About after-hours movers

After-hours (post-market) trading runs from 4:00 p.m. until 8:00 p.m. ET. It's when most companies report quarterly earnings, so the after-hours leaderboard is dominated by earnings reactions — a beat-and-raise rocketing higher, a miss or weak guidance getting sold off. It's the first place you see how the market is digesting results that just dropped.

Like the premarket, after-hours volume is thin, so moves are exaggerated and can look very different by the next morning. An earnings pop that fades on the conference-call guidance, or a sell-off that recovers once analysts weigh in, is common. The after-hours list is most useful for building tomorrow's gap watchlist — flagging the names that will open with a gap and the catalysts behind them — rather than for chasing the move at 6 p.m.

These names roll straight into the next premarket session, so tracking them after-hours gives you a head start. StockSetups runs its alert engine and Top Lists through the post-market session in real time; this public snapshot is delayed, and the live boards are inside the app.

Frequently asked

What are after-hours movers?

Stocks making the biggest percentage moves during after-hours (post-market) trading, 4:00–8:00 p.m. ET. Most are reacting to earnings reports released after the close, plus any breaking corporate news.

Why do most earnings moves happen after hours?

Companies typically release quarterly results after the 4:00 p.m. close to give the market time to digest them before the next open. That's why the after-hours list is dominated by big earnings reactions — beats, misses and guidance changes.

Do after-hours moves carry into the next day?

Often, but not always. After-hours volume is light, so a move can extend, fade or reverse by the next morning once full liquidity returns. The after-hours list is best used to build a gap watchlist for the next premarket and regular session.
