THE sharemarket closed flat despite a sell-off triggered by disappointing trade balance numbers. The benchmark S&P/ASX200 index closed down 3.1 points, or 0.07 per cent, at 4333.9 points while the broader All Ordinaries index eased 5.5 points, or 0.12 per cent, to 4418.9.
Options Xpress analyst Ben Le Brun said the bourse was resilient in afternoon trade following figures on Australia's trade deficit, which had narrowed, but not as much as hoped.
The trade deficit fell to $480 million in February, from $971 million in January.
"There was obviously a knee-jerk reaction to the international trades and goods and services data," Mr Le Brun said. "We've seen the Aussie dollar fall, which has supported some ends of the market. Certainly, the healthcare sector has been one of the best performers."
ResMed was up 2.67 per cent at $3.08, Ramsay Health Care gained 2.54 per cent to $19.77, Primary Health Care put on 2.52 per cent to $2.85, Cochlear rose 1.62 per cent to $62.55 and CSL appreciated 1.49 per cent to $36.
Mr Le Brun said a continuation of soft economic data could prompt the Reserve Bank to cut interest rates in May, having kept them on hold this week.
He said insurer QBE had held up the financial sector, rising 47?, or 3.38 per cent, to $14.37.
