Hello, this is Daily Stock.
Key Summary
On June 23, 2026 (local time), just one day before releasing its fiscal Q3 2026 earnings results, U.S. semiconductor memory giant Micron Technology (MU) plummeted 13.18%, tumbling to $1,051.77 per share.
This sharp decline was triggered by a combination of factors: a coordinated sell-off in Asian semiconductor stocks sparked by South Korean financial authorities' warnings over high-risk semiconductor leverage ETFs, alongside growing anxieties regarding a potential slowdown in SK Hynix's HBM4 ramp-up pace.
However, Wall Street's expectations for Micron's Q3 performance remain record-high, and any future rebound in Micron's stock price will heavily depend on the guidance presented during the earnings call and its supply dominance in the HBM market.

Market Overview
Micron had recently been on a sustained rally, hitting an all-time high of $1,211.38 per share on June 22, 2026, only to erase those gains in a single day of sharp selling.
Looking at the domestic financial markets as of 9:00 AM on June 24, 2026 (tentative), the KOSPI is at 8,268.55 points, while the KOSDAQ stands at 893.89 points.
The South Korean Won against the U.S. dollar is trading at a high of 1,534.00 KRW, and the Nasdaq Composite in New York closed the previous session down 2.22% at 25,587.04 points.
Looking at our proprietary Fear & Greed Index, the KOSPI Fear & Greed Index is currently in the "Fear (28.8)" stage, a sharp deterioration from the "Neutral (53.4)" stage recorded a week ago.
The Nasdaq Fear & Greed Index also registers in the "Fear (27.5)" stage, signaling entrenched anxiety following the previous week's "Fear (39.1)" reading.
The catalyst for this plunge was a warning from South Korean financial regulators regarding leveraged ETFs. This triggered a massive sell-off in Korea's two memory giants—Samsung Electronics (-12.31%) and SK Hynix (-12.47%)—which immediately spilled over to the U.S. markets.
This was compounded by reports that SK Hynix is fine-tuning its HBM4 ramp-up speed to prioritize the production of highly profitable conventional DRAM, fueling excessive anxiety over a slowdown in AI semiconductor demand.
Financial Analysis
The consensus is that Micron’s fiscal Q3 2026 results will mark the strongest performance in the company's history.
According to LSEG Consensus, Micron's revenue for the quarter is projected to surge by a massive 282.6% year-over-year to approximately $35.59 billion.
Below is a financial table comparing Micron Technology's outlook for this quarter with its previous quarter and the same period last year.
| Metrics | FY25 Q3 (Actual) | FY26 Q2 (Actual) | FY26 Q3 (Consensus Est.) | YoY Change (%) |
|---|---|---|---|---|
| Revenue | $9.301 B | $23.86 B | $35.59 B | +282.6% |
| EPS | $1.91 | $12.20 | $20.28 | +961.8% |
| Gross Margin | 39.1% | 74.9% | 81.6% | +42.5%p |
This unprecedented financial growth is fueled by strong pricing power in High Bandwidth Memory (HBM), which is indispensable for Nvidia’s next-generation AI chip designs.
In particular, within a market structure virtually split three ways for high-margin HBM3E and HBM4 products, Micron has already fully sold out its high-bandwidth memory production capacity through the end of 2026.
Valuation
Despite the recent drop in stock price, Micron’s trailing 12-month (TTM) P/E multiple stands at approximately 49.7x, significantly higher than its 5-year median of 20.7x.
Looking at this metric alone, arguments that Micron's valuation has entered historically overvalued territory carry considerable weight.
However, its forward P/E multiple—which factors in the explosive earnings forecast over the next 12 months—drops to approximately 9.2x to 9.6x.

This indicates that the memory market has fundamentally shifted from a traditional commodity-style cycle to a structural core pillar of high-value AI infrastructure.
Nevertheless, given the cyclical nature of the semiconductor industry, if capital expenditure overheating leads to oversupply, current valuations could turn out to be distorted at the peak of the cycle.
Analyst and Institutional Commentary
Global financial institutions view this 13% decline not as a breakdown of fundamental business operations, but as a temporary buying opportunity caused by macro factors and technical supply-demand distortions.
Notably, Vivek Arya, senior analyst at Bank of America (BofA), raised Micron's price target sharply from $950 to $1,500 on the day of the plunge.
BofA emphasized, "DRAM and HBM are not mere cyclical commodities; they are mission-critical assets whose demand expands exponentially with each Large Language Model (LLM) upgrade."
In addition, Susquehanna maintained a highly bullish price target of $1,750, and UBS kept its target at $1,625, both giving high marks to Micron's HBM4 leadership.
Wedbush also analyzed that corporate enterprise demand remains highly robust, making this correction a strong scenario for a buying opportunity.
Risk Factors
The most immediate risk is the fear of prolonged high interest rates driven by shifts in the Federal Reserve's monetary policy.
Some corners of Wall Street have begun pricing in the possibility of an additional 50bp rate hike by the end of the year under the new Fed Chair, Kevin Warsh.
This could increase the cost of capital (CAPEX) burden for Big Tech companies, which have been funding massive AI investments through debt and leverage.
Furthermore, the volatile supply-demand situation in South Korea—where retail investors make up over 90% of leveraged single-stock ETFs—could repeatedly trigger volatility originating from Asia.
Lastly, the risk of long-term oversupply cannot be ruled out. If capacity expansion coincides with a period of slowing demand, it could result in a steep degradation of margins.
Investment Outlook & Conclusion
In conclusion, the 13% plunge right before earnings appears to be an overreaction driven by macro anxieties and external technical flows rather than internal issues at Micron.
Therefore, the conditions investors need to monitor for a stock rebound are clear:
First, in the upcoming earnings release after the market close on June 24, Q3 results must not only meet consensus but its Q4 guidance must also comfortably beat market expectations.
Second, management must demonstrate during the conference call that the structure of its long-term HBM supply contracts extending past 2026 remains solid and its pricing power is being sustained.
If these conditions are met, the stock is highly likely to quickly recoup its losses and enter a full-fledged re-rating phase.
FAQ
Q1. What was the main reason behind Micron's 13% drop right before earnings?
A1. South Korean financial regulators issued warnings regarding high-risk leveraged ETFs tracking Samsung Electronics and SK Hynix. This triggered a sell-off in Asian memory stocks, which quickly spread to Micron in the U.S.
Q2. Why did SK Hynix's HBM4 timeline adjustments affect Micron's stock?
A2. Analysis showing that SK Hynix might adjust its HBM4 roadmap to focus on highly profitable conventional DRAM was misinterpreted by the market as a signal of slowing AI demand, sparking a wave of selling.
Q3. What are the specific consensus numbers expected for Micron's Q3 earnings?
A3. Consensus estimates project quarterly revenue of approximately $35.59 billion, up over 280% year-over-year, with EPS expected around $20.28, signaling a record earnings surprise.
Q4. What is the essential guidance condition required for a stock rebound?
A4. Beyond reporting strong historical results, Micron must upwardly revise its revenue and margin guidance for the next quarter and reaffirm the strength of its backlogged supply commitments through 2026.
Q5. What is the actual risk that changing interest rate outlooks pose to Micron's valuation?
A5. As the possibility of an additional 50bp Fed rate hike by the end of the year surfaces, multiples for high-valuation tech stocks are under pressure, which could increase the capital spending burden for Big Tech infrastructure investments.
