What happened to SanDisk

SanDisk was under heavy selling pressure on Thursday, 5 November 2026, with reports showing the stock down roughly 17% to 20% during the session. One Nasdaq reading put it at $834.91, down 19.52% at 12:54 p.m. ET.

The move is why SNDK is trending in Singapore today. The overnight US drop is the main news, and it is relevant to Singapore investors who track Wall Street before or during local trading hours.

Why investors are selling

The decline is part of a broader two-day selloff in AI-linked semiconductor and memory shares. Investors are reassessing both data-centre spending and memory prices.

The selling also spread to peers: Micron was down about 5%, and Western Digital was also reported down about 5% in morning trading.

The bigger SanDisk picture

Despite the recent drop, one market commentary said SanDisk was still up about 444% over the previous year as of 4 November 2026. It also said the stock had fallen about 47% since the beginning of July.

That mix of a long-term rally and a sharp recent retreat is why some traders are debating whether the stock is a bargain or a value trap.

What to watch next

Watch whether SanDisk stabilises after the 5 November selloff or whether the weakness continues with the broader memory group. If peers keep sliding, sentiment may remain weak across the sector.

Also watch any update on data-centre demand, memory pricing, and whether the market rethinks the impact of AI regulation on future chip spending.
