TSMC shares fell 1.64% to close at NT$2,395 on August 14, slipping below the NT$2,400 threshold. Investors triggered the decline through profit-taking following a recent surge in the stock's value. A large sell order during the final auction intensified losses and contributed to a broader downturn in the Taiwanese stock market.
The decline occurred despite a U.S. SEC filing showing record performance for the first half of 2026. Net income for the six months ending June 30 nearly doubled to NT$1.28 trillion from NT$758.23 billion in 2025. Revenue for the same period reached NT$2.40 trillion.
Market sentiment favored short-term consolidation over the positive financial results.
