THE sharemarket closed on Wednesday at its highest point in 17 months, but still off the day's highs, as positive leads from overseas boosted the local market.
The benchmark S&P/ASX 200 rose 7.8 points, or 0.2 per cent, to 4583.8, while the broader All Ordinaries was up 10.5 points, or 0.2 per cent, to 4591.8.
"We've seen a bit of up and down from the market, but in general terms it hasn't been doing a huge amount," said CommSec analyst Steven Daghlian.
Among the sectors, health jumped 2 per cent, energy added 1.5 per cent, consumer discretionary rose 0.9 per cent and materials inched up 0.5 per cent. Telecoms and financials bucked the trend, slipping 1.3 and 0.3 per cent respectively.

BHP rose 1 per cent to $35.76 after it said it would sell its interest in the Browse LNG joint venture, while rival Rio Tinto jumped 0.7 per cent to $62.20.
"With the miners, you have to take a step back and compare it to the rest of the market this year - the Aussie market is up about 12 per cent this year, the mining sector's down 1.5 per cent, so the mining sector is still struggling and dragging its heels," said Mr Daghlian.
