LONDON (MarketWatch)--European stock markets rose sharply Monday, as investors welcomed signs of progress in U.S. debt negotiations after top politicians appeared optimistic over prospects for a deal to avert the so-called fiscal cliff.

The Stoxx Europe 600 index jumped 2.2% to close at 268.58, marking the best daily performance since Sept. 6--the day European Central Bank President Mario Draghi unveiled details of an unlimited bond-buying program.

"We have had a significant number of weak days and the markets were quite oversold. There is a perception that progress has been made in fiscal-cliff negotiations," said Neil Wilkinson, senior fund manager at Royal London Asset Management.

"The U.S. market was very strong [Friday], and we're playing catch-up in Europe," he said.

Among notable movers in the index, shares of Nokia Corp. (NOK) surged 9% on reports that supplies of the Lumia 920, the handset maker's flagship smartphone, have sold out in Germany.

Shares of Barclays PLC (BCS) jumped 6.6%, as Goldman Sachs lifted its rating on the U.K. bank to buy from neutral.

However, Fugro NV shares tanked 14%, after the firm said late Friday that Arnold Steenbakker will step down as chairman of the board of management due to a difference of opinion.

Outside the main benchmark index, shares of SAS AB soared 23%, after most of the Scandinavian airline's employees accepted its major cost-savings plan.

Debt in Greece

Greece remained in the spotlight as the Eurogroup of euro-zone finance ministers prepared to meet for the second time in two weeks to discuss the release of a long-delayed tranche of bailout money and future debt sustainability.

After a meeting last week, Eurogroup chair Jean-Claude Juncker and International Monetary Fund chief Christine Lagarde clashed over how to reduce Greece's growing debt pile, with Lagarde arguing against the euro zone's call to give Greece two additional years--until 2022--to cut its debt load to 120% of gross domestic product.

"The euro zone really needs to stop tiptoeing around the issue. The question is: 'Do we want to keep Greece inside the euro tent?' " said Stephen Pope, managing partner at Spotlight Ideas, in a note.

"If the answer is yes, the leaders have to get a hard-core number on what that will cost--clearly another deep if not total write-down of Greek outstanding debt. If that price is too high to pay--do the right thing, cut Greece off," he said.

Fiscal-cliff talks

Investors also looked to the U.S., where signs indicated policy makers might be getting closer to an agreement to avoid hundreds of billions in automatic spending cuts and tax hikes slated to take effect Jan. 1, referred to as the fiscal cliff.

During an overseas trip to Asia, President Barack Obama said Sunday he's confident "we can get our fiscal situation dealt with." Separately, House Minority Leader Nancy Pelosi said any deal must include tax-rate hikes for the wealthy.

Republicans, meanwhile, expressed some willingness to consider new revenue, but they didn't endorse changes in tax rates for the rich. .

Concerns that Democrats and Republicans would fail to make a deal in time hamstrung European investors last week, sending the Stoxx Europe 600 to its lowest level since early August.

Wall Street benchmarks, however, closed higher on Friday, after both sides viewed the opening round of negotiations as constructive. And U.S. stocks rallied out of the box Monday.

Monday movers

Risk-sensitive sectors such as banking and resource shares ranked among Monday's major gainers in Europe.
