The Hang Seng opened 0.09% below its previous close, a fractional move that matters for its thinness: Hong Kong is waiting for a verdict from the mainland rather than making one of its own.

Chinese AI-linked listings have been a persistent source of selling pressure in recent sessions, so whether buyers step in for those names once Shanghai opens is the single clearest signal to watch.

The SSE Composite's opening data is not yet available, which is precisely why the Hang Seng is moving so little. Traders are effectively marking time until mainland flows give them something to trade against.
