Overnight stock movers: 8 PM to 4 AM ET

Answer

What are the biggest overnight stock movers?

Overnight stock movers are US stocks making the biggest percentage moves in the overnight session, which runs 8:00 PM to 4:00 AM ET. Tapeboard ranks the overnight tape by percent change versus the prior regular-session close; the session is thinnest in the middle of the night and firms up as foreign desks open. See the live overnight board with the full methodology at tapeboard.com/movers/overnight. Free tier: top 3 rows live, the rest 15-minute delayed; real-time on the free Pro trial.

The Blue Ocean ATS overnight session, 8 PM to 4 AM ET, is the single most underused information source in retail trading. Foreign desks digest US earnings prints there, and by the time pre-market opens at 4 AM the move is already in the tape.
