On December 16th, the three major U.S. stock indices ended the trading session with a mixed performance, all closing in negative territory. The Dow Jones Industrial Average dipped 0.09%, the Nasdaq Composite Index shed 0.59%, and the S&P 500 Index edged down 0.16%. While most large-cap technology stocks retreated, Tesla stood out as a notable exception, surging more than 3% to reach a fresh all-time high. This surge boosted Tesla's market capitalization by a staggering $53.7 billion (equivalent to approximately RMB 378.6 billion) overnight. As a result, Elon Musk's net worth soared to $677 billion, marking him as the first individual in history to surpass the $600 billion threshold in terms of net worth.

The semiconductor sector also faced headwinds, with most chip stocks experiencing declines. Broadcom saw its shares tumble more than 5%, while ARM's stock price fell over 4%. Additionally, popular Chinese American Depositary Receipts (ADRs) generally underperformed, with the Nasdaq Golden Dragon China Index sliding 2.17%. Among the notable decliners, Baidu's shares dropped nearly 5%, while Zhihu, Alibaba, and XPeng all saw their stock prices decline by more than 3%.
