TSMC 0.43 Drop and 28th Trading Volume Rank Underscore 2nm Tech Dominance Amid Supply Chain Resilience

On August 28, 2025, TSMC (TSM) closed with a 0.43% decline, trading at a volume of $2.01 billion, ranking 28th in the day’s market activity. The stock’s performance reflects ongoing market dynamics tied to its strategic position in the semiconductor industry.

Apple’s reported securing of nearly half of TSMC’s initial 2nm chip production capacity has positioned the foundry as a key player in advanced semiconductor manufacturing. This exclusive arrangement not only solidifies TSMC’s role in Apple’s supply chain but also underscores its ability to navigate potential disruptions from proposed U.S. tariffs on imported chips. Analysts note that TSMC’s Arizona-based production expansions could further insulate it from trade risks, aligning with broader U.S. investment incentives.

Recent legal challenges, including an indictment of three individuals for allegedly stealing TSMC’s trade secrets to benefit Tokyo Electron, have raised concerns about intellectual property security. While TSMC has denied organizational involvement in the case, such incidents highlight vulnerabilities in safeguarding cutting-edge technology. Meanwhile, the company’s decision to phase out 6-inch wafer production and consolidate 8-inch capacity signals a strategic shift toward higher-margin, advanced-node manufacturing.

Positive sentiment persists among analysts, who cite robust demand for AI-driven chips and TSMC’s leadership in 2nm technology. The firm’s 2024 financial results showed a 33.89% revenue increase to $2.89 trillion, with earnings rising 36% to $1.16 trillion. Despite short-term volatility, long-term fundamentals remain strong, supported by its dominant market share in advanced-node production and expanding U.S. operations.
