PARIS, March 31 (Reuters) - European stocks fell nearly 2 percent early on Monday, heading for their third consecutive quarter of losses, with Swiss bank UBS <UBSN.VX> tumbling on renewed worries over the prospect of more asset writedowns.
Vodafone <VOD.L> was the biggest faller among Europe's blue chips, down 5 percent after Morgan Stanley cut its recommendation to "underweight" from "overweight" and slashed its price target to 170 pence from 215p, citing concerns over potential EU regulatory action to align mobile phone termination rates with costs.
At 0850 GMT, the FTSEurofirst 300 <
> index of top European shares was down 1.6 percent at 1,245.36 points, after falling by as much as nearly 2 percent.The index is on track to end the quarter with a loss of about 18 percent -- its worst quarterly performance since the third quarter of 2002.
"This subprime crisis isn't over yet and we might see more writedowns from banks when they report their first-quarter results, and that obviously is entangling stock markets," said Franz Wenzel, strategist at AXA Investment Managers, in Paris.
UBS shares fell 3.8 percent after Merrill Lynch said it expected the Swiss lender to make a further $11 billion of first-quarter writedowns, resulting in a loss of 8.2 billion Swiss franc ($8.22 billion) in the first three months.
"We estimate that UBS' capital base can withstand $16 billion of further writedowns on legacy assets and we expect $11 billion of that capacity to be absorbed in Q1," Merrill Lynch said in a note. "Based on our conservative writedown forecasts, UBS will possibly need to raise capital this year to cover its legacy writedowns."
Other banks were on the downside on Monday, with BNP Paribas <BNPP.PA> down 1.9 percent and Credit Suisse <CSGN.VX> down 2.9 percent.
The DJ Stoxx bank index <.SX7P>, down 1.9 percent on the day, has lost nearly 20 percent since the start of the year as investors fear that banks have not yet revealed the full impact of the global credit crisis on their books.
Investors were eagerly expecting a proposal due later on Monday from U.S. Treasury Secretary Henry Paulson for broad reform of U.S. financial market regulation.
EARNINGS OUTLOOK
Stock markets around the world have fallen over the past few months on worries about the turmoil in the U.S. subprime mortgage market as well as over the prospect of a U.S. economic downturn, and a number of strategists said forecasts for corporate earnings will have to be trimmed.
"A lot of people are calling for earnings growth between 5 and 15 percent depending on the region, but we think that actually, we might see an earnings recession this year. So there is some denial," Wenzel said.
