Tripadvisor stock jumped 17% Thursday after Starboard Value revealed a more than 9% stake in the online travel company, according to a securities filing.

The position was valued at about $160 million as of Wednesday’s close.

Tripadvisor shares have been flat since the start of the year after plummeting more than 30% in 2024. Last year, the travel review and booking company said it created a special committee to explore potential options.

Starboard Value has gained a reputation for pushing for changes such as new CEOs and cost cuts by acquiring significant shares in companies.

Most recently, the firm settled a proxy fight with Autodesk, where it gained two board seats. It has previously pushed for changes at Tinder parent Match Group, pharmaceutical giant Pfizer and Salesforce.

The Wall Street Journal was the first to report the news late Wednesday.

Tripadvisor did not immediately respond to CNBC’s request for comment. Starboard declined to comment on the news.

Apple iPhone sales in China rose in the second quarter of the year for the first time in two years, Counterpoint Research said, as the tech giant looks to turnaround its business in one of its most critical markets.

Sales of iPhones in China jumped 8% year-on-year in the three months to the end of June, according to Counterpoint Research. It’s the first time Apple has recorded growth in China since the second quarter of 2023.

Apple’s performance was boosted by promotions in May as Chinese e-commerce firms discounted Apple’s iPhone 16 models, its latest devices, Counterpoint said. The tech giant also increased trade-in prices for some iPhone.

“Apple’s adjustment of iPhone prices in May was well timed and well received, coming a week ahead of the 618 shopping festival,” Ethan Qi, associate director at Counterpoint said in a press release. The 618 shopping festival happens in China every June and e-commerce retailers offer heavy discounts.

Apple’s return to growth in China will be welcomed by investors who have seen the company’s stock fall around 15% this year as it faces a number of headwinds.

U.S. President Donald Trump has threatened Apple with tariffs and urged CEO Tim Cook to manufacture iPhones in America, a move experts have said would be near-impossible. China has also been a headache for Apple since Huawei, whose smartphone business was crippled by U.S. sanctions, made a comeback in late 2023 with the release of a new phone containing a more advanced chip that many had thought would be difficult for China to produce.

Since then, Huawei has aggressively launched devices in China and has even begun dipping its toe back into international markets. The Chinese tech giant has found success eating away at some of Apple’s market share in China.

Huawei’s sales rose 12% year-on-year in the second-quarter, according to Counterpoint. The firm was the biggest player in China by market share in the second quarter, followed by Vivo and then Apple in third place.

“Huawei is still riding high on core user loyalty as they replace their old phones for new Huawei releases,” Counterpoint Senior Analyst Ivan Lam said.

Chinese tech giant Baidu has bolstered its core search platform with artificial intelligence in the biggest overhaul of the product in 10 years.

Analysts told CNBC the move was a bid to keep ahead of fast-moving rivals like DeepSeek, rather than traditional search players.

“There has been some small pressure on the search business but the focus on AI and Ernie Bot is a key move ahead,” Dan Ives, global head of tech research at Wedbush Securities, told CNBC by email. Ernie Bot is Baidu’s AI chatbot.

“Baidu is not waiting around to watch the paint dry, full steam ahead on AI,” he added.

Users are flocking instead to AI services such as ChatGPT or DeepSeek, which shocked the world this year with its advanced model it claimed was created at a fraction of the cost of rivals.

But Kai Wang, Asia equity market strategist at Morningstar, also noted that short video platforms such as Douyin and Kuaishou are also getting into AI search and piling pressure on Baidu.

To counter this, Baidu made some major changes to its core search product:

• Users can now enter more than a thousand characters in the search box, versus 28 previously;
• Questions can be asked in a more direct and conversational manner, mirroring how people now use chatbots;
• Users can ask questions through voice but also prompt the seach engine with pictures and files;
• Baidu has integrated its AI chatbot features, which enable users to generate photos, text and videos, into the product.

“This is more aligned with how people use ChatGPT and DeepSeek in terms of how they look for answers,” Wang said.

Outside of China, Google has also been looking to enhance its core search product with AI, highlighting how search has been under pressure from the burgeoning technology.

However, the Beijing-headquartered company has also faced intense competition from fellow tech giants like Alibaba and Tencent, as well as upstarts such as DeepSeek.

These companies have also been launching new models and infusing AI into their products and Baidu’s stock has fallen behind as a result. Baidu shares have risen around 2.5% this year, versus a 30.5% surge for Alibaba and a 20% rise for Tencent.

“This is a defensive and offensive move … Baidu needs to be aggressive and perception-wise show they are not the little brother to Tencent on the AI front,” Wedbush Securities’ Ives added.
