Jaguar Health’s stock skyrocketed by 1190.64%, closing at $34.46. The stock reached an intraday high of $41.53 and a low of $2.75, with a 52-week high of $1,280.95 and a low of $2.37. In after-hours trading, the stock rose 5.19% to $36.25.
The surge follows the company’s announcement that it received fee waivers from the Food and Drug Administration, a significant development for the company.
Jaguar Health said the FDA waived the fiscal 2027 Prescription Drug User Fee Act fee for Mytesi, its approved treatment for noninfectious diarrhea in adults with HIV/AIDS, reducing regulatory costs associated with the drug. The company also received a separate FDA fee waiver for Canalevia-CA1, its conditionally approved treatment for chemotherapy-induced diarrhea in dogs, while Jaguar continued preparations for a potential 2027 NDA filing for crofelemer in microvillus inclusion disease.

The rise came after IonQ announced a breakthrough in quantum computing, demonstrating a real-time quantum error correction decoder. The company demonstrated that a single standard processor could perform quantum error correction in real time, eliminating a bottleneck that had forced quantum computers to pause while errors were corrected.
Viking Therapeutics Inc. (NASDAQ:VKTX)
Viking Therapeutics saw its stock jump by 35.67%, closing at $40.85. The stock’s intraday high was $41.73, with a low of $36.34. The 52-week high and low were $43.15 and $24.78, respectively. The shares rose 2.02% to $41.68 in after-hours session.
Viking Therapeutics reported positive topline results from its VK2735 maintenance trial, with patients retaining up to 97% of their weight loss on biweekly dosing and up to 90% on monthly dosing, compared with 61% after switching to placebo.
During the 21-week induction phase, patients lost 16% to 19% of their body weight, while VK2735 showed a favorable safety profile with gastrointestinal side effects comparable to placebo.
Xanadu Quantum Technologies Ltd (NASDAQ:XNDU)
Xanadu Quantum’s stock fell by 21.57%, closing at $5.78. The stock’s intraday high was $6.18, and the low was $5.32, with a 52-week high of $42.44 and a low of $5.32. In after-hours trading, the stock gained 2.58% to $5.93.
Xanadu Quantum shares fell in the regular session as the company’s 180-day post-IPO lockup expired, unlocking approximately 255 million additional shares compared with only about 43 million shares previously available for trading. The sharp increase in potential share supply added selling pressure as early investors, employees and other restricted holders gained the ability to sell their shares.

Grab Holdings’ stock rose by 8.93%, closing at $3.17. The stock reached an intraday high of $3.21 and a low of $3.04, with a 52-week high of $6.62 and a low of $2.74.
The increase followed significant stock purchases by two top executives, indicating confidence in the company’s future. CEO Anthony Tan’s purchase of over 10 million shares was a notable transaction.
