Thai share prices closed 0.17 percent lower on Thursday amid a lack of factors required to stimulate the market ahead of a long weekend, dealers said. The Stock Exchange of Thailand (SET) composite index shed 1.12 points to 648.92 and the bluechip SET 50 index was down 1.14 points to 455.17.
Gainers led losers 154 to 111 and 105 stocks were unchanged on trading of 1.32 billion shares worth 8.1 billion baht (193.8 million dollars).
Phadeumphob Songkrau from Bualuang Securities said the market lacked a number of incentive factors to stimulate it as companies released second quarter results in line with expectations.
"There were no significant factors, and investors delayed their investments ahead of a long weekend," he said. Thailand's markets are closed for a public holiday on Friday marking the beginning of Buddhist Lent.
