TSMC shares fell on June 24, 2026, amid a global sell-off of semiconductor and technology stocks. Investors engaged in widespread profit-taking following heavy losses in U.S. chip markets.
The U.S. International Trade Commission is currently investigating TSMC over patent infringement complaints. A preliminary ruling expected by the end of June 2026 could result in a U.S. import ban on key chips.
Additional pressure stems from revenue growth falling short of internal projections. High capital expenditures are also fueling investor concerns regarding potential margin compression.
