"The path of least resistance for the market remains higher, and despite some mixed economic data, investors are concluding that stocks remain a better place to be than risk-free assets," Jim McDonald, chief investment strategist at Chicago-based Northern Trust Global Investments, told Reuters.
Among the mixed US data was last week's unexpectedly poor March payrolls report.
Still, American central bankers remain optimistic about the recovery. The Federal Reserve's policy makers noted "moderate economic growth had resumed following a pause late last year," according to the FOMC's March minutes released today.
Indeed, a continued improvement in the jobs market might signal the easing of the end of the Fed's monthly asset purchases, currently set at US$85 billion.
"If the outlook for labour market conditions improved as anticipated, it would probably be appropriate to slow purchases later in the year and to stop them by year-end," according to the minutes reflecting the opinion of "several" policy makers.
US Treasuries weakened as a result, sending the yield on the current 10-year note four basis points higher to 1.79 per cent and curbing demand for today's auction of the same maturity.
In a speech in New York, IMF chief Christine Lagarde urged global central bankers to keep their feet on easy money policies. "This crisis has been long, bitter, and hard. The priority now is to take advantage of any financial breathing space, and put it to good use. This is such a moment. We cannot afford to let up."
In Europe, the Stoxx 600 Index added 1.8 per cent from the previous close. Benchmark stock indexes in London, Paris and Frankfurt also rallied, rising 1.2 per cent, 2 per cent and 2.3 per cent respectively.
The FTSE 100 has risen 2.2 per cent in the last three days, its best three-day performance since January.
