Regulatory Easing Ignites Taiwan Stock Rally, TSMC Share Price Surges to NT$2,190 Hitting Record Peak

TradingKey - The policy of Taiwan's financial regulators to relax the ceiling on fund holdings served as the catalyst for a broad rally in Taiwan stocks, and TSMC ( TSM) shares reached an all-time high as a result.

On Friday, the Taiwan Financial Supervisory Commission announced plans to increase the investment limit for local equity funds and actively managed ETFs in a single stock from the original 10% to 25%.

The primary beneficiary of this regulatory shift is undoubtedly TSMC.

TSMC's intraday share price touched a high of NT$2,190 before closing at NT$2,185, a single-day gain of 5.05%; the TAIEX simultaneously closed up 3.23% at 38,932.40 points, making the Taiwan stock market the strongest performing major index in Asia that day.

Driven by the ongoing boom in the AI industry, TSMC's share price has continued to climb, now accounting for over 44% of the TAIEX and 13% of the MSCI Emerging Markets Index. The previous 10% single-stock holding limit prevented many local funds from fully positioning themselves in TSMC's rally, resulting in significant missed gains.

Vey-Sern Ling, Managing Director at Union Bancaire Privée, noted that after the holding limit is raised to 25%, local funds will have more capital to buy TSMC, which will also help narrow the discount between TSMC's Taipei-listed shares and its American Depositary Receipts (ADRs). Currently, a discount exists partly because converting Taiwan stocks into ADRs requires specific regulatory approval, whereas the U.S. market has no such restriction.

Despite the upbeat market sentiment, analysts also warned of potential risks. TSMC's weighting of over 44% in the TAIEX means that this policy adjustment will further exacerbate market concentration risk in Taiwan stocks. Analysts have previously voiced concerns that significant volatility in TSMC shares could drag down the overall market, and this increase in the holding limit will tighten the correlation between the individual stock and the broader index.

TSMC is not only a key semiconductor firm in Taiwan but also a pioneer and leader of the global semiconductor industry. As the world's largest wafer foundry, TSMC commands an overwhelmingly high market share in advanced process markets such as 5nm and 3nm.

The recently released Q1 2026 earnings results were particularly strong, with quarterly consolidated revenue reaching NT$1.134 trillion, net profit at NT$572.48 billion, and a record-breaking gross margin of 66.2%. Specifically, the revenue share from High-Performance Computing (HPC) increased significantly, with advanced processes at 7nm and below contributing the vast majority of revenue, primarily driven by the surge in demand for AI and HPC chips.
