SINGAPORE shares ticked higher on Tuesday afternoon, with the Straits Times Index gaining 0.8 per cent, or 25.38 points to 3,164.53 as at 1.02pm. 

Gainers edged out losers slightly at 155 to 149, after about 449.4 million shares worth S$588.4 million changed hands. This turnover was significantly higher than Monday's churn of about 387.9 million shares worth S$318.6 million, shortly after the midday break.

This comes after Temasek on Monday made a surprise S$4 billion partial offer for Keppel, reigniting speculation that there might be a consolidation in Singapore's offshore and marine sector.

Elsewhere, Asian equities mostly nudged higher on Tuesday as positive signs emerged on trade talks, and ahead of earnings from some of the world's largest conglomerates. 

Japanese markets are closed today for the Imperial Enthronement Day, as Emperor Naruhito's enthronement ceremony will take place, almost six months after he ascended to the throne. 

South Korea's Kospi added 1.2 per cent, while Australian stocks also gained 0.4 per cent. Hong Kong's Hang Seng rose 0.2 per cent at the break, and China's Shanghai Composite was little changed. 

Jeffrey Halley, senior market analyst at Oanda noted that the US earnings season is now in full swing, and with the exception of Boeing, earnings from most industry heavyweights have been "pretty good" thus far. 

"McDonald's results today should be a happy meal, and I would expect Microsoft and Amazons results tomorrow to provide a nice upsize," added Mr Halley. 

In a research note on Tuesday, UOB noted that the Asia data docket is light today, with market attention on Malaysia's foreign reserves, Taiwan unemployment rate and Hong Kong inflation data. 

"In the US, the Richmond Fed manufacturing index for October and September's existing home sales will be due. Otherwise, Brexit remains the key focus," the UOB analysts said.
