Memory stocks are extending their rebound Tuesday morning, with SanDisk (NASDAQ:SNDK | SNDK Price Prediction) up 8% to $1,504, Western Digital (NASDAQ:WDC) up 9% to $531, and Micron Technology (NASDAQ:MU) up 7% to $923. Today’s gains build on a July 20 session in which the same names rose 4% to 6%, turning a summer pullback into a two-day rebound for the group.
The specific catalyst on the tape today belongs to Micron. Bank of America analyst Vivek Arya raised his Micron price target to $1,550 from $1,500 and reiterated Buy. SanDisk and Western Digital are riding the broader memory tape and a constructive UBS note.
Bank of America Fuels the Micron Leg
Arya characterized Micron’s latest quarter as “another memorable beat,” pointing to the company’s eighth straight quarterly EPS beat, which topped consensus by 24%. He framed the recent chip pullback as a “summer reset.”
The Bank of America note pegs the high-bandwidth memory (HBM) opportunity at $246 billion by 2030 and global semiconductor sales at $2.7 trillion by 2030. Micron has locked in 16 multi-year Strategic Customer Agreements, including a supply-and-investment partnership with private AI lab Anthropic.
Micron’s Q4 FY2026 guidance calls for revenue of $50 billion plus or minus $1 billion, non-GAAP EPS of $31 plus or minus $1, and gross margin of 86%. The stock’s forward P/E ratio of 5x looks unusually low for a name compounding at this pace, and analyst targets reflect that view: TD Cowen sits at $1,500, with the Street’s consensus at $1,491.95.
UBS piled on Monday, writing that Micron could repurchase more than 40% of its shares by the end of 2028 and generate over $400 billion in free cash flow through 2028. The bank flagged Micron, SanDisk, Western Digital, Seagate Technology (NASDAQ:STX), Broadcom, and Advanced Micro Devices (NASDAQ:AMD) as attractive at current levels.
SanDisk and Western Digital Ride the Memory Wave
SanDisk stock has run 533% year to date (YTD), and Western Digital shares are up 207% YTD. Both moves sit on top of sharp monthly pullbacks, so today’s gains function as much as a snap-back trade as a fresh leg higher.
Neither name printed a company-specific catalyst overnight. SanDisk stock and Western Digital shares are moving on the same AI memory thesis that lifted Micron, along with UBS’s constructive read across the storage complex. The setup mirrors the earnings cadence, where SanDisk posted datacenter segment revenue of $1.47 billion, up 645% year over year (YoY) in its most recent quarter, and Western Digital crossed 50% non-GAAP gross margin for the first time.
For diversified exposure, the Roundhill Memory ETF (NYSEARCA:DRAM) is extending its rebound alongside the group. The fund is heavily concentrated, with Samsung Electronics at 25%, SK Hynix (NASDAQ:SKHY) at 24%, and Micron Technology at 24% of net assets. It’s a narrow, single-theme thematic vehicle (but not leveraged), and the concentration risk in a handful of mega-cap memory makers is real.
What to Watch Into a Heavy Earnings Week
The next catalysts arrive fast. Intel (NASDAQ:INTC) reports Thursday, Alphabet (NASDAQ:GOOGL) reports this week, and SK Hynix reports July 29. Any commentary on hyperscaler capex, HBM pricing, or NAND supply from those calls can either extend the memory rally or trigger another rotation out of the group.
Investors may want to size their positions modestly here. These are high-beta names with powerful YTD runs, and the memory tape can turn on a single guidance data point. The bull case rests on structural AI demand, HBM pricing power, and multi-year customer agreements; the bear case is that memory pricing peaks earlier than Street models assume, and July’s drawdown showed how quickly that fear can compress multiples.
Market watchers can check for whether today’s gains hold into the close and whether Intel’s report Thursday validates the hyperscaler capex thesis. That’s the next real information point for the memory/storage trade.
