NEW YORK (CNNMoney) -- U.S. stocks rose Wednesday, but closed off the highs of the day, on a combination of improved economic data and easing concerns about Europe's debt crisis.

The Dow Jones industrial average (INDU) rose 83 points, or 0.6%, to end at 12,716. The S&P 500 (SPX) gained 12 points, or 0.9%, to 1,324. The Nasdaq rose 34 points, or 1.2%, to 2,848.

Wednesday's advance extends last month's strong gains. It was the best January for the S&P and Dow since 1997 and since 2001 for the Nasdaq.

Financial stocks were among the best performers, with shares of Citigroup (C, Fortune 500), Morgan Stanley (MS, Fortune 500) and Goldman Sachs (GS, Fortune 500) up between 2% and 4%.

Traders said bank stocks were supported by expectations that a highly anticipated IPO filing by Facebook could signal a rebound in capital markets activity.

Meanwhile, the technology sector was supported by strong quarterly results from chipmaker Broadcom and data storage company Seagate.

A key index of U.S. manufacturing activity came in slightly below expectations, but still signaled expansion in the sector. Earlier reports showed manufacturing activity picked up in China, Germany, France and the United Kingdom.

"Reports out of China and the U.S. today are clearly more positive," said Art Hogan, managing director at Lazard Capital Markets. "The economic data today is one of the biggest drivers."

Meanwhile, investors welcomed signs that talks in Greece are progressing on a second bailout and a write down of the nation's private-sector debt load. In the bond market, yields on Portuguese government bonds eased after the nation drew strong demand for an auction of short-term bills.

"As long as Europe doesn't implode, it seems like the market wants to go higher," said David Rovelli, managing director of U.S. equity trading at Canaccord Adams.

The other big news Wednesday looks likely to be Facebook's long-awaited IPO filing. According to reports from outlets including the New York Times and CNBC, Facebook is seeking to raise up to $5 billion in its offering.

If that number is correct, Facebook would by far be the largest global IPO by an Internet-focused company, according to data from Dealogic. Some experts have suggested that the social network could be valued between $75 billion and $100 billion once it starts trading, which will likely happen a few months after its initial filing.

Pfizer (PFE, Fortune 500) is recalling 1 million packs of birth control pills, after the pharmaceutical giant discovered that some blister packs may contain an inexact count of inert or active ingredient tablets, and that the tablets may be out of sequence.
