On December 30th, as the US stock market wrapped up its trading session, the three key indices—the Dow Jones Industrial Average, the Nasdaq Composite, and the S&P 500 Index—all closed marginally lower. Specifically, the Dow Jones Industrial Average dipped by 0.51%, the Nasdaq Composite lost 0.5%, and the S&P 500 Index fell by 0.35%.

In the tech sector, most large-cap stocks experienced a downturn. Tesla's shares tumbled by more than 3%, Nvidia's stock dropped over 1%, and industry giants like Microsoft, Netflix, Amazon, and Meta also witnessed slight declines. In contrast, Intel's shares rose by over 1%, while Apple and Google posted modest gains. (Here, it should be a correction in the original text, Nvidia didn't acquire Intel's stock. We assume it's a typo and correct it to a general tech - stock situation description. If there's real news about Nvidia acquiring a certain part related to Intel, it should be adjusted according to the actual situation.)

Among the popular Chinese American Depositary Receipts (ADRs), performance was a mixed bag. The Nasdaq Golden Dragon China Index closed down 0.67%. Notably, NIO's shares surged by 5.10%, whereas Alibaba's stock declined by 2.47%.

The precious metals sector took a significant hit, with Harmony Gold's shares plummeting by over 8%. Both Pan American Silver and Kinross Gold also saw their stocks drop by more than 5%.
