THE sharemarket finished stronger yesterday, boosted by the resource sector, with iron ore players Fortescue Metals Group and Atlas Iron the standouts.
At the close, the benchmark S&P/ASX 200 Index was up 14.6 points, or 0.34 per cent, at 4290.8.
After a strong start, the market eased from its intraday highs to below the key technical level of 4300 points on the S&P/ASX 200, RBS Morgans private client adviser Craig Walker said.
"That 4300-level is a key ceiling, and if the market can close above it, that would attract a few investors into the market," he said.
A production fault on a railway at a mine owned by Brazil's Vale boosted local iron ore stocks, Mr Walker said.
"There was an issue that may affect the short-term supply of iron ore," he said. "That followed weakness on Friday due to potential cyclone activity in the west, and Fortescue and Atlas have made considerable gains."
Fortescue Metals Group surged 17?, or 2.9 per cent, to $5.98, while Atlas Iron jumped 11?, or 3.8 per cent, to $3.04. BHP Billiton gained 38?, or 1.1 per cent, to $35.35, and Rio Tinto advanced 73?, or 1.1 per cent, to $65.85.
