Pcl, the No. 1 construction company, tumbled 0.95 baht, or 14 percent, to 6. Bangkok Metro Pcl, operator of the capital's subway, plunged 0.06 baht, or 4.6 percent, to 1.25. The stock is the first to debut after the coup. The company earlier this month raised 3.6 billion baht in its initial public offering. Buying opportunity Further declines may be limited because the coup helped resolve a political deadlock, analysts said. The end of the stalemate will enable an interim government to quickly draft a new government budget, central bank Governor Pridiyathorn Devakula said. "Political volatility, including coups, are nothing new for Thailand," Merrill Lynch & Co.'s strategists Spencer White, Willie Chan and Stephen A. Corry said in a note to investors dated yesterday. "This time investors should be encouraged by the fact that the uncertainty surrounding Thaksin's tenure has been removed." Merrill Lynch kept its "overweight" rating on Thai stocks. Threadneedle Investments, a London-based money manager owned by American Express Co. that oversees more than 70.4 billion pounds ($133 billion) of assets, said it may add Thai stocks. "Without the removal of Thaksin, the instability could have dragged on for a long time and there could have been an escalation in protests and violence," said Maxine Cuffe, an emerging markets fund manager at the group. "Ideally, the military will transfer power quickly." "This provides a tactical buying opportunity," Christopher Wood, global equities strategist at CLSA Ltd. in Jakarta, wrote in a report published yesterday. Wood recommended investors buy more Thai stocks and suggested the coup will help resolve a political standoff that hurt the economy. "The key point for the stock market is that the months-long stalemate had to be broken," he wrote. "The political impasse was clearly impacting both business and consumer confidence."

Mark Mobius, who oversees about $30 billion in emerging market equities at Templeton Asset Management, said in an interview from Shanghai."We're not that concerned because we've seen this before" In a written note this morning, Mobius said "We remain of the view that the long-term outlook for Thailand is good." He said if prices drop, he would look to buy shares in bank, natural resource and real estate companies.
