On Friday, NVIDIA ranked first in US stock trading volume, closing down 4.89% with a trading volume of $49.113 billion. Technology stocks broadly faced pressure on Friday due to the latest tariff threats from Trump.

Additionally, Morgan Stanley recently held discussions with NVIDIA's management, maintaining its "Overweight" rating on the stock and setting a target price of $210. The firm noted that NVIDIA's market share in cloud capital expenditure is continuously expanding.

Tesla ranked second, closing down 5.06% with a trading volume of $45.39 billion. The National Highway Traffic Safety Administration (NHTSA) has launched an investigation into 2.88 million Tesla vehicles equipped with Full Self-Driving (FSD) systems. This action was triggered by over 50 traffic violation reports and multiple collision incidents.

NHTSA pointed out that while this driver assistance feature still requires drivers to remain attentive and intervene when necessary, it has "caused vehicle behavior that violates traffic safety regulations." Reports received by the agency show that Tesla vehicles with FSD activated have issues including running red lights and driving in the wrong direction when changing lanes.

This Preliminary Evaluation is the first step in a potential recall process - if NHTSA determines that vehicles pose unreasonable safety risks, a recall procedure may be initiated subsequently. According to statistics, the agency is currently reviewing 58 safety issue reports related to FSD, including 14 collision incidents and 23 injury cases.

AMD ranked third, closing down 7.72% with a trading volume of $25.386 billion. The chip sector broadly declined on Friday, but this stock gained over 30% for the week after the company announced a multi-billion dollar cooperation agreement with OpenAI this week to jointly develop AI data centers based on AMD processors, which is viewed as the most direct challenge to industry leader NVIDIA to date.

Under the terms of the agreement, AMD will provide hundreds of thousands of AI chips to OpenAI over a four-year agreement, while OpenAI receives AMD warrants allowing it to acquire up to 10% of the chip manufacturer's shares at $0.01 per share.

Moody's upgraded AMD's rating to A1 with a stable outlook.

Amazon ranked fourth, closing down 4.99% with a trading volume of $15.427 billion. The company will open its largest fulfillment center in the Pacific Northwest and plans to build another large e-commerce distribution center in Indiana. This new facility is located in Woodburn, Oregon, outside Portland, covering 3.8 million square feet - equivalent to four times the area of the nearby international airport, capable of storing millions of items. The center is equipped with advanced scanners, conveyor belt technology, and robots that can automatically extract and sort inbound and outbound orders and deliver goods to required locations.

Amazon plans to initially hire 3,000 employees for this facility.

Palantir ranked eighth, closing down 5.41% with a trading volume of $9.601 billion. Before Friday, the stock had risen for four consecutive trading days.

Broadcom ranked ninth, closing down 5.91% with a trading volume of $9.434 billion. Technology stocks broadly declined on Friday.

Alibaba ranked eleventh, closing down 8.45% with a trading volume of $8.021 billion. The stock fell 15.4% for the week.

Alphabet Class A stock (GOOGL) ranked twelfth, closing down 2.05% with a trading volume of $7.744 billion. The company faces stricter scrutiny from UK regulators, with its search engine potentially subject to regulation. The UK Competition and Markets Authority (CMA) issued a statement on Friday confirming that Alphabet's Google has "Strategic Market Status" in search services under the UK's new digital market competition regime.

TSMC ranked fourteenth, closing down 6.41% with a trading volume of $6.521 billion. The company announced on Thursday that September sales reached NT$330.98 billion, up 31.4% year-over-year and down 1.4% month-over-month. Third-quarter revenue increased 30% year-over-year to NT$989.9 billion, exceeding analysts' average expectation of NT$962.8 billion. Cumulative sales for the year reached NT$2.76 trillion, up 36.4% year-over-year.

TSMC is the preferred chip manufacturer for major AI accelerator designers including NVIDIA, AMD, and Broadcom. As global technology giants continue to invest billions in artificial intelligence, demand for high-end chips provides strong performance support for TSMC.

Coinbase Global ranked seventeenth, closing down 7.75% with a trading volume of $6.214 billion. Both Coinbase and Mastercard are advancing acquisition discussions for London-based stablecoin startup BVNK.

Robinhood ranked twentieth, closing down 8.85% with a trading volume of $5.758 billion.
