II. Strong Sectors

· Fiberglass Cloth and PCB Materials (AI Platform Upgrade Causes Supply Tightness): Surging demand for AI servers and high-end substrates has caused extreme tightness in high-frequency, high-speed low-DK fiberglass cloth. Fu-Chi (1815-TW) surged to its daily limit at NT$18.50, while Taiwan Glass (1802-TW) and Jianrong (5340-TW) also hit their daily limits.

· Memory ICs and Manufacturing (Super Cycle with Rising Volumes and Prices): Global manufacturers shifting capacity to HBM have caused spillover shortages in standard and niche memory, driving spot and contract prices higher. Nanya Technology (2408-TW) reported its 8th consecutive monthly revenue record and surged to its daily limit. Winbond (2344-TW) jumped 9.79%, while PSC (3006-TW) and Etron (5351-TW) also hit their daily limits.

· IC Substrates and ABF Substrates (Advanced Packaging Demand Doubles): 2.5D/3D advanced packaging is driving rapid consumption of high-layer, large-area ABF substrates, keeping utilization rates high. Nanya PCB (8046-TW) reported its highest revenue in 43 months, surging to its daily limit and reclaiming the NT$1,000 mark. Kinpo (3189-TW) hit its daily limit, and Unimicron (3037-TW) rose 6.82%.

III. Weak Sectors

· Automotive and Auto Components (High Interest Rates and Seasonal Slump): High interest rates dampened loan demand, and summer plant maintenance affected sales. Yulon (2201-TW), Hotai Motor (2207-TW), and Foxconn EC (1533-TW) saw minor corrections.

· Financials and Banks (Fund Rotation Back to Electronics): Risk-off funds rotated into electronics, leading to profit-taking. E.SUN Financial (2884-TW),兆豐金 (2886-TW), and Cathay Financial (2880-TW) saw narrow-range corrections.
