NEW YORK, Jan 25 (Reuters) - Wall Street's recovery rally faltered on Friday as stocks pulled back from early gains on renewed fears that Washington's fiscal stimulus package for the U.S. economy will not be a panacea for the credit-stressed global financial system.
Other markets buoyed on Thursday by revived economic optimism, including the dollar and commodities, also cut early gains.
Shares retreated from a buoyant early start in New York, damping Europe's earlier gains, as the warm glow the U.S. economic package that emerged on Thursday and a strong earnings report early in the day from Microsoft Corp <MSFT.O> gave way to uncertainty.
In volatile global equity markets, investors once again began fretting over fears of more surprises lurking in the troubled financial sector, amid efforts by U.S. officials this week to bolster the weakened bond insurance business.
Investors have worried that the declining fortunes of bond insurers could cause deeper financial losses on top of last year's mortgage debacle and deal a further blow to beaten down stocks and the beleaguered U.S. economy.
This week, rattled investors have had to contend with recession fears that have pummeled world stocks, though many took comfort from the fact that some of the worst falls were the anomalous result of a rogue trader in France, not the sign of systemic meltdown.
This topsy-turvy ride, which included a sharp two-day rally on Wednesday and Thursday, left nerves frayed, inspiring a round of nervous profit-taking in equities.
"The extreme optimism of the past two days was a bit misplaced," said Michael James, senior trader at regional investment bank Wedbush Morgan in Los Angeles. "The economic backdrop hasn't changed and there is still a high level of nervousness about any headlines that reinforce there is still reason to be concerned about the market's direction."

The wild ride in stocks left some investors seeking a safe-haven in government bonds, pushing U.S. Treasury debt prices higher and, therefore, yields lower.
