What happened

SanDisk (SNDK) stock fell 5.3% to $1,330.05 on Thursday as a Samsung profit miss hit memory shares, and slipped further after solid results and an 8-for-1 split. The company then reported sales of $11.03 billion, up 23% from the last quarter and 378% from a year ago, beating analyst forecasts. It expects $12.2 billion to $12.6 billion next quarter, and each share will become eight on November 20. In after-hours trading the stock fell roughly 2% to 4%, with reports differing on the size.

Why it matters

SanDisk's fall shows that even a big earnings beat can leave a stock lower when investors already expected great news. The shares are up about 461% this year, so much of the AI-driven demand for storage chips was already in the price. The split does not change what the company is worth. It only cuts the price of each share, which can make buying small amounts easier.
