Thai shares dipped 5.5 per cent for two straight days after it shot up nearly 40 per cent this year.
Tisco Securities managing director Paiboon Nalinthrangkurn forecast that the SET index would dive to 500 points in the third quarter this year as investment sentiment will be depressed by the US Fed's hike in the key interest rate.
The current correction in the Thai stock market is in line with expectations as the US economy has not fully recovered yet and financial institutions in the US and Europe remain weak, he said.
An analyst at Asia Plus Securities said the SET's slump yesterday could be attributable to switching of money from the stock market to buy initial public offering (IPO) of Chinese companies worth about US$50 billion (Bt1.7 trillion) in the second half of this year.
The US government's plan to announce a stringent regulation to govern hedge funds also dampened the stock market, the analyst said.
Another analyst at a local broker said the Thai stock market's decline was in line with Wall Street and other regional stock markets.
A drop in oil price is also taken into account, the analyst said.
Investors should be prudent in profittaking as those who bought cheap stocks in the past couple of months might lock in profit, the analyst said.
They should hold cash to assess how the situation develops, the analyst said.
The next support and resistance levels are at 590 and 600 points, respectively.
Sombat Narawutthichai, secretary-general at the Securities Analysts Association (SAA), said the association is to revise upward the SET index target as several economic signs show improvement and capital is flowing into the stock markets.
The sharp increase in commodity prices, including freight rates, oil price and petrochemical products, would also be a blessing to companies' earnings, he said.
The next round of analyst survey will be conducted in early July.
According to the SAA's current consensus, the minimum and the maximum SET Index targets for this year are 535 and 582 points, respectively.
