On September 14, Advanced Micro Devices fell 5.53% in regular trading, trading at approximately $488.72/share, with turnover of $19.5 billion. The decline was driven by the dual pressure of a CEO share disposal plan and broad semiconductor sector weakness.

On the news front, AMD CEO Lisa Su, acting as trustee, filed to sell 25,000 shares via the Lisa Su and Daniel Lin Family Trust, valued at approximately $13.03 million. Simultaneously, Su personally plans to sell 70,000 shares worth roughly $36.47 million, bringing the combined reduction to nearly $50 million. SEC Form 144 filings indicate Su has already conducted two prior sales totaling 45,000 shares in the preceding three months.

Adding to the pressure, Morgan Stanley downgraded its target price on ASML, triggering a sector-wide selloff. Within the Semiconductors sector, Marvell Technology fell 7.63%, Intel dropped 6.25%, Micron Technology declined 6.21%, Broadcom lost 3.75%, and NVIDIA slid 3.66%, underscoring the systemic nature of the downturn.
