On September 14, Marvell Technology fell 8.31% in regular trading, trading at 215.99 USD/share, with turnover of approximately $804 million.

On the news front, the U.S. Federal Communications Commission officially published its final rule titled Protecting Against National Security Threats to the Communications Supply Chain Through the Equipment Authorization Program, set to take effect in 30 days. Earlier rumors of FCC restrictions on Chinese optical communications firms had previously driven a sharp rally in U.S. optical networking stocks. With the rule now formally enacted, a classic buy-the-rumor-sell-the-news dynamic unfolded, sending the optical communications sector broadly lower from pre-market trading onward. Peers including Corning, Coherent, and Ciena all declined over 5%.

The broader semiconductor sector also saw widespread selling, with NVIDIA down 3.98%, Micron Technology down 7.13%, AMD down 5.93%, Intel down 7.02%, and Broadcom down 3.9%. With Marvell Technology having accumulated gains of nearly 178% year-to-date, elevated valuations amplified pullback pressure as sector headwinds intensified.
