Dell fell 6% and Western Digital surged 5%, splitting the AI trade between memory sellers gaining pricing power and assemblers absorbing higher costs.
Micron's blowout quarterly results sparked the memory rally, lifting SanDisk alongside Western Digital as AI data center demand validates elevated storage valuations.
Dell's gross margin compressed from 21% to 18% last quarter, and climbing memory costs threaten to deepen that squeeze heading into August earnings.

Shares of Dell Technologies (NYSE:DELL) are down 6% in midday trading Thursday, last changing hands near $407 after closing at $434.06 on Wednesday. The slide stands out because it's happening on a day when memory and storage names are ripping higher.
At the same time, Western Digital (NASDAQ:WDC) stock is up 5%, trading near $678. The split between a server and PC builder falling while a storage maker rallies tells the story of today's market action in AI hardware stocks.
Both names have been monster performers in 2026. Dell stock is up 224% year to date through Wednesday's close, while Western Digital stock has climbed 296% year to date. Today's divergence isn't subtle.
Two Sides of the Memory Boom
The catalyst behind Western Digital's move is straightforward. Memory and storage stocks rallied after Micron Technology's (NASDAQ:MU) blowout quarterly results "justify elevated valuations" and reinforced the view that AI capital spending keeps accelerating. Memory has been a bottleneck in the AI buildout, and that scarcity is now showing up as pricing power for the suppliers.
Western Digital is a pure-play HDD beneficiary of that dynamic. The company's most recent quarter showed non-GAAP gross margin of 51% and revenue of $3.34 billion, up 46% year over year. CEO Irving Tan summed up the demand backdrop, stating, "Virtually every AI workload, from training, inference, agentic AI to physical AI, creates data that is stored persistently and cost-efficiently on HDDs."

Dell's drop today doesn't have a single confirmed catalyst, but it likely reflects the flip side of that same memory squeeze. Dell builds servers and PCs that buy memory, so the rising prices lifting Western Digital and peers translate into input-cost pressure for Dell's box-maker business. It's the same dynamic behind hardware-cost worries hitting other consumer device names this week.
Margin Pressure Was Already Visible

Dell's most recent earnings made the margin issue concrete. In Q1 FY2027, the company posted revenue of $43.84 billion, up 88% year over year, alongside AI-optimized server revenue of $16.13 billion, up 757% year over year. The top-line growth here is undeniable.
Yet, the same report showed gross margin compressed to 18% from 21% year over year, with management attributing the pressure to a mix shift toward lower-margin AI servers. With memory costs climbing on top of that mix shift, the bear read on Dell today is that the margin math gets harder before it gets easier.
There's also a simpler explanation worth flagging. After a 224% run this year, some profit-taking in Dell stock is hardly surprising. One red day after that kind of rally isn't a thesis change.
Peers Follow the Split
The divergence is showing up across the complex. SanDisk (NASDAQ:SNDK) and Micron are riding the memory bid alongside Western Digital, while assemblers and hardware makers that purchase those components are mixed at best. Capital appears to be rotating, at least for the session, toward the picks-and-shovels suppliers feeding the AI buildout rather than the box makers stitching the systems together.
Western Digital isn't a cheap stock here. Sentiment in the WallStreetBets community spiked to a very bullish reading of 82 last week before cooling. That mix of retail enthusiasm and the scale of this year's run means expectations are elevated.
What to Watch
Western Digital reports its Q4 FY2026 results in late July, with the company guiding to revenue of $3.65 billion plus or minus $100 million and non-GAAP EPS of $3.25 plus or minus $0.15. Dell follows with Q2 FY2027 numbers in late August, with management guiding to revenue of $44 billion to $45 billion.
Investors can watch whether today's split widens into a broader rotation between memory suppliers and hardware assemblers, or fades as the market digests Micron's results. The next earnings cycle should clarify how much of the memory boom flows to margins, and how much gets absorbed by buyers like Dell.
