What happened on 6 November 2026

The sell-off was broad and fast, which is why it drew attention far beyond Taiwan. Some headlines cited a 4.47% decline, while closing data showed 4.51%; that difference may reflect rounding, timing, or different data feeds.

For Indian readers, the move is relevant because Taiwan is deeply linked to global electronics and chip supply chains that affect technology stocks and manufacturing sentiment worldwide.

Why the market fell

TSMC was central to the fall. Its shares reportedly hit the daily limit down at NT$2,020, and MediaTek also reached its limit down.

Analysts also cautioned that leveraged investors could face margin calls, which could lead to additional forced selling.

This is also a reminder that semiconductor and AI-related stocks can react sharply to changes in U.S. demand expectations. Moves like this can affect sentiment in Indian technology, manufacturing, and export-linked stocks even when the event happens overseas.

What to watch next

Investors will also watch whether TSMC and other large semiconductor names recover or remain under pressure. Because Taiwan is a major supplier base, the next sessions may influence broader Asian market sentiment too.
