Singapore stocks finish weaker after bank selloff

US President Donald Trump's promise of a "phenomenal" tax plan may have driven Wall Street to new highs on Monday but here, a bank selloff on Tuesday after OCBC reported its latest results, led to a 39.16 points or 1.3 per cent loss for the Straits Times Index at 3,072.47, its biggest single-day drop of 2017.

Volume was above average at 3.3 billion units worth S$1.47 billion with continued rotational playing of penny stocks providing a significant outlet for the market's speculative energies. The advance-decline score excluding warrants was 176-310.
