LONDON, June 16 (Reuters) - European shares edged up in early trade on Wednesday, extending a rally to six days by tracking gains on Wall Street where the S&P 500 <.SPX> lifted above its 200-day moving average.
But the rise was limited as euro zone worries resurfaced, causing the market to trimmed strong gains made in early trade.
At 0850 GMT, the FTSEurofirst 300 <
> index of top European shares was up 0.1 percent at 1,038.26 points, after rising 0.7 percent on Tuesday to its highest close in over a month."The market has got over political, euro and sovereign debt worries, although none of those issues have gone away," said Justin Urquhart Stewart, director at Seven Investment Management. "We have got a bit of calm. The market has gone back to looking at corporate valuations, which are looking good."
Energy companies gained sharply after crude prices <CLc1> closed just below $77 in New York on Tuesday, on economic optimism. Total <TOTF.PA> and Royal Dutch Shell <RDSa.AS> gained 0.9 percent and 1 percent respectively.
BP <BP.L>, facing a bill running into several billion dollars for putting right an oil spill in the Gulf of Mexico, dipped 0.5 percent after closing at a 13-year low on Tuesday.
The heavyweight banking sector was mostly higher, with Royal Bank of Scotland <RBS.L>, Standard Chartered <STAN.L> and Barclays <BARC.L> up between 1 percent and 1.7 percent.
The pan-European index has gained nearly 6 percent in the past six sessions, but is still dowm more than 6 percent from a peak in mid-April, when worries about the euro zone's debt crisis started to intensify.
The premium that investors demand to hold 10-year Spanish government bonds rather than euro zone benchmark German Bunds hit a euro lifetime high as investors grew nervous about Spain's credit markets.
"After the week-long rally, some stocks look overbought, but overall the market is closely following the euro, which has been slipping over the past hour," a Paris-based trader said.
"Concerns over the Spanish debt issues are still lingering."
The euro -- which has been used to assess investor risk appetite in the current climate of jitters about Europe's debt crisis -- hit a two-week high on Wednesday but lacked the momentum to break nearby resistance.

Schroders <SDR.L> fell 2.3 percent after Citigroup cut its rating for the fund manager to 'sell' from 'buy', in a review of British asset managers.
"We expect retail investors to have 'sat on their hands' during recent market volatility, leading to lower gross sales. Worse still, a short-lived market rally could lead to profit-taking. The longer that volatility continues, the higher the risk of managers seeing net outflows in H2," Citigroup said.
Investors will look at U.S. housing data, due before Wall Street opens.
U.S. stocks jumped on Tuesday with investors motivated by successful debt auctions in Spain, Belgium and Ireland, which lifted some of the gloom over Europe's debt crisis.
The S&P 500 turned positive for the year and rose above its 200-day moving average for the first time in a month, suggesting the recent downtrend may be nearing an end.
