The U.S. stock storage chip sector is in the main upward wave of an epic super cycle. Since May 2026, the sector has defied the trend with a breakout, with leading companies collectively hitting new all-time highs. This is not short-term speculative trading, but a resonance of three solid logical drivers: the AI computing power revolution igniting demand, rigid supply shortages locking in capacity, and continuous price surges driving performance. The industry has completely broken free from traditional cyclical constraints, with growth potential fully unlocked.

Currently, the U.S. stock market is volatile and somewhat weak, but the storage chip sector has emerged with independent strength, becoming the strongest main theme in the market. On May 4th (Monday), Micron Technology (MU) surged over 8%, with its stock price breaking through $2,000 to hit a new all-time high; SanDisk (SNDK) soared 7%, Western Digital (WDC) rose over 4%, Seagate Technology (STX) increased nearly 2%, with all four major leaders closing at historic highs. The gains over the past year are even more insane: SanDisk has increased over 2,600%, Western Digital over 880%, Seagate Technology over 700%, and Micron over 550%. No stocks in the sector declined, and the trend of capital consolidation is clear.
Performance has also exploded simultaneously: SanDisk’s latest fiscal quarter revenue reached $5.95 billion, a year-over-year increase of 251%, with net profit of $3.68B, up 280% quarter-over-quarter; Seagate and Western Digital’s revenue growth rates both exceeded 40% YoY, with performance surpassing expectations across the board, supporting continued stock price strength. In the short term, leading stocks could rise another 30%-50%, with Micron aiming for $2,500 and SanDisk reaching $1,800.
Risk warning: Attention should be paid to risks such as a global economic recession leading to lower-than-expected AI capital expenditure, and the early release of new capacity. However, under the current supply-demand pattern, the impact of such risks is limited.
