On the mainland, the Shanghai Composite Index closed up 12 points, or 0.33 percent, at 3,822 on turnover of one trillion yuan.

The Shenzhen Component Index was 437 points, or 3.25 percent, higher at 13,885 on turnover of 1.2 trillion yuan.

"We expect AI to reassert market leadership into August," analysts at JPMorgan said in a note.

The recent sharp decline in AI-linked cohorts is a healthy rotation rather than the end ⁠of the cycle, and it may ultimately create a more attractive entry point in August, they added.

In Seoul, the Kospi ended an up-and-down day with gains of 101 points, or 1.62 percent, at 6,358 as chip giants SK Hynix and Samsung – which have been the poster boys of a month-long AI-themed rout – ticked higher. (Agencies)
