Intensifying Chinese pressure on Taiwan is prompting some equity investors to buck the trend and exit Taiwan Semiconductor Manufacturing Co.

Martin Currie¡¯s Zehrid Osmani began winding down his TSMC position early last year and was fully divested by May. Shelton Capital Management¡¯s Bruce Kahn started selling TSMC shares last October and eliminated his stake by January, while Sydney-based hedge fund Plato Investment Management said it¡¯s ¡°nervous¡± about the world¡¯s largest foundry business.

At the same time, Martin Currie and Plato are among those finding an alternative in ASML, a crucial TSMC supplier.

These are bold bets when considering TSMC was the most widely held Asian stock among the world¡¯s 40 largest actively managed global equity funds as recently as July, according to Morgan Stanley¡¯s analysis. The company¡¯s stock is up 22% this year, outperforming ASML¡¯s near 12% gain.

Because the bulk of TSMC¡¯s operations are in Taiwan, it faces heightened geopolitical hazards, said Osmani, who helps oversee $3.2 billion as head of Martin Currie¡¯s global long-term unconstrained team. ASML, on the other hand, benefits from the ¡°technological fragmentation that the geopolitical risk brings,¡± he said.

While few fund managers expect military action, the situation remains high on their list of concerns, particularly because Taiwan is so important for U.S.-China relations. For some, including famed U.S. investor Warren Buffett, the possibility of conflict overrides enthusiasm about TSMC¡¯s market-dominating chip business.

By contrast, Netherlands-based ASML is relatively sheltered, with clients including Intel and Samsung Electronics The company provides lithography machines that are used in the production of chips.

David Allen, head of long-short strategies at Plato Investment, which manages 11 billion Australian dollars ($7 billion), avoids TSMC and said he¡¯s long ASML.

TSMC is ¡°an incredible company, but if things deteriorate from a sovereign perspective, who knows what¡¯s the right valuation for the company,¡± Allen said.

Bruce Kahn, who runs the $159 million Shelton Sustainable Equity fund, has sold TSMC. There¡¯s too much geopolitical friction that isn¡¯t currently reflected in the company¡¯s market valuations, similar to how investors weren¡¯t prepared for Russia¡¯s invasion of Ukraine, he said.

¡°People don¡¯t think anything is going to happen,¡± Kahn said. ¡°But that¡¯s the problem with risk, you don¡¯t think anything is going to happen until it does.¡±

These stock bets are facing challenges in panning out as expected. According to its latest earnings release, ASML¡¯s orders plunged in the third quarter and left the company more reliant on revenue from China. Meanwhile, TSMC shares climbed 1.8% Friday after its quarterly sales outlook exceeded analysts¡¯ estimates.
