BANGKOK, Oct. 8 (Xinhua) -- Thailand's stock investor confidence saw a continued improvement in September, driven by government stimulus measures and capital inflows, a survey showed on Wednesday.

The investor confidence index, which predicts market conditions over the next three months, stood at 153.62 last month, climbing from 120.22 in August and remaining in the "bullish" zone, according to the Federation of Thai Capital Market Organizations (FETCO).

Investor morale increased across all categories, with retail investors up 35.4 percent, proprietary investors up 19.7 percent, institutional investors up 28.2 percent, and foreign investors up 25 percent, the FETCO said in a statement.

Throughout September, the Stock Exchange of Thailand traded within a narrow range, buoyed by the new government's economic policy, said FETCO Chairman Kobsak Pootrakool.

However, both domestic and global economic slowdowns continued to weigh on investor sentiment, along with concerns over the Southeast Asian country's monetary policy and fiscal stability, Kobsak said.

Looking ahead, he pointed to the government's stimulus measures and fiscal budget announcements as factors that could affect credit risk evaluations, investor confidence, and the value of the baht currency, which could potentially impact the export sector. ■
