U.S. stocks closed modestly higher on Thursday, buoyed by a 3.2% rise in Nvidia shares following the company's stronger-than-expected quarterly sales report. Investors also absorbed a late-afternoon court ruling that temporarily reinstated the most comprehensive tariffs imposed by former President Donald Trump. The U.S. appeals court approved Trump's request to restore these tariffs, prompting mixed reactions, including a welcoming response from China regarding the court's earlier invalidation of the tariffs. Additional market developments included the U.S. Securities and Exchange Commission dropping lawsuits against Binance and its CEO Changpeng Zhao, new export restrictions imposed on Yihua Computer concerning China, and the U.S. government's decision to begin revoking visas for Chinese students.
