TradingKey - Latest market data shows that last Friday (June 26), Micron ( MU) pulled back on the first day of trading after reporting exceptionally strong earnings. The stock briefly surged to $1,198.71 intraday before retreating to around $1,121.36, closing the day down 6.69%. The price action indicates that following recent sharp gains, increased profit-taking has emerged, signaling strong profit-taking pressure on the stock at these high levels.
Fundamentally, Micron's strongest support remains the surging demand from AI servers for high-bandwidth memory, DRAM, and enterprise storage.
Over the past few years, when the market discussed AI hardware, the focus was primarily on Nvidia ( NVDA) GPUs, advanced packaging, and foundries. However, as the costs of large model training and inference rise, the importance of memory bandwidth, capacity, and power efficiency has been significantly elevated, placing Micron at the very center of this supply chain revaluation.
The latest earnings report further reinforces this logic. Micron's third-quarter fiscal 2026 revenue reached $41.46 billion, representing a significant increase from both the prior quarter and the same period last year, while non-GAAP EPS reached $25.11 and operating cash flow also expanded significantly. More importantly, the company's fourth-quarter guidance continues to beat market expectations, with projected revenue of approximately $50 billion and non-GAAP EPS of around $31. This indicates that current demand is not just a single-quarter spike, but is continuing to carry over into subsequent quarters. For growth stocks, the market's biggest fear is peaking revenue, but the signal Micron is currently sending points toward continuous upward revisions in earnings.
Meanwhile, as one of the big three in the global HBM market, Micron stands to benefit as HBM chips have become critical components for AI servers and data centers amid rapid AI development. While demand continues to grow, production capacity remains relatively limited, which will support a continuous rise in HBM chip prices.
However, strong fundamentals do not mean the stock is risk-free. Over the past year, Micron's stock has surged by a cumulative 1,103%, and its market capitalization has reached the trillion-dollar level, indicating that the market has already priced in a massive amount of optimism. Although the company's earnings growth is rapid, the current trading logic is not a bottom-up reversal, but rather earnings realization in the mid-to-late stages of an upcycle. For the market, whether Micron's valuation can continue to expand depends crucially on whether HBM and high-end DRAM prices can maintain their strength, and whether the company can expand capacity while avoiding future oversupply.

Looking at Micron's daily chart, the overall candlestick pattern shows a clear structure of higher highs and higher lows, indicating that Micron's overall trend maintains a strong bullish structure. Additionally, although the stock price has experienced corrections, the overall movement remains above the 20-day moving average, further reinforcing the overall uptrend.
Currently, Micron underwent a correction last Friday. Today, it should be noted that if the stock price falls below the 5-day moving average and breaks last Friday's low of $1,121.36, the stock price will continue to move downward to test the 10-day moving average support and the area near the $1,089 support level. If the $1,089 support level is breached, the stock price will decline further to test the $1,050 support level and the 20-day moving average support.
On the upside, as the stock price broke through the Fibonacci 1.0 extension level of $1,158, it has further opened up upside potential toward $1,472. Currently, the focus is on whether the stock price will fall below the $1,121.36 support level. If today's closing price is above this level, the upward trend will continue. If it falls below, attention should be paid to the support levels at $1,089 and $1,050 below; if a signal of bottoming out and stabilizing appears, one could attempt to go long.
