THE sharemarket closed lower yesterday, with investor caution about this weekend's Greek elections overriding positive offshore leads.
At the close, the benchmark S&P/ASX 200 Index was down 9.1 points, or 0.2 per cent, at 4063.8.
The market opened higher but quickly took a U-turn and traded lower for the rest of the day.
CMC Markets sales trader Miguel Audencial said that investors closing out long positions in case of a leftist Greek victory were balanced by others with short positions second-guessing that there might be relief for risk assets.
"The reasons for the rally in the US overnight were not based on economic fundamentals, they were based on speculation about further stimulus from the US," Mr Audencial said.
"That's not really a good foundation if you want to start a rally, that's why the selloff was quite quick."
In local economic news, the Westpac-Melbourne Institute Survey of Consumer Sentiment showed a rise for June of 0.3 per cent at 95.6 index points.
