LONDON, April 20 (Reuters) - European shares hit a one-week closing high on Wednesday as strong earnings boosted auto and tech shares, with analysts saying stocks were set to post more gains on attractive valuations and improving economic picture.
A sharp fall in the Euro STOXX 50 volatility index <.V2TX>, Europe's main barometer of anxiety, to a 40-month low signalled risk appetite had improved, but experts said the euro zone debt crisis stayed in the background and could limit gains.
Greek shares <
> fell 2.6 percent, while the country's banking stocks <.FTATBNK> slipped 4.6 percent, with traders citing market talk that a debt restructuring could be imminent.A strong majority of economists polled by Reuters said Greece will have to restructure its debt in the next two years. Greek and Portuguese bond yields have hit new highs in recent sessions. [
]But the broader market stayed strong, with the FTSEurofirst 300 <
> index of top European shares ending 1.9 percent firmer at 1,137.81 points, the highest close since April 11 and the biggest one-day percentage gain in nearly five months."The underlying economic cycle is still conducive to corporate earnings growth and the results season is showing that up," said Ian Richards, European equity strategist at RBS.
"For now, investors want to focus on that central scenario of robust global growth, further corporate earnings progression, cheap valuations and the asset allocation story." According to Thomson Reuters Datastream, Europe's STOXX 600 index <
> trades at 10.7 times one-year forecast earnings, below a 10-year average of 13.6.Automobile shares topped the gainers' list, with PSA Peugeot Citroen <PEUP.PA> jumping 4.7 percent after quarterly revenue beat forecasts. The STOXX Europe 600 Automobiles & Parts <.SXAP> index rose 4 percent, while Fiat <FIA.MI> climbed 4.6 percent after saying it had cut its debts. [
]Technology stocks were also in demand, with forecast-beating revenue from U.S. bellwether Intel <INTC.O> boosting chipmakers. The European tech sector index <.SX8P> rose 2.7 percent, ASML <ASML.AS> advanced 5.3 percent and ARM Holdings <ARM.L> was up 5.7 percent. [
]"There is a push and pull between fear and the positive earnings that companies are delivering. Long-term we are bullish on Europe, we think there are a lot of positive opportunities," said Randeep Grewal, director of European equities at F&C Asset Management, which manages 105 billion pounds ($171.6 billion).

EARNINGS OUTLOOK
Strong earnings have underpinned the market. According to Thomson Reuters StarMine, 83 percent of the 70 S&P 500 <.SPX> companies that have reported first-quarter results have either beaten or met expectations.
Some fund managers stayed cautious on the stock market's outlook, but ruled out any sharp decline in share prices.
"The largest part of recovery in earnings since 2009 is behind us and progress, although positive, will be less easy from here," said Don Fitzgerald, fund manager of European equities at Tocqueville Finance, which manages $2.2 billion.
"There are valid concerns regarding sustainability of margins, commodity price pressures, government finances and the start of the tightening cycle. Nevertheless, interest rates remain very low worldwide, particularly in the U.S., and valuations are not yet stretched. So a severe market correction is not likely."
Fredrik Nerbrand, global head of asset allocation at HSBC, said equities looked relatively cheap versus credit, but were highly exposed to earnings downgrades.
"Sell-side analysts are still looking for significant improvements in margins and I don't like that," he said, citing a potential margin squeeze from high oil prices, rising wages in Asia and waning productivity gains. All of which pointed to a contraction of forward-looking margin assumptions, he added. (Additional reporting by Simon Jessop and Joanne Frearson; Editing by David Holmes)
