Memory names in the US are running again with SNDK US STX US MU US and WDC US all up sharply today. The later has posted a new all time high as well.

I follow the sector closely and have done for 25 years.

SNDK US SanDisk have been one of my top picks this year- since they were spun out of Western Digital WDC US, which retained a 1 9.99% stake in the flash memory maker.

SNDK shares have added +480.0% since the spring .

Why?

Well there is a structural squeeze in the memory chip market. SK Hynix in Korea has sold out its entire 2026 output already. Local rival Samsung has jacked up its prices significantly.

High-end dynamic memory chips are essential in NVIDIA’s AI chips and high-end processors, the net result is booming stock prices for other names in the sector.
