Frequently Asked Questions
What is BRK.B's after-hours price?
BERKSHIRE HATHAWAY (BRK.B) is trading at $510.50 after hours, up $0.13 (0.03%) from its regular-session close of $510.37.
Why is BRK.B moving after hours?
BRK.B is up 0.03% 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.
When does BRK.B after-hours trading start and end?
After-hours trading in BRK.B on the NYSE 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.
Will BRK.B's after-hours move hold at the open?
An after-hours move that carries into the next session becomes an opening gap, and BRK.B's gap history is the best guide to what happens next: 100% of gap-downs have filled over the past 5 years. Fill rates this high mean a large after-hours move is more often faded than extended.
