$Micron Technology(MU)$ Bullish
SK Hynix (SKHY) and Micron (MU) Comparison
SK Hynix began volume shipments in the second quarter of HBM4 utilizing 1b DRAM and Advanced MR-MUF packaging. Samples of its 48GB, 12-layer HBM4E have been provided to major customers, featuring a single-pin speed of up to 16 Gbps and an energy efficiency improvement of over 20% compared with HBM4, and it is currently in the customer validation stage.
Micron's 36GB, 12-layer HBM4 utilizing 1β DRAM has begun volume shipments for Nvidia's Vera Rubin platform, with bandwidth exceeding 2.8 TB/s. HBM4E utilizing 1γ DRAM is expected to enter mass production in 2027, while SOCAMM2 and PCIe 6.0 data center SSDs have also entered mass production.
SK Hynix reported second-quarter 2026 revenue of 79.32 trillion Korean won with a K-IFRS operating margin of 76%; Micron reported third-quarter fiscal 2026 revenue of $41.456 billion, a US GAAP operating margin of 80.4%, and operating cash flow of $25.388 billion.
Both companies have benefited from rising memory prices and growing shipments of high-value-added products, with current profit margins sitting at cyclical highs.
SKHY vs. MU: Which Is Better for Long-Term Holding?
As of September 23, 2026, SKHY and MU closed at $189.28 and $1,071.88, respectively.
SKHY's 20-day simple moving average is approximately $177.18. The $185–$186 range serves as the immediate primary support level; if breached, the next support to monitor is around $177–$178. To the upside, $199.87–$200 forms a major resistance zone, and a breakout could bring the previous high region into focus.
MU's 20-day simple moving average is approximately $979.69. The $1,040–$1,065 range is the near-term support zone, with $1,042.40 marking a previous breakout level and around $1,064 corresponding to the intraday low on September 23.
To the upside, $1,097–$1,105 represents a near-term resistance zone; if it establishes a firm footing on heavy volume, the next upside target could be the all-time high of $1,255 set in June.
Over the long term, SKHY is better suited for investors who value HBM mass-production experience and can tolerate depositary receipt price spreads and South Korean won exchange rate fluctuations. MU features a Nasdaq common stock structure, where USD trading and SEC financial disclosures make it easier for US investors to track.
SK Hynix boasts richer experience in HBM mass production, but its HBM4E remains in the sample delivery and customer validation stage; Micron Technology, on the other hand, has begun volume shipments of HBM4 for Nvidia's Vera Rubin platform. In comparison, SKHY may offer higher stock price elasticity, while MU provides a more direct security structure and trading basis.
Key variables over the next three years include HBM4 volume expansion, HBM4E mass production progress, advanced packaging yield, customer concentration, and return on capital expenditures. Following substantial rallies in both stocks, subsequent performance will mainly depend on order execution and whether earnings growth can be sustained.

Investors are eagerly awaiting Micron Technology’s fiscal fourth-quarter earnings on September 30 to see whether the memory chip company continues to enjoy solid demand and pricing tailwinds.
Ahead of Q4 FY26 earnings, BMO Capital analyst reiterated a Buy rating on MU stock with a price target of $1,300. The analyst is bullish on Micron, as he believes that “memory remains in a supercycle as demand trends continue to exceed supply through CY27.”
Kumar ranks No. 9 among more than 12,500 analysts tracked on TipRanks. He has a 74% success rate, with an average return per rating of 46.9% over a one-year period.
Kumar raised his Q4 FY26 revenue estimate by $2 billion. He also increased his full-year FY27 revenue and EPS estimates to $268 billion and $168.62, respectively, from $249 billion and $151.91. Kumar doesn’t expect any new significant memory supply to arrive until the second half of 2027.
Meanwhile, Kumar expects HBM and DDR5 to drive Q4 FY26 results, with BMO’s checks indicating server DDR5 pricing offering the greater upside surprise. The analyst noted that both HBM3e and HBM4 likely saw a sequential rise in pricing, while client and consumer memory saw weaker demand.
For Q1 FY27, Kumar expects . He sees HBM3e and HBM4 prices rising modestly under annual pricing contracts. While server DDR5 pricing continues to offer the greater potential for upside surprises, Kumar expects demand to shift towards HBM4. Kumar highlighted that, as per his checks, HBM4 carries about a 20% to 25% price premium compared to HBM3e. As the product mix shifts toward HBM4, Kumar expects the average selling price (ASP) to move higher.
Meanwhile, Wall Street expects Micron to report , up from $3.03 in the prior-year quarter. Revenue is projected to surge about 351% to $51.07 billion.
Is Micron Stock a Good Buy?
With 20 Buys and one Hold, Wall Street has a Strong Buy consensus rating on Micron Technology stock. The average of $1,526.75 indicates 41.2% upside potential.
Micron Technology recently joined the elite club of trillion-dollar companies after its stock skyrocketed more than 900% in one year.
The company is benefiting from a tremendous memory pricing cycle, thanks to demand for artificial intelligence infrastructure.
Tight memory supply is driving ridiculous pricing growth, boosting revenue and profitability, and we expect supply constraints to keep prices rising into 2027. But the key question is how long this cycle lasts and how high it goes.
We expect a peak between 2027 and 2028 and a precipitous downcycle thereafter, in 2029.
