T. Rowe Price Small-Mid Cap ETF (TMSL) is trading at $41.50 after hours, up $0.01 (0.02%) from its regular-session close of $41.49.
TMSL is up 0.02% 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 TMSL on the ARCA 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.
