The U.S. stock market opened strong on the 27th, with major indices showing significant gains after President Trump announced a delay on the 50% tariffs on the EU, boosting market sentiment.

According to the latest data, the Dow Jones Industrial Average opened up 368.85 points, reaching 41,971.92 points, a rise of 0.89%. The S&P 500 increased by 63.73 points to 5,866.55 points, a jump of 1.10%. The Nasdaq composite rose 275.64 points to 19,012.84 points, up by 1.47%, while the Philadelphia Semiconductor Index gained 79.39 points to settle at 4,781.76 points, an increase of 1.69%.

Initially, Trump proposed imposing the 50% tariffs starting June 1, but on Sunday, he extended the deadline to July 9 in response to a request from the EU. The stock market was closed on Monday in observance of Memorial Day.

Additionally, Tesla saw a decline in its recent sales performance in Europe, prompting some employees to issue an open letter calling for CEO Elon Musk to resign, citing his personal conduct as damaging to the company’s image. Musk stated he would focus on the company rather than politics, leading to a rebound of over 4% in Tesla's share price at opening.
