Taiwan's stock market opened in the green Thursday, a mildly positive start for investors in one of Asia's biggest tech-heavy markets.

• The Taiwan Stock Exchange's main index opened up, adding to its position near record territory.
• Early turnover was light, so the gain rests on thin trading rather than heavy buying.
• Taiwan's index is dominated by chipmakers, so it tends to track global demand for AI and semiconductors.
• Weather is a wildcard: a sea warning is out for Typhoon Saudel, and a magnitude 5.2 quake hit the island's southeast.

Outlook: The open sets a positive tone, but the day's direction will depend on chip demand and how the storm affects the island.
