THE sharemarket closed higher yesterday, clawing back a large part of Monday's losses, after the central bank cut official interest rates to the lowest since the global financial crisis.
But market observers said the quarter-percentage-point cut to the cash rate had only a modest effect and investors still appeared to lack commitment.

The S&P/ASX 200 Index finished 58.7 points, or 1.5 per cent, higher at 4043.7.
CMC markets chief market strategist Michael McCarthy said currency markets expected a cut of 50 basis points and equity markets had priced in no cut, so the dollar and the sharemarket both rose.
"What's reflected here is the pre-positioning of the market," Mr McCarthy said. "Given the massive [recent] falls we've seen in both currency and sharemarkets, it's difficult to imagine that there are people waiting on the sideline to pull the 'sell' trigger. If they wanted to sell, they would have already done so.
"So what we're left with is a buying reaction in both markets. But this a lot more to do with the positioning going into it rather than any actual read of the figures."
In the near term, the market would be affected by the debt crisis in the eurozone, the strength of the US and Chinese economies, and speculation on this month's Greek election, he said.
