SanDisk Slips 4.4% as Toshiba Capacity Talk and Micron's Muted Reception Rattle Memory Stocks

SanDisk closed at EUR 1,530.00, down 4.4%, as chip selling hit memory names; Citi reiterated Buy with a $2,100 target on tight NAND supply.

SanDisk shares closed Friday at EUR 1,530.00, down 4.4% on the day, as a broad wave of selling swept through semiconductor and memory names. Two separate currents fed the pullback: reports that Toshiba plans to expand its hard-drive manufacturing capacity, and a lukewarm market reception to Micron's latest quarterly report — which, despite solid figures and an upbeat outlook, failed to ignite sustained buying enthusiasm.

The Toshiba headlines stirred fresh worries about global storage supply, though the resulting oversupply fears landed hardest on conventional hard-drive makers such as Seagate and Western Digital. SanDisk got caught in the downdraft anyway, even though no direct link has been established. Meanwhile, Micron's tepid share reaction sowed doubts among investors over whether strong corporate results alone can keep the memory sector's recent recovery on track. After the sharp gains of preceding weeks, market participants used the hesitant mood to lock in profits on SanDisk. The stock now sits 26% below its 52-week high of EUR 2,060.00.

Citi Sticks With Buy Rating, Sees NAND Tightness Through 2028

Against that cautious tape, Wall Street's analyst community is striking a decidedly more constructive tone. On Thursday, Citi reaffirmed its "Buy" rating on SanDisk with a price target of $2,100, pointing to persistently tight supply in NAND flash memory. The bank's reassessment drew on Micron's recently released quarterly results, which showed substantial gains in both NAND revenue and realized selling prices. In Citi's view, that price and revenue trajectory underpins the fundamental case for SanDisk, even if short-term sector rotation is temporarily weighing on sentiment.

The analysts expect supply-side bottlenecks in the memory industry to persist through 2027 and 2028 — a projection that stands in direct contrast to the oversupply anxieties rippling through the broader storage market.

Insider Sale Adds to the Week's News Flow

Away from the trading action, there was movement at the leadership level. Chief Legal Officer and Secretary Bernard Shek sold a total of 600 company shares on Thursday under a trading plan adopted on March 4, 2026, in accordance with Rule 10b5-1. Following the transaction, Shek retains direct ownership of 25,588 shares. The sale follows earlier insider disposals roughly three weeks ago that had already drawn attention.

Quarterly Report on the Horizon

Investors will get their clearest read on operating momentum at the end of the month. SanDisk has scheduled the release of its financial report for the first quarter of fiscal year 2027 on October 29, 2026, with a conference call set for 1:30 p.m. Pacific Time the same day. Realized selling prices and NAND profitability are likely to dominate the discussion. Until then, the memory sector remains vulnerable to short-term swings in sentiment, even as the structural supply backdrop offers some support.

For now, the broader trend picture is intact: SanDisk continues to trade above its 50-day moving average of EUR 1,347.20.
