Frequently Asked Questions
What is SNPS's after-hours price?
Synopsys (SNPS) is trading at $490.02 after hours, up $0.13 (0.03%) from its regular-session close of $489.90.
Why is SNPS moving after hours?
SNPS 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 SNPS after-hours trading start and end?
After-hours trading in SNPS on the NASDAQ 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 SNPS's after-hours move hold at the open?
An after-hours move that carries into the next session becomes an opening gap, and SNPS's gap history is the best guide to what happens next: 73% of SNPS gap-ups have fully filled, and 60% 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 SNPS report earnings?
SNPS is expected to report earnings around Dec 9, 2026 after the close (estimated), with an estimated EPS of $4.10. Earnings are the most common cause of a large after-hours move, since most companies report after the close.
