* FTSEurofirst 300 up 0.5 pct, Euro STOXX 50 down 0.4 pct

PARIS, Jan 3 A leading pan-European share index ended higher on Thursday, helped by rallying Swiss blue-chips returning from a national holiday and by forecast-beating U.S. private-sector jobs figures ahead of key payrolls data.
Switzerland's SMI benchmark surged 2.9 percent, catching up with the European market rally on Wednesday sparked by Washington's deal to avoid the so-called fiscal cliff, with UBS up 4.1 percent and Roche up 3 percent.
The FTSEurofirst 300 index of top European shares ended 0.5 percent higher at 1,162.56 points, its highest closing level in nearly two years.
The euro zone's blue chip Euro STOXX 50 index, however, lost 0.4 percent, to 2,701.22 points, with Germany's DAX down 0.3 percent, France's CAC 40 down 0.3 percent and Spain's IBEX down 0.5 percent.
Euro zone stocks trimmed their losses after better-than-expected private-sector jobs data - a day before all-important payrolls figures for December - but the data failed to spark a sustained broad-market rally.
"It means that people remain sceptical about tomorrow's payrolls," Saxo Banque senior sales trader Alexandre Baradez said.
"It basically means two scenarios: a strong figure and indexes hit new highs, or a sluggish figure which would trigger a pull-back. A lot of investors are looking for a reason to book profits."
Baradez said the drop in the euro currency, down 0.6 percent at $1.3108 against the dollar on Thursday, could signal an imminent pull-back in European equities as the single currency usually moves first.
The 30-day rolling correlation between the euro and the Euro STOXX 50 index, which has been around 0.45 for most of December, sharply dropped to 0.2 this week, the weakest correlation between the two assets in 18 months.
The ADP National Employment Report showed on Thursday the private sector added 215,000 jobs last month after increasing their payrolls by 148,000 in November. The broader U.S. non-farm payrolls data, due on Friday, is expected to show employers added 150,000 jobs last month.
Swiss watch makers Richemont and Swatch surged 5.7 percent and 6.4 percent respectively, outpacing the SMI, boosted by strong watch sales figures from Hong Kong for November.
"The double-digit performance gives investors confidence to believe in a better level of activity in Asia Pacific in 2013 versus 2012," a Paris-based trader said.
"It confirms the now well-accepted fact that the third quarter seems to have been a trough in sales growth in 2012."
Telecom gear maker Alcatel Lucent surged 10 percent as a recommendation upgrade from Credit Suisse sparked interest in the stock and prompted short sellers to further cut their negative bets.
Hedge funds have been slashing their short-selling positions on the stock in the past few weeks, Markit data showed. About 9 percent of Alcatel's shares are out on loan, down from a peak of 17 percent in mid-November.
