Federal Reserve chairman Alan Greenspan annoyed the bears by stating that America's first recession in a decade appears to be over. Helping the bullish cause, too, was further evidence that the US economic recovery is gathering pace. Non-farm labour productivity increased at a revised 5.2% annual rate in the fourth quarter, from an initial estimate of 3.5%. Jobless claims in the US dipped 5,000 to 376,000 in the week ended 3 March, compared with a forecast 2,000 increase.
