Touch-module maker GIS-KY jumped to its daily limit as money piled into its move into optical communications — good news for holders, and a sign where Taiwan's AI money is flowing next.

• GIS-KY locked at limit up within ten minutes of the open, with a huge queue of unfilled buy orders still waiting.
• The company is spending far more than planned this year, most of it on laser light-source packaging and testing gear for high-end optical chips.
• Its new Vietnam plant is nearly built and should start making some products around the turn of the year, giving it two growth lines next year: touch modules and optical parts.
• Analysts see 2026 as a quiet rebuilding year while low-margin old products are phased out, with much bigger profits possible by 2027 and 2028.
• The stock still trades close to its book value, suggesting the market has not repriced it away from being a fading touch-panel supplier.

Meanwhile the wider Taiwan market opened weak after the Mid-Autumn break, slipping below 48,000 as MediaTek sold off hard, while display makers AUO and Innolux drew the heaviest trading. Regional markets fell too, with Korea down sharply. Regulators are also preparing a cross-checking system for brokerage and bank credit at the end of October, meant to stop investors stacking up borrowed money across several lenders — a change some warn could trigger a forced-selling scare like Korea's earlier this year. Adding to nerves, US bond market swings and pressure on bank stocks have revived talk of an "October curse," though foreign money flowed heavily back into Taiwan last week on hopes for a strong fourth quarter.

Outlook: Traders expect Taiwan stocks to stay choppy in the short term but push higher into year-end, with AI optical and display names leading.
