Michael Burry Turns Bearish on Micron Technology Stock

Investor Michael Burry (Trades, Portfolio) disclosed a short position in Micron Technology NASDAQ:MU while increasing several existing long holdings.

Burry said his Micron position reflects concerns that the recent rise in Micron shares may have been fueled by investor enthusiasm rather than underlying fundamentals. He described Micron as a highly cyclical business and pointed to the stock's history of large declines during prior market cycles.

Micron shares have climbed more than 240% since the beginning of 2026, driven partly by demand tied to artificial intelligence and memory-related spending trends. However, Micron has also retreated around 10% over the past month as investors reassessed semiconductor valuations.

Burry said he may expand bearish positions if volatility moderates.

The investor previously disclosed short positions involving Nvidia NASDAQ:NVDA, Applied Materials NASDAQ:AMAT, and the iShares Semiconductor ETF NASDAQ:SOXX, reflecting broader caution around semiconductor shares tied to the AI trade.
