What Happened
Market Trading Dynamics: The Taiwan stock market saw significant volatility on the 27th, with trading volume surging to NT$924.68 billion despite a late-session pullback. While AI and PCB sectors remained central, the Formosa Plastics Group emerged as a major focus for investors.
Nanya Technology's Surge: Nanya Technology outperformed TSMC in daily trading value, reaching NT$45.35 billion and hitting a record high. Strong foreign institutional buying of over 30,000 shares underscored the bullish sentiment surrounding the stock.
Formosa Group Momentum: The strength in Nanya and Nanya Technology spilled over into the broader Formosa Plastics Group, with stocks like Formosa Plastics, Formosa Chemicals & Fibre, and Nan Ya PCB all posting gains. Increased foreign investment in these entities suggests a strategic rotation into the group.
