MADRID (MarketWatch) -- European stock markets notched some moderate gains on Monday, with Italian stocks rallying on relief that a new government is finally in place.

Investors looking ahead to potential easing from the European Central Bank. Earnings news drove Aberdeen Asset Manager PLC higher and Aker Solutions ASA lower.

The Stoxx Europe 600 index rose 0.4% to 297.17, after closing up 3.7% last week, the biggest percentage gain since Nov. 23. The index has been up two of the past three weeks. A higher opening for U.S. markets also underpinned Europe markets.

Aberdeen Asset Management PLC surged 7% after the fund manager posted a half-year rise in pretax profits and assets under management. Aberdeen lifted its dividend 36% even as it said it remains cautious on its outlook.

On the downside, Aker Solutions ASA shares slumped 22% after the oilfield products and services group warned that earnings would "considerably lag current consensus market estimates," owing to cost overruns.

But away from earnings, analysts said Europe markets have been cautiously gaining on expectations the European Central Bank will cut interest rates later this week. The U.S. Federal Open Market Committee also meets, though economists largely expect no change in policy.

Italy's new government finally getting in place also helped underpin markets Monday. Enrico Letta was sworn in as prime minister on Sunday after a lengthy political deadlock, which brought some sense of relief to markets.

"News from over the weekend that Italian PM Letta has formed a new government has provided confidence to the markets," said Atif Latif, director of trading, equities and derivatives at Guardian Stockbrokers, in emailed comments.

Providing further fuel for the case for lower rates in Europe, data showed economic confidence in the euro zone fell more than expected in April. The European Commission said an index of business and consumer sentiment fell to 88.6 from a revised 90.1 in March.

Latif said markets also paid attention to soft six-state German inflation data ahead of Thursday's ECB rate decision.

"The market has been within a tight range today. Still data dependent but talks on central bank action may be tapered and at the same time concern about continual stagnant growth in the economy and how long this will remain for," he said.

Italian stocks were bid higher on Monday, with the FTSE MIB Italy index were ahead of the pack Monday, with a 2% jump to 16,904.53, led by a 2.6% rise for UniCredit SpA. .

Yields at an Italian bond auction of notes maturing at 2023 earlier in the day dropped to their lowest level since October 2010.

Among other indices, the French CAC 40 index gained 1.4% to 3,862.66, led by a 1% rise for heavyweight Sanofi SA (SNY) and a near-1% rise for BNP Paribas SA .

The German DAX 30 index pushed higher after an earlier slump, gaining 0.7% to 7,866.59.

Analysts at J.P. Morgan Cazenove said the German DAX is unlikely to outperform this year and the focus will shift to peripheral markets, listing such reasons as its big representation of capital goods and auto stocks that are sensitive to bad news on the Chinese economy.

Also, the analysts see continued compression in peripheral bond yields, a strong positive for those equities and that means the shine will come off Germany's safe-haven position.

The FTSE 100 index also perked up, gaining 0.3% to 6,554.58. Heavyweight Reed Elsevier PLC fell 2% after analysts at Citigroup downgraded shares to neutral from buy.
