A gap describes a session that has already opened. It is not a signal, it says nothing about the next session, and 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.
