Taiwan’s UMC beats TSMC with 11% stock gain

United Microelectronics Corp. (UMC) has outperformed Taiwan Semiconductor Manufacturing Co. (TSMC) in stock performance this year.

UMC’s stock has risen by 11% while TSMC’s shares have declined by 3.7%.

UMC’s dividend yield, which exceeds 6%, has attracted interest from Taiwan’s high-dividend exchange-traded funds (ETFs) that manage over US$44 billion in assets.

In contrast, TSMC’s dividend yield is below 2%.

This has resulted in its absence from the top holdings of these funds.

Taiwan’s three largest yield-focused ETFs have received around US$10 billion in inflows this year, with UMC listed as one of their top 10 holdings.

1️⃣ The yield paradox in semiconductor investing reveals divergent growth strategies

The contrast between TSMC and UMC demonstrates a fundamental investment dynamic playing out in semiconductors, focusing on yield versus growth positioning.

UMC’s 6% dividend yield versus TSMC’s sub-2% reflects their dramatically different profit profiles, with TSMC’s 41.69% profit margin being more than double UMC’s 18.91% margin 1, 2.

This yield differential explains why Taiwan’s yield-focused ETFs prefer UMC. However, TSMC reinvests substantially more profits into expansion and advanced manufacturing processes to maintain its technological edge.

TSMC’s aggressive capital allocation strategy is evidenced by its leadership in advanced manufacturing, with the company planning to mass-produce its 14A (1.4nm) process by 2028, positioning it for the projected $1 trillion semiconductor market by 2030 3, 4.

While UMC benefits from yield-seeking capital flows in the near term, TSMC’s reinvestment approach aligns with the industry’s projected 7-9% compound annual growth rate from 2025-2030, particularly in advanced nodes where TSMC dominates 5.

The market is essentially pricing two different business strategies: UMC’s higher current returns versus TSMC’s long-term growth investments, creating the paradoxical performance pattern observed in their stock prices.
