European stocks rose on Friday, with the STOXX 50 gaining 0.8% after hitting a four-month low, supported by easing oil prices and bond yields. Brent crude retreated from recent highs after US President Donald Trump said Washington would not launch an attack on Iran before the November midterm congressional elections, citing productive talks aimed at ending the conflict. Meanwhile, strong demand at a US 30-year Treasury bond auction helped push yields lower, suggesting investors remained willing to buy long-dated government debt despite the recent selloff. AI-related sentiment also strengthened following reports that OpenAI expected its annualized revenue to reach or exceed $70 billion by year-end, helping ease concerns triggered by earlier reports that revenue was running $20 billion below previously indicated levels. Separately, LSEG IBES data showed European third-quarter earnings growth expectations rising to 21%, from 19.4% a week earlier, ahead of the earnings season.
