Taiwan Semiconductor Manufacturing stock surged Friday. However, American investors might not feel the full benefit of the rally, which was driven by Taiwanese regulators.
Taiwan's financial supervisory commission from Friday began to allow local equity funds and actively managed exchange-traded funds to invest up to 25% of their funds into listed companies with a weight exceeding 10% of the Taiwan Stock Exchange starting from Friday. Previously the limit for a single stock was 10%.
Taiwan Semiconductor, or TSMC, is the only company large enough to meet the weighting requirement, with its stock comprising more than 40% of the Taiwanese stock market by value. TSMC shares rose 5% to 2,185 New Taiwan dollars ($69.40), a record closing high.
One effect of the change is it might help narrow the persistent gap between the price of TSMC's shares in Taiwan and its American depositary receipts. The ADRs often trade at a premium due to their ease of access for international investors.
TSMC's ADRs were up 3.3% at $395.49 in premarket trading on Friday. As the ADRs represent five ordinary shares, that values a single TSMC share at around $79.10.
