For this session, the closing half hour, including the auction print, carry 25.1% of the whole day's volume. The 12:30-to-1:00 lunchtime half hour carry 3.5%, while the opening half hour carry 8.1%. The heavy close get one mechanical reason: index funds, mutual funds, and benchmarked institutions dey trade at official closing prices, and their orders dey gather for the closing auction. Altogether, volume land inside 32 separate half-hour buckets across the extended day.

Wetin be premarket and after-hours trading?

Premarket (4:00 a.m. to 9:30 a.m. ET) and after-hours (4:00 p.m. to 8:00 p.m. ET) na electronic-only trading windows wey surround the regular trading day. Fewer participants dey show for there, bid-ask spreads dey wider, and most brokers dey accept only limit orders for these sessions. Company news dey pile up for these periods. Earnings releases dey mostly come just after the 4:00 p.m. close and during the hours before market open. Na for these windows stock price fit gap far from the previous close. Price wey print for 7:00 p.m. no guarantee where the stock go open the next morning.

Session-by-session volume shares, measured bid-ask spread costs, and the exact time wey headlines actually land dey inside after-hours and premarket trading, wey be the companion piece to this page. The short version, as the panels above show: extended sessions dey real and traders fit trade them, but volume for there dey thin compared with the regular day.

Options and futures dey trade for which hours?

Options on individual companies dey trade from 9:30 a.m. to 4:00 p.m. ET. Dem no dey trade for premarket or after-hours. Options on small list of broad-market ETFs and index products, like SPY, QQQ and IWM, plus index options like SPX and VIX, get extra 15 minutes. Dem fit trade reach 4:15 p.m. ET.
