Apple Jumps To Record-High Amid Positive Catalysts

Shares of the iPhone maker clocked an all-time high of $334.68 on Thursday amid a series of positive catalysts for the company. 

China's cyberspace regulator on Wednesday approved the registration of Apple Intelligence for use on iPhones in the country, clearing a key regulatory hurdle for the long-awaited launch of Apple's AI features in the country. Under Chinese rules, companies must obtain approval for large language models and generative AI services before releasing them to the public. Apple Intelligence is expected to leverage AI models from Baidu and Alibaba. 

Meanwhile, HSBC upgraded AAPL stock to ‘Buy’ from ‘Hold,’ with a price target of $366, implying an upside of 10% from the stock’s last close. 

Apple has drawn increased attention in recent weeks after it announced hikes in prices for several products, including MacBooks, iPads, HomePods and Apple TV devices, fueling speculation that iPhone price increases could follow. Investors are also focused on the company's upcoming leadership change, with John Ternus set to succeed Tim Cook as CEO on Sept. 1.

AAPL stock has risen nearly 23% so far in 2026, while retail sentiment on Stocktwits was ‘bullish’ at the time of writing. 

AtaiBeckley Surges On Eli Lilly Acquisition

Shares of the psychedelics company surged to a yearly high of $7.22 after pharma giant Eli Lilly (LLY) confirmed its acquisition of AtaiBeckley.

Eli Lilly said that it will acquire all outstanding ATAI shares for $6.75 per share in cash, with shareholders eligible for an additional up to $2.50 per share if certain development and regulatory milestones are achieved, bringing the deal's total potential value to $9.25 per share. 

The cash offer represents a 25.9% premium to ATAI's Wednesday closing price, while the maximum consideration implies a 72.6% premium. The acquisition is expected to close in the third quarter (Q3) of this year. 

ATAI stock is up more than 84% this year. On Stocktwits, retail sentiment was in the ‘extremely bullish’ territory at the time of writing. 

UnitedHealth Jumps On Strong Earnings And Outlook

UNH stock touched a 52-week high of $461.62 in Thursday’s trading session after its second-quarter (Q2) earnings results blew past Wall Street estimates. 

The company posted revenue of $112.03 billion, up about 0.37% from $111.62 billion in the prior-year quarter. However, it beat Wall Street expectations of $110.9 billion, as per Fiscal.ai estimates. 

Meanwhile, net income came in at $5.48 billion, or $6.04 per share, compared with $3.41 billion, or $3.74 per share, in the same period a year ago.

The health insurer now expects 2026 adjusted earnings of $19.50 to $20 per share, up from its prior outlook of more than $18.25 per share, while maintaining its revenue guidance of more than $439 billion for the year.

The company attributed the better-than-expected results and higher full-year profit outlook to improved management of elevated medical costs and greater use of AI to streamline operations. 

UNH stock has gained nearly 26% so far in 2026, as retail sentiment improved from ‘bullish’ to ‘extremely bullish’ over 24 hours.
