Sandisk Jumps 6% As Rosenblatt Starts Coverage At Buy With $2,400 Target; Micron Rises 3%, Seagate Ticks Up

Rosenblatt Securities has initiated coverage of SanDisk (NASDAQ:SNDK) at Buy, and the note is powering a clean divergence between memory names and the broader U.S. market Tuesday morning. SanDisk stock is at $1,875, up 6% in Tuesday morning trading, extending a run that has carried the shares up 677% year to date.

Memory names are riding the read-through. The Roundhill Memory ETF (CBOE:DRAM) is at $62.66, up 2% in Tuesday morning trading. Meanwhile, the SPDR S&P 500 ETF Trust (NYSEARCA:SPY) sits at $773.46 and is essentially unchanged, marking the memory bid as sector-specific rather than a broader risk-on session.

Checking in on the peers, Micron Technology (NASDAQ:MU) stock is at $1,075.68, up 3% in Tuesday morning trading, tracking SanDisk higher on the shared artificial intelligence (AI) memory narrative. Seagate Technology Holdings (NASDAQ:STX) stock is at $885.95, up 1%, a more measured bid that reads as SanDisk-specific rather than a new call on storage pricing. Western Digital (NASDAQ:WDC) is also caught in the sympathy move as the pure-play HDD company left after the SanDisk separation.

Rosenblatt Frames NAND as AI Infrastructure

Kevin Cassidy at Rosenblatt argued that new AI compute platforms are repositioning NAND flash memory “from a commodity storage medium to a more system-critical component of AI infrastructure,” with density, performance, endurance and supply certainty starting to matter more to buyers than the lowest price per bit. That framing is the crux of the SanDisk call, and it’s why Cassidy set a price target of $2,400 on the stock.

Cassidy pointed to SanDisk’s BiCS8 and BiCS10 platforms, developed over decades with manufacturing partner Kioxia, saying they achieve higher storage density with fewer layers than some rivals and can sustain a cost and performance edge in enterprise storage built for AI workloads. Cassidy also flagged new business model agreements SanDisk has struck with eight of its largest NAND customers, estimating they could cover 65% of fiscal 2028 production and lend the kind of demand visibility the NAND market has historically lacked.

The customer agreements are the piece of the SanDisk story worth tracking more closely than the target itself, because contracted volumes into fiscal 2028 are what would actually damp the boom-bust cycle NAND has always run through, according to Rosenblatt. He did not soft-pedal the risks either, naming execution risk and the possibility that NAND reverts to cyclical, commodity-like pricing as the plain counterweights to his bull case.

Peer Bids and Sector Read-Through

Micron shows the cleanest peer read-through. The move on Micron stock reflects the same AI-memory frame that anchors Cassidy’s SanDisk thesis, though the smaller gain suggests the initiation is being treated as idiosyncratic rather than a re-rating of DRAM or high-bandwidth memory pricing across the group.

Seagate’s advance is smaller still. Its exposure to mass-capacity HDD demand from hyperscalers overlaps with the AI storage narrative, but the Rosenblatt note itself targets NAND, so Seagate’s price action reflects an adjacent tailwind rather than a direct read.

Western Digital sits alongside Seagate as the other HDD name catching the day’s spillover. The Western Digital bid is modest, and the storage complex looks like it’s enjoying a halo effect from the memory move, without the same conviction the Rosenblatt note itself places on SanDisk.

The Roundhill Memory ETF’s move captures the sector tilt without overstating it. With the SPDR S&P 500 ETF Trust flat on the session, the memory bid stands out cleanly against a benchmark that isn’t doing much, and the wider AI buildout reaches past chips into the power, cooling, and networking suppliers we covered in a free report here.

What to Watch Next

SanDisk stock’s bull case rests on Cassidy’s argument that AI workloads change what NAND is worth. However, SanDisk’s year-to-date advance means much of that thesis is already reflected in the share price, and Cassidy’s own bear flag on commodity cycles is a live risk that shouldn’t be waved away.

Investors can watch for whether SanDisk’s customer agreements convert into the contracted, multi-year demand that would actually damp the NAND cycle Rosenblatt itself flagged. Traders may want to keep an eye on whether Micron and Seagate hold their smaller gains into the close, since a fade in the peer bid would confirm the market is reading the initiation narrowly.

Position sizing across SanDisk, Micron and Seagate should reflect the year-to-date runs already booked and the cyclical risk baked into the NAND story. A cautious approach keeps their exposure aligned with the range of outcomes Cassidy himself named, not just the target.
