A-share fiber-optic sector rallied: Yangtze Optical Fibre hit the daily price limit and extended to a fresh record high; Sanfu and Tefa Information earlier hit limit-up; Han's Laser rose over 9%; Changjiang Communication and FiberHome also advanced.

Nikkei 225 dipped modestly on Tuesday as traders paused after an eight-day rally. Persistent buying in AI and semiconductor stocks drove the recent surge, pushing the index to fresh records — it first cleared 71,000 two sessions earlier and breached 72,000 on Monday. The 14-day RSI reached 73 and eased to 70.7 on Tuesday, a level typically read as overbought and prone to a pullback. Mitsui Sumitomo DS Asset Management chief market strategist Masahiro Ichikawa said mild profit-taking was evident and selling pressure appeared to be building after the extended gains.
