Why is Oruka Therapeutics stock sliding today?

Oruka Therapeutics' stock fell 2.5% in pre-market trading after releasing positive but expected Week 28 trial data, with 71.4% of patients achieving complete skin clearance. The company's Chief Medical Officer highlighted the potential of ORKA-001. A pre-planned insider sale of 10,000 shares and a cautious market backdrop also contributed to the decline. Oruka's Price-to-Sales ratio remains high, reflecting growth expectations. The company plans to share more data in December 2026 and Q4 2026.
