Amylyx, Duolingo and Profusa jump premarket, Baidu falls after Q2 results

Baidu shares declined in premarket trading following the release of Q2 2026 financial results. The company reported an earnings miss, primarily driven by a 19% decrease in advertising revenue. While other stocks like Amylyx, Duolingo, and Profusa saw premarket gains, Baidu faced downward pressure. Market analysts are now evaluating whether the current price drop presents a buying opportunity or if investors should remain cautious given the reported decline in key revenue streams.
