The Singapore stock market tumbled on Tuesday, ahead of keenly awaited remarks by United States Federal Reserve chairman Ben Bernanke on Wednesday night.
Investors grabbed the opportunity to lock in recent gains, sending the benchmark Straits Times Index dipping 11.86 points, or 0.37 per cent, to 3,224.96.
Trading centred mostly around the penny stocks, with 3.3 billion shares worth just $976.5 million changing hands.
Stock markets around the world have been dancing to Mr Bernanke's tune since late May.
Regional markets were mildly higher, with benchmark indices in Tokyo, Hong Kong and Shanghai showing gains.
