#美光市值突破1万亿美元 Micron Technology (MU) saw its stock price surge by 19.29% in a single day on May 26, 2026, with its market capitalization surpassing $1 trillion, marking an important milestone in the semiconductor industry:

1 Stock Price Performance
The highest intraday price reached $916.8, closing at $895.88, the largest single-day increase since 2011. As of May 27, the after-hours stock price further rose to $908.93, with bullish market sentiment continuing to be high.
2 Market Cap Breakthrough
Micron became the 13th publicly traded company worldwide to break the $1 trillion market cap, and the sixth giant in the global semiconductor industry to join the "trillion-dollar club," following Nvidia, TSMC, Broadcom, Samsung, and ASML.
3 Rally Logic
AI Demand Explosion: The demand for high-bandwidth memory (HBM), DDR5, and other storage chips for AI servers has surged, with supply and demand imbalance driving prices higher.
Cycle Shift to Growth: Long-term supply agreements (LTA) lock in orders, reducing cyclical volatility and allowing for valuation re-rating.
Technological Leadership: Micron leads the industry in advanced process technologies such as HBM3E and HBM4, with capacity fully sold out and high order visibility.
4 Institutional Views
UBS has significantly raised its target price for Micron from $535 to $1,625, believing its valuation should shift from cyclical stocks to growth stocks, with enormous future earnings growth potential. Other investment banks like Deutsche Bank and Bank of America Securities also issued buy ratings, with target prices in the $950–$1,000 range.

In terms of strategy, chasing the high now is not advisable. It’s better to wait for a price correction to a certain support level (such as a previous breakout resistance or near key moving averages) before considering phased buying to reduce the risk of chasing highs.
Alternatively, investors can indirectly participate by investing in semiconductor industry ETFs (such as SMH, SOXX, etc.), diversifying individual stock risk while sharing the overall industry growth dividends.$MU
