The memory stock rally continues as Micron (MU) has delivered Q1 2026 non-GAAP EPS of $4.78 beating expectations by 21% with revenue of $13.64B, up 57% year-over-year, while SanDisk (SNDK) posted Q3 FY2026 EPS of $23.41, beating estimates by 60%.
Structural memory chip shortages tied to AI infrastructure spending are driving institutional rotation into hardware suppliers, with NAND flash prices rising 60% in Q1 2026 and Q2 hikes projected at 70-75%, marking pricing power the memory market hasn’t seen in years.

Memory chip stocks are ripping higher again this morning, with Micron Technology (NASDAQ:MU) shares up 12% and SanDisk (NASDAQ:SNDK) shares climbing 10% in mid-morning trading on Tuesday. MU stock is changing hands near $644, while SNDK shares are pushing through $1,380.
The synchronized rally extends what's already been a parabolic year for memory names. Micron stock is up 125% year to date, while SanDisk shares have surged 478% in 2026 so far. Both stocks hit fresh 52-week highs last week alongside Intel (NASDAQ:INTC) stock, per MSN coverage published May 4.
The catalyst is straightforward. A structural memory shortage narrative now drives aggressive institutional rotation into hardware suppliers tied directly to AI infrastructure spending.
Micron's move builds on a stunning fiscal Q1 2026 report, where the company posted non-GAAP EPS of $4.78 against a $3.94 consensus and revenue of $13.64 billion, up 57% year over year. The Cloud Memory Business Unit alone delivered $5.28 billion in revenue at a 66% gross margin.
The company's Q2 FY2026 guidance pointed to revenue of $18.7 billion and non-GAAP EPS of $8.42, with order books reportedly stretching into 2027. Micron Technology CEO Sanjay Mehrotra stated that the outlook reflects "substantial records across revenue, gross margin, EPS and free cash flow" with Micron positioned as "an essential AI enabler."
The MU stock bull case rests on tight High Bandwidth Memory (HBM) supply, hyperscaler order visibility, and a P/E ratio of 26x that bulls argue still looks reasonable given earnings momentum. The bear case is harder to ignore: insiders have logged 11 recent transactions with net selling, and the average analyst target price of $551.4 sits below today's print.
SanDisk stock's rally has been even more dramatic. Last Thursday's fiscal Q3 2026 report featured EPS of $23.41 against a $14.66 estimate and revenue of $5.95 billion, up 251% year over year. The Datacenter segment exploded 645% year over year to $1.47 billion.
CEO David Goeckeler called the period "a fundamental inflection point for Sandisk, where our technology leadership is enabling a deliberate shift in our mix toward the highest-value end markets, led by Datacenter." SanDisk's Q4 FY2026 guidance calls for revenue between $7.75 billion and $8.25 billion with non-GAAP gross margin of 79% to 81%.
The balance sheet story matters, too. SanDisk retired $650 million in debt last quarter, leaving the company with zero long-term debt, and authorized a fresh share repurchase program. Our recent take on whether to buy, sell, or hold Micron and SanDisk at current levels framed both names as core AI infrastructure beneficiaries.
Yet, the parabolic chart raises legitimate concern. Mizuho recently called the "peak memory" fears overblown, but the SNDK price prediction model still implies some downside to $1,198. Reddit chatter shows retail traders already rotating SNDK gains into other names, a potential momentum-exhaustion signal.
The bigger question is whether the memory supercycle holds through 2027 as bulls insist, or whether technological efficiencies and capacity additions cool pricing power sooner. NAND flash prices reportedly rose 60% in Q1 2026, with current-quarter hikes projected at 70% to 75%. That's a level of pricing power the memory market hasn't seen in years.
Prudent investors may want to consider trimming positions into strength rather than chasing. Both stocks have moved well past most analyst targets, and synchronized rallies of this magnitude tend to pause before they extend. The Roundhill Memory ETF (NYSEARCA:DRAM) crossing $1 billion in AUM in under 10 days shows just how crowded this trade has become.
Watch for whether MU stock can hold the $640 area into the close and whether SNDK shares can defend $1,375. Any analyst commentary out of this week's tech conferences could shape the next leg of the move.
