MADRID (MarketWatch) -- European stocks were clinging to gains on Monday, supported by advances for banks such as UBS AG after regulators eased a Basel leverage-ratio rule, and after a positive session for Asian markets. Shares of Suedzucker AG jumped after backing its full-year outlook.

The Stoxx Europe 600 index rose 0.1% to 330.28, after closing up 0.5% on Friday to 329.95, a new 52-week high. The index remains at the highest levels since spring 2008.

The Basel Committee on Banking Supervision watered down a leverage-ratio rule for banks on Sunday. Regulators said they had revised the definition of its leverage ratio that will enable banks to report lower levels of overall risks. The move will ease pressure on banks to shed assets or raise more capital to meet that requirement.

Banking heavyweight UBS (UBS) rose 2.8%. Banco Santander SA (SAN)(SAN) gained 1% and BBVA SA (BBVA) added 2.3%. BNP Paribas SA was 0.9% higher. Separately, UBS Chief Executive Officer Sergio Ermotti told Bloomberg Television on Monday that the lender does not plan to spin off its investment-banking unit to meet regulators' demands over holding more capital.

Shares of Suedzucker AG jumped 6.5% after the sugar producer said sales and profit in the fiscal year fell, but backed its fiscal-year outlook.

Markets remain undecided about what Friday's disappointing U.S. jobs data, which saw just 74,000 created in December, means for the Federal Reserve's tapering plans for its bond-buying program. For now, though, Europe was shaking off that news. Patrick Latchford, chief executive at Monex Capital Markets, said in a note that it may take markets a bit of time to digest the jobs news.

"Critically it's going to be about whether this number can be written off as erroneous or if it does indeed point to some bigger underlying weaknesses that are now emerging, although anything that keeps global borrowing rates in check can only be good news for stocks," said Latchford.

Asian stocks ended higher, while U.S. stock futures leaned south. Wall Street finished mostly higher on Friday, shaking off earlier losses in the session from the jobs data, while this week will see earnings from big banks rolling into the spotlight.

The French CAC 40 index rose 0.2% to 4,258.76, helped by banks, with Societe Generale SA up 1.7% and Alcatel-Lucent SA up 3.9%, rebounding from some losses last week. On the downside, shares of Sanofi SA (SNY) fell 1.6%. The company said Monday that it will buy a 12% stake in Alnylam Pharmaceuticals Inc. (ALNY) for $700 million to strengthen its new drug pipeline. The two firms will extend research collaboration to develop and sell new drugs aimed at treating rare genetic disorders.

Away from the main index, shares of Peugeot SA rose 5.6%.

The German DAX 30 index gained 0.3% to 5421.75. Shares of Continental AG lifted 2.7% after the auto-parts maker said it sees further growth after a rise in 2013 sales.

Other gainers in Europe included Debenhams PLC up around 5% after Sports Direct said it had purchased 4.6% of the retailer. On the main index, other retailers were also gaining. Shares of Wm Morrison Supermarkets PLC jumped 3.4%, and J. Sainsbury PLC added 0.8%.

The FTSE 100 index rose 0.2% to 6.751.36.
