Frequently Asked Questions
What is SNDK's after-hours price?
Sandisk (SNDK) is trading at $1630.08 after hours, down $3.27 (0.20%) from its regular-session close of $1633.35.
Why is SNDK moving after hours?
SNDK is down 0.20% 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 SNDK after-hours trading start and end?
After-hours trading in SNDK 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 SNDK's after-hours move hold at the open?
An after-hours move that carries into the next session becomes an opening gap, and SNDK's gap history is the best guide to what happens next: 58% of SNDK gap-ups have fully filled, and 88% 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.
