1. XIAOMI-W Tops the Gainers with a 9.72% Rise as Xiaomi 17 Ultra Prices Rise by RMB 1,000

On October 9, XIAOMI-W (01810.HK) closed up 9.72% at HKD 25.960, the top gainer among AI concept stocks.

The company attributed the increase to rising memory chip costs; group president Lu Weibing has said the pace and scale of memory price increases far exceeded expectations.
