During the morning session, an analyst at Krungsri Securities said he expected the index to fluctuate between 1,265 and 1,280 due to a lack of positive sentiment.
In addition, he said, investors were delaying their investment until the US Federal Open Market Committee holds a meeting today and tomorrow.
“We expect the Fed to maintain the interest rate at 0 to 0.25 per cent and reveal its inflation target,” he said.
Moreover, he added, the SET will face volatility from mass sell-offs in stocks to mitigate risks from student protesters’ rally on September 19.
