On September 24, Advanced Micro Devices fell 3.03% in pre-market trading, trading at $596.0/share, with turnover of $245 million. The stock had surged nearly 10% on September 21 to breach $1 trillion in market capitalization for the first time, but promptly slipped back below that threshold on September 23, intensifying short-term bull-bear contention around the milestone level.

On the news front, AMD's options market has been flooded with concentrated bearish signals over the past two sessions. A $7.5 million bear call spread and a $4.92 million long-dated put purchase emerged on September 22, followed on September 23 by a $1.96 million far-dated bear call spread targeting capped upside above $1,120, with overall large-order sentiment decisively skewed toward the short side. Meanwhile, renowned hedge fund manager Michael Burry publicly disclosed expanded short positions across the semiconductor sector, including memory chipmaker Micron, Nebius, iShares Semiconductor ETF, and Palantir, warning that supply-side normalization could trigger a cyclical downturn.

The broader semiconductor sector is under widespread pressure, with Intel down 3.10%, Micron down 2.23%, Broadcom down 1.61%, Taiwan Semiconductor Manufacturing down 1.38%, and NVIDIA down 1.07%. Macro headwinds including rising U.S. Treasury yields and a 54.2% implied probability of a Fed rate hike at the October meeting are adding to the risk-off tone.
