The company announced its earnings report after the market closed on Wednesday, with an adjusted earnings per share of $1.62 for the fourth quarter, compared to market expectations of $1.53. NVIDIA CEO Jensen Huang stated that customers are competing to invest in AI computing power. The second-ranked stock, Tesla, rose by 1.96%, with a trading volume of $X billion. According to media reports on February 25, a U.S. judge decided to proceed with a hiring discrimination lawsuit against Tesla, but also stated that the evidence from the plaintiffs is weak, and he is not optimistic about their chances of winning. It is reported that the lawsuit accuses Tesla of discriminating against U.S. citizens during the hiring process, prioritizing the employment of foreign workers with visas, thereby lowering labor costs. U.S. District Court Judge Vince Chhabria, based in San Francisco, noted in a brief ruling issued on Monday evening that Scott Taub, the plaintiff who filed the proposed class action last September, provided "just enough" factual statements regarding Tesla's hiring practices to allow the case to proceed to the next stage of litigation. The third-ranked stock, Microsoft, rose by 2.98%, with a trading volume of $17.19 billion. Reports indicate that Japan's antitrust agency, the Japan Fair Trade Commission, conducted an on-site investigation of Microsoft's Japan subsidiary on the same day for suspected violations of antitrust laws. It is reported that the Japan Fair Trade Commission believes Microsoft may be engaging in unfair competition in the cloud services market by leveraging its dominant position in office software and operating systems. Specifically, Japanese companies using Microsoft-related software on competitors' cloud platforms, such as Amazon, must pay higher fees than if they used Microsoft's own cloud platform, Azure. Regulators believe that this differential pricing practice may induce customers to switch to Microsoft's own platform, adversely affecting market competition. The sixth-ranked stock, AMD, fell by 1.39%, with a trading volume of $9.135 billion. The company signed a multi-year agreement with Meta Platforms yesterday to supply up to 6GW of GPUs. The agreement also includes a performance-based warrant allowing Meta to purchase up to 160 million shares of AMD stock. The tenth-ranked stock, Meta Platforms, rose by 2.25%, with a trading volume of $7.283 billion. Meta and AMD jointly announced a five-year strategic partnership on their official websites, where Meta will deploy AMD GPUs with a capacity of 6GW (with a transaction amount of several billion dollars per gigawatt). In exchange, AMD will provide performance-based warrants for up to 160 million shares (approximately 10% equity). Analysts believe that this strategic partnership indicates Meta's strong desire for continued expansion in the AI field and represents an important step for AMD to compete directly with industry leader NVIDIA. The fourteenth-ranked stock, Netflix, rose by 5.97%, with a trading volume of $5.545 billion. Paramount has raised its cash offer to acquire Warner Bros. Discovery to $31 per share. The new proposal also includes a $7 billion regulatory termination fee, as well as a $2.8 billion "breakup fee" that Warner Bros. would need to pay to Netflix if it withdraws from the existing agreement Currently, the merger agreement between Netflix and Warner Bros. Discovery, reached in December last year at $27.75 per share, remains valid and is expected to be completed in the third quarter of 2026. Senior analyst Gary Black predicts that Netflix will "come out on top" in the bidding war. Coinbase Global, ranked 17th, rose 13.52%, with a trading volume of $4.216 billion. Coinbase announced that it has opened stock and exchange-traded fund (ETF) trading to all U.S. customers, marking the company's official expansion from digital assets to traditional securities, moving towards the goal of becoming a "one-stop exchange." After this launch, users can buy and sell U.S. listed stocks and ETFs on the same platform as crypto assets.
