I. Market Analysis

The TAIEX index retreated slightly by 214.90 points to close at 44,396.70 points, pressured by profit-taking in heavyweight stocks such as TSMC and MediaTek. However, the index remained securely above both the monthly and quarterly moving averages, preserving a healthy bullish moving average structure. The TAIEX’s intent to stabilize above moving averages and defend the quarterly line is clear. In contrast, small-to-mid cap stocks in the OTC market performed exceptionally well, surging 1.99% to close at 391.37 points, showcasing strong recovery momentum. Across all markets, the three major institutions collectively bought NT$8.903 billion, with foreign investors and trust funds jointly increasing positions in high-quality small-to-mid cap technology stocks.

II. Strong Industries

• Memory & Niche ICs (Capacity Shift Driving Price Increases):

Benefiting from the global top three original manufacturers shifting production capacity fully toward HBM and high-end DDR5, traditional DRAM and NAND Flash face severe capacity displacement. Coupled with a sudden surge in rush orders for Edge AI devices and industrial control applications during peak season, both contract and spot prices have risen strongly. Key stocks include Phison (8299-TW), which hit the daily limit up at NT$2,025.00; ADATA (3260-TW), up +6.31% to NT$421.00; and Winbond (2337-TW), also hitting limit up at NT$129.00. Among niche ICs, Etron (3006) soared +7.95% to NT$258.00, Silicon Integrated Systems (5351-TW) rose +6.74% to NT$103.00, and Aptina (6531-TW) gained +5.26% to close at NT$900.00.

• Copper Clad Laminate (CCL) (AI Server Consumption Doubles):

Driven by widespread adoption of high-layer-count, large-area board designs in global AI servers and high-performance computing (HPC), consumption of high-end Ultra Low-DK copper clad laminates has doubled. This has significantly boosted product pricing and gross margins for leading manufacturers. Industry leader ITEQ (6213-TW) surged on heavy volume to hit the daily limit at NT$375.00; TTM Technologies (6274-TW) rose +4.08% to NT$1,530.00; Taigene Biotech (2383-TW) held firm at a high level, closing at NT$5,305.00; and Dynapack International - KY (6672-TW) climbed +4.97% to NT$232.50.

• Thermal Module & AI Servers (Mass Production of Liquid Cooling):

New-generation high-power AI chips are widely adopting liquid cooling solutions, resulting in explosive growth in shipments of cooling tanks, CDUs, and cold plates. Demand for high-end rails has also warmed simultaneously. Both Foxconn Interconnect Technology (3324) and Sunonwealth Electric Machine (2421-TW) reached the daily trading limit. AcBel Polytech (3017-TW) surged +7.69% to NT$2,940.00, while Chuan-Hu Circuit Board (2059-TW) skyrocketed +6.65%, breaking the NT$10,000 barrier to close at NT$10,100.00.

III. Weak Industries

• Financial Conglomerates & Securities (Capital Rotation Pullback):

With the TAIEX consolidating at high levels, market capital has extremely concentrated into small-to-mid cap AI tech stocks, causing financial and securities sectors to suffer capital displacement. Institutional investors took profits and adjusted risk positions. Fubon Financial (2881-TW) fell -2.70% to NT$126.00, Cathay Financial (2882-TW) declined -2.99% to NT$97.50, and Mega Financial (2886) dropped -1.76% to NT$50.30; Yuanta Securities (6005) edged down -0.86% to NT$34.55, Uni-President Securities (2855-TW) slipped -1.64% to NT$45.10, and Fu-Pon Securities (6026-TW) fell -1.77% to NT$13.85.

• Air Passenger Transport (Seasonal High Already Priced In):

The summer travel season’s upside potential has already been fully reflected in earlier stock prices. Market focus has now shifted to fourth-quarter freight trends, with capital rotating toward high-flexibility electronics stocks. Evergreen Marine Corp. (2618-TW) dipped -1.26% to NT$43.25, China Airlines (2610-TW) fell -1.99% to NT$22.15, and Starlux Airlines (2646-TW) declined -0.70% to NT$21.30.
