> The weighted index fell 2.52% at its low, while TSMC was down 0.22% by the 10 a.m. Taipei update.

Taiwan’s weighted stock index fell as much as 1,082.81 points early Nov. 5 in Taipei (Nov. 4 ET), as memory-chip and other AI data-center suppliers sold off while TSMC shares held nearly flat.

The index touched 41,866.10, down 2.52% from the previous close. By 9 p.m. ET Nov. 4 (10 a.m. Nov. 5 in Taipei), it had recovered to 42,203, down 745.43 points, or 1.74%. Taiwan’s over-the-counter index fell as much as 5.23%.

Memory-chip shares fell as much as 9.64%, 9.54% and 9.36% at their session lows. Circuit-board and cooling firms that supply AI data centers also recorded losses of up to 9.01% and 8.69%, respectively. Six companies across the wider AI supply chain touched their daily limit-down levels.

TSMC shares were down 0.22% by the 10 a.m. Taipei update. The selloff came amid concern that U.S. data-center construction could slow, though potential restrictions had not taken effect.
