World shares are mixed after Dow hits a new record, as some AI shares bounce back

World shares were mixed after the Dow Jones Industrial Average set a new record, with AI-related stocks showing mixed performance. Asian markets rebounded, including a 5.8% gain in South Korea's Kospi and significant rises in Samsung Electronics and SK Hynix, while European and U.S. indices showed varied movements. A weaker-than-expected U.S. jobs report raised hopes of slower inflation and potential Fed rate cuts, boosting investor sentiment.
