Tech Stocks Lead Gains, Major U.S. Stock Indices Rise for Fourth Consecutive Day
On Friday, April 25, all three major U.S. stock indices closed higher, continuing the strong upward trend of the week. The S&P 500 rose by 40.44 points, or 0.74%, closing at 5525.21; the Nasdaq increased by 216.90 points, or 1.26%, closing at 17382.94; and the Dow Jones Industrial Average edged up 20.10 points, or 0.05%, closing at 40113.50.
For the week, the S&P 500 gained 4.59%, the Nasdaq surged 6.73%, and the Dow Jones rose 2.46%. This marks the third straight week of gains for all three indices, indicating a continued warming of market sentiment.
Tech stocks were the primary drivers of this rally. Alphabet (GOOGL) reported better-than-expected first-quarter earnings and announced a $70 billion stock buyback plan, with its stock rising 1.68%. Meta Platforms (META) rose by 2.65%, Microsoft (MSFT) increased by 1.17%, Amazon (AMZN) climbed by 1.31%, and Apple (AAPL) edged up by 0.44%. The Philadelphia Semiconductor Index also rose by 1.03%, closing at 4251.61, reflecting a simultaneous strengthening of chip stocks.
Tesla's Stock Soars Nearly 10%, Becomes the Focus
Tesla (TSLA) became one of the most notable stocks in the market this week. Boosted by the Trump administration's announcement to relax regulations on autonomous vehicles, Tesla's stock surged 9.8% in a single day, closing at $284.95, marking its best weekly performance since November last year.
Tesla's stock rose approximately 18% this week, closing higher for several consecutive days. This rally reflects not only market optimism about the relaxation of autonomous driving policies but is also positively influenced by CEO Elon Musk's commitment to focus on company operations and reduce involvement in government affairs.
Additionally, foreign media reported that Tesla has started refunding deposits to Indian consumers who pre-ordered the Model 3 in 2016, which the market sees as Tesla's imminent official entry into the Indian market, further boosting investor confidence.
Trump Administration Eases Autonomous Vehicle Regulations, Promotes Industry Innovation
This week, the Trump administration announced it will relax federal safety standards for autonomous vehicles and simplify accident reporting requirements. The National Highway Traffic Safety Administration (NHTSA) stated that it will allow some autonomous vehicles that do not meet traditional safety standards (such as those without rearview mirrors) to operate on U.S. roads and will streamline reporting requirements for incidents related to autonomous systems, retaining only critical safety information.
U.S. Secretary of Transportation Sean Duffy stated that this policy adjustment aims to simplify bureaucratic procedures, establish a nationwide standard, promote innovation in the U.S. autonomous vehicle sector, and enhance technological competitiveness with China.
This relaxation measure aligns with the direction long championed by Tesla CEO Elon Musk. Musk has repeatedly called for the U.S. government to establish unified regulations for autonomous vehicles to replace the current system where states and local governments operate independently. He believes that a fragmented regulatory system impedes the scaling and commercialization of autonomous technology.
Currently, Tesla has over 2 million vehicles in the U.S. equipped with driver assistance and autonomous driving software. This policy relaxation will aid Tesla in accelerating its Robotaxi plan, especially the autonomous taxi fleet expected to launch in Austin, Texas, in June.
Market Reaction and Background
This policy adjustment is viewed as a significant step in the U.S. government's accelerated positioning in the global autonomous vehicle race. As China rapidly advances in the autonomous technology field, the U.S. government hopes to create a more favorable environment for domestic companies like Tesla and Waymo by relaxing regulations.
However, the policy has also sparked concerns among some safety advocacy groups. They argue that relaxing safety standards and simplifying accident reporting could reduce transparency and safety oversight of autonomous vehicles, increasing potential risks.
Nevertheless, based on market reactions, investors generally view this move positively, believing it will help advance the commercialization of autonomous technology and enhance the U.S.'s position in global technological competition.
