Some third-party sellers had even considered skipping Amazon Prime Day due to the tariff impact. However, with the tariff pause likely overlapping the mid-year sales event, those plans could now shift.

Market watchers say a more permanent deal between Washington and Beijing during this 90-day period could serve as a further catalyst for Amazon's (AMZN) stock, which has been under pressure this year. A final deal could help reverse the stock’s year-to-date losses and improve sentiment in the tech sector more broadly.

Meta (META)

Meta shares were just above the flatline, after climbing 8% on Monday, mirroring gains in other major tech stocks, as markets reacted positively to news that the US and China had reached an agreement to temporarily roll back tariffs.

The parent company of Facebook had been under pressure due to reduced advertising spend from Asia-based e-commerce firms. Last month, Meta’s (META) chief financial officer flagged a slowdown in ad revenue from the region, particularly from Chinese retailers. In 2024, more than 10% of Meta’s (META) total revenue originated from China.

Mark Mahaney, head of Internet research at Evercore ISI, said the rally was largely driven by easing concerns related to China.

“The only area of weakness they called out was China-based advertisers,” he said.

Although the latest trade deal restores temporary relief by cutting tariffs to 10% for a 90-day negotiation window, one key restriction remains in place.

The so-called de minimis loophole – previously allowing goods valued under $800 to enter the US tariff-free – was closed earlier this month and has not been reinstated. Chinese retailers had widely used the exemption to avoid duties on small packages sent to US consumers.

Boeing (BA)

Boeing’s (BA) shares were unexpectedly lower in pre-market trading, despite reports that China has lifted its ban on airlines accepting deliveries of Boeing (BA) aircraft. This decision follows a breakthrough in trade talks between the US and China after a month-long standoff.

According to Bloomberg, Chinese officials have instructed domestic airlines and government agencies to resume taking deliveries from Boeing, bringing an end of a freeze that had been in place since the escalation of the trade war.

The move comes just a day after the US and China announced a major de-escalation of their tariff conflict, with US duties on Chinese goods dropping from 145% to 30%, and China’s tariffs on American products falling from 125% to 10%.

The delivery ban on Boeing (BA) was part of the broader fallout from US president Donald Trump’s trade war, which also saw China block its airlines from purchasing aircraft parts and other equipment from US companies. At the time, Boeing (BA), one of the US’ largest exporters, was forced to return three 737 Max jets from China, and faced threats that large orders – such as those from Ryanair (RYA.IR) – could be cancelled.

In a letter to top US lawmakers, Ryanair (RYA.IR) CEO Michael O’Leary criticised Washington’s trade war with Beijing and warned that a “material” impact on the price of aircraft could prompt his company to take its business elsewhere.

M&S (MKS.L)

Retail giant Marks & Spencer (MKS.L) has confirmed that customer personal data was stolen in a significant cyber attack, though payment details, card information, and account passwords were not compromised. Investors appeared unfazed by the news, as shares were up in London.

CEO Stuart Machin stated that the data was accessed due to the "sophisticated nature of the incident," but assured customers that sensitive information, such as payment details, had not been affected. Machin wrote to customers to notify them of the breach, though he added that there was "no need for customers to take any action."

While the company did not disclose how many customers were impacted, Machin assured the public in a social media post that "there is no evidence that the information has been shared" and that it did not include any useable card or payment details.

To further secure customer accounts, Marks & Spencer (MKS.L) will prompt users to reset their passwords the next time they log in or visit their account. The retailer has also provided information on how to stay safe online.

However, Marks & Spencer (MKS.L) has been facing ongoing operational challenges since the breach. It has been unable to process any orders through its website or app since April 25 as it works to resolve the security issue.

Greg Zakowicz, senior ecommerce expert at Omnisend, said: “It will have been a bitter pill to swallow for M&S to admit that the recent cyber attack has put customer data at risk - particularly given the premium image the brand portrays.

“At the moment, the retailer’s advice is to change your account password and ensure it is unique and strong. But as an added layer of security, we would suggest that online customers enable two-factor authentication wherever possible and be cautious of phishing emails or suspicious calls that may use leaked data to appear legitimate.

“While it is reassuring that no payment data or passwords were reportedly compromised, the breach of personal information still poses serious risks—particularly in the form of phishing and identity fraud.
