Roundhill ARM WeeklyPay ETF (ARMW) is trading at $37.56 after hours, up $0.13 (0.33%) from its regular-session close of $37.43.
ARMW is up 0.33% in after-hours trading. Moves in this session almost always follow something released after the 4:00 PM ET close — an earnings report, guidance, a filing, or news — and trade on far thinner volume than the regular session, so the size of the move can overstate what the market will settle on at the next open.
After-hours trading in ARMW on the BATS runs from 4:00 PM to 8:00 PM ET on trading days, immediately after the regular session closes. Not every broker offers the full window, and liquidity thins sharply after about 6:30 PM ET.
