Frequently Asked Questions
What is OMC's after-hours price?
Omnicom (OMC) is trading at $79.00 after hours, down $0.01 (0.01%) from its regular-session close of $79.01.
Why is OMC moving after hours?
OMC is down 0.01% 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 OMC after-hours trading start and end?
After-hours trading in OMC 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 OMC's after-hours move hold at the open?
An after-hours move that carries into the next session becomes an opening gap, and OMC's gap history is the best guide to what happens next: 67% of OMC gap-ups have fully filled, and 67% 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.
When does OMC report earnings?
OMC is scheduled to report earnings on Oct 20, 2026 after the close (confirmed), with an estimated EPS of $2.59. Earnings are the most common cause of a large after-hours move, since most companies report after the close.
