Uber rises after Ackman discloses stake

Bill Ackman, avid X user and CEO of the hedge fund Perishing Square, disclosed Friday morning that his firm started buying shares of Uber this year and now owns 30.3 million shares, worth about $2.3 billion at the current share price.

Uber stock shot up about 9% on Friday and is up about 17% in the past week. This comes after the company reported earnings and guidance on Wednesday that left investors unimpressed.

Ackman said in his X post that Uber is one of the best managed and highest quality businesses in the world. Uber CEO Dara Khosrowshahi responded welcoming Ackman and noting, Bill has called me many times with observations and suggestions re our service.

Six Flags pops after reiterating its guidance as theme park attendance rebounds

Six Flags shares rose more than 7% today after the company reported a rebound in attendance and early season-pass sales heading into the fall. The nine-week period ending August 31 saw 17.8 million guests, up about 2% from the same stretch in 2024, with stronger momentum in the final four weeks. 

More importantly, Six Flags reaffirmed its full-year adjusted EBITDA guidance of $860 million to $910 million, showing confidence that its cost and operations strategy can stay strong for the duration of the year. Riding that wave, Six Flags also said early 2026 season pass unit sales are pacing ahead of last year, and average season pass prices are up around 3%.

The good vibes come despite a drop in in-park per capita spending, especially from admissions, where promotions and changes to attendance mix (which parks or days guests visit) have weighed. Earlier this week, the amusement giant extended a new agreement that extended its position as the exclusive amusement park partner for Peanuts™ in North America through 2030.

Despite the rally, Six Flags shares are down around 52% year-to-date.

Rivian turns red on the year, squeezed by a recall and the looming end of the EV tax credit

Shares of EV maker Rivian are down more than 5% on Friday following the company’s recall of 24,214 vehicles due to a software issue. The stock move erases Rivian’s year-to-date gain and turns the company negative on the year.

Rivian’s 2025 model year R1S and R1T are affected by the defect, which was identified after a vehicle’s hands-free highway assist software failed to identify another vehicle on the road, causing a low-speed collision. Rivian said it’s released an over-the-air update to fix the issue.

The recall marks Rivian’s fifth this year, affecting nearly 70,000 of its vehicles.

Rivian’s shares are down more than 20% from their 2025 high, which came prior to the passage of President Trump’sbig, beautiful bill.” Through the legislation, the $7,500 EV tax credit is set to expire at the end of the month.
