"The number is disappointing and moderately concerning, but one month does not make a trend," David Roda, the Miami- based regional chief investment officer for Wells Fargo Private Bank, said in a phone interview. His firm manages $170 billion. "Yes, it's a miss and it's worth focusing on, but we don't think it changes our forecast for a modest im
provement in employment this year. It's a good day to buy stocks because it made the markets nervous."
Payrolls grew by 88,000 workers last month, the smallest in nine months, after a revised 268,000 gain in February that was higher than first estimated, Labor Department figures showed Friday in Washington.

Increased stimulus may bolster a global economy forecast by the World Bank in January to expand 2.4 percent this year, down from a previous projection of 3 percent.

"This is unprecedented on many levels," said Pippa Malmgren, president and founder of Principalis Asset Management in London and a former financial-market adviser to President George W. Bush. "Not only do you have the most in terms of size of economy or number of central banks, but the effort is a record effort. We've never seen such unconventional methods used to create as much inflation as possible."
