Frequently Asked Questions
What is CLH's after-hours price?
Clean Harbors (CLH) is trading at $322.82 after hours, down $0.00 (0.00%) from its regular-session close of $322.82.
Why is CLH moving after hours?
CLH is down 0.00% 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 CLH after-hours trading start and end?
After-hours trading in CLH 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 CLH's after-hours move hold at the open?
An after-hours move that carries into the next session becomes an opening gap, and CLH's gap history is the best guide to what happens next: 67% of CLH gap-ups have fully filled, and 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.
When does CLH report earnings?
CLH is expected to report earnings around Nov 4, 2026 before the open (estimated), with an estimated EPS of $3.20. Earnings are the most common cause of a large after-hours move, since most companies report after the close.
