Chip storage stocks jumped in overnight trading. Western Digital up 4%; SanDisk, Micron up 2%; Seagate up 1%.

Sandisk Corp. (SNDK) has advanced more than 1,030% in the past six months, as artificial intelligence has emerged as the top theme in the past years.

The pioneer in flash memory became a public company in 1995 and was then acquired by Western Digital (WDC) in 2016.

Just last year, the company was re-established as a stand-alone company, adding almost 1,200% to its stock since then.

Last August, its brand consolidated into a single brand strategy; in September, it began its manufacturing expansion; in November, the company reported impressive beats on its Q1 results, prompting analysts to be bullish on SNDK.

It was also reported that the company could double the price of its high-capacity 3D NAND memory devices for enterprise-grade solid-state drives in the first quarter of 2026 as it anticipates strong demand for server-class storage in the coming quarters.

More recently, Sandisk (SNDK) rallied after unveiling its Optimus SSD brand at CES 2026, as well as GX and GX Pro tiers for gamers, creators, and AI workloads.
