The strides in equities were a sign of just how browbeaten investors had been in a year that saw the worst performance since the 1930s, and came despite news of a worldwide contraction in the manufacturing sector.

Investors seemed to set aside the bad news, pushing the Dow Jones industrial average <.DJI> up a whopping 258 points, or 2.94 percent. The FTSE Eurofirst jumped 2.98 percent, with traders evidently hoping that with 2008 so bad, 2009 could only be better.

"We're seeing some New Year optimism," said Andre Bakhos, president of Princeton Financial Group, in Princeton, New Jersey. Global stocks as measured by the MSCI world index <.MIWD00000PUS> were up 2 percent.

Yet the economic backdrop was hardly comforting. Factories in China, India and Eastern Europe joined the United States and other developed countries in slashing output and jobs in December, another sign recession is spreading to emerging markets.

U.S. manufacturers had their worst December since 1980, and new orders fell to a record low, according to the Institute for Supply Management. The downturn was even more severe than already pessimistic economist forecasts.

In Europe, the industry group's index hit a record low. This pointed to a deepening recession on the continent and sent investors back into dollars and out of the euro.

"It casts an even darker shadow over the state of the euro zone economy," said Bank of America economist Gilles Moec.

"We think it is consistent with a major contraction in GDP both in the fourth quarter of 2008 and the first quarter of 2009 -- probably something like a contraction of a full percentage point in both quarters."

The euro was down 1 percent against the dollar at $1.3854.

Given weakness in the economy, analysts expect any stimulus package that emerges from President-elect Barack Obama's administration to be quite large -- perhaps as big as $1 trillion. Still, few expect the benefits to be immediate. At best, the government's efforts will prevent a deeper downturn, economists say.

While the going was good for stocks, U.S. Treasury debt prices dipped in a sign investors' aversion to risk was easing a bit after a year in which $14 trillion was wiped off world stock markets.

Benchmark 10-year notes were down 1-25/32 and yielding 2.41 percent, up 19 basis points from Wednesday but still not too far above a 50-year low of 2.04 percent set in December.

The oil markets, meanwhile, were back on the upswing, powered by the conflict between Israelis and Palestinians and Russia's vow to cut off gas supplies to neighboring Ukraine.

A barrel of crude oil was trading up $1.41 at $46.04. Oil prices fell 54 percent as a whole in 2008, from $95.98 to $44.60 a barrel at the close on December 31, with the spike to $147.27 set on July 11 in between. As demand dissolved in the wake of the global recession, prices were hammered in the closing months of the year.
