Taiwan Weighted faces a four-day trading gap

Typhoon Champi will keep the Taiwan Stock Exchange closed on October 23. The October 26 Restoration Day substitute holiday extends the closure, with trading scheduled to resume on October 27, according to United Daily News.

The post-close TSMC equipment news adds a supply-chain issue to the information investors will assess when trading resumes. TSMC is seeking alternatives to rare-earth components because of concerns about possible disruption from Chinese export controls, Reuters reported.
