Maersk Stock Soars, Reflecting Benefits of Eased Trade Tensions
After the US and China reached a tariff suspension agreement in Geneva, global markets generally rose. As a leading company in global container shipping, Maersk benefited from the easing of trade tensions, with its stock price surging by 14% on December 12th, making it the largest gainer in the Stoxx 600 index for the day. Maersk controls about 14% of the world's container shipping capacity and operates 60 ports, making its business highly dependent on international trade flows and extremely sensitive to changes in US-China tariff policies.
European stock markets also rose in tandem, with the Stoxx 600 index up 0.8% in early trading, Germany's DAX index up 1.1%, and France's CAC 40 index up 1.3%. The market generally views this 90-day tariff suspension agreement as providing breathing room for the global economy.
Novo Nordisk Stock Plummets, Drug Pricing Policy as a Source of Pressure
In stark contrast to Maersk, Danish pharmaceutical giant Novo Nordisk's stock fell by 8.6% on the same day, becoming the biggest loser in the Stoxx 600 index. This decline was mainly due to US President Trump's announcement of a policy to significantly lower prescription drug prices, which directly impacted Novo Nordisk, whose main products are the weight loss drug Wegovy and diabetes medications.
Novo Nordisk's market value has decreased by one-third this year, losing its status as the most valuable company in Europe. The Danish stock market has also been dragged down, with a cumulative decline of 3.4% this year. Concerns about US drug price reforms have further spread to other European and US pharmaceutical companies, putting pressure on the overall pharmaceutical sector.
Trump Claims Apple and TSMC Will Invest Heavily in the US
Against the backdrop of a trade war pause, US President Trump told the media in the Oval Office that he had spoken with Apple CEO Tim Cook that morning, claiming that Apple would invest up to $500 billion in the US to build multiple factories. Trump emphasized, "He (Cook) will increase his numbers. $500 billion, and he will build many factories for Apple in the US."
Apple's stock opened higher and continued to rise, with midday gains nearing 6%, aligning with the broader US stock market. The market generally believes that Apple benefits from the tariff suspension and the favorable policy of investing in the US, boosting investor confidence.
Additionally, Trump reiterated TSMC's investment amount, stating that TSMC's investment in the US had been "increased" from the original $165 billion to $300 billion. Although TSMC has not officially confirmed this figure, its wafer plant construction and expansion plans in Arizona are underway, covering advanced processes and AI server chip production.
Taiwanese Companies Reassess Supply Chain Layout
At the "Select USA Investment Summit" held in Maryland, Executive Yuan Secretary-General Kung Ming-hsin noted that 138 Taiwanese companies and 183 representatives participated, marking the largest turnout in history. Kung stated that many Taiwanese multinational companies are considering shifting part of their supply chain to the US in response to US tariff policies.
He noted that Taiwan's foreign investment was mainly concentrated in mainland China in the past, but with the US-China trade war and the rise of the AI industry, Taiwan's export share to China has fallen to less than 10%, while the US has become Taiwan's largest investment destination. Kung emphasized that this reflects the deepening and stability of Taiwan-US economic cooperation.
Additionally, according to Dun & Bradstreet (D&B), Taiwanese companies are actively using data tools to optimize supply chain transparency and ESG compliance to meet the high standards required by the US market for suppliers. These strategies position Taiwanese companies as key partners in the rebuilding of US manufacturing.
