UPDATE 1-European shares flat, take a breather after global rally

* STOXX up 0.1 pct

* Rise in the euro pressures exporters

* Investors await Hammond's UK budget

* Utilities lead gainers (Adds more stocks, quotes)

LONDON, Nov 22 (Reuters) - European shares traded only slightly higher on Wednesday, losing some of the momentum that pushed stocks in Asia and on Wall Street to new highs overnight on continued faith in synchronised global economic growth.

The STOXX 600 benchmark was up 0.1 by 1023 GMT with European bourses trading sideways as a 0.1 percent rise in the euro put pressure on exporters, notably on the constituents of Germany's DAX, which shed 0.2 percent.

"I see very few people repositioning themselves on the markets before a period of low liquidity like Thanksgiving," said Pierre Martin, a senior trader at Saxo Bank.

He argued that many investors had taken advantage of last week's dip to take new positions on stocks but that in the absence of major economic or corporate news, there was currently little incentive for them to aggressively seek new opportunities.

Norwegian media group Schibsted posted the sharpest decline of the index after an offering of B-shares to finance mergers and acquisitions in online classifieds. Its shares retreated 7.1 percent

Utilities posted the best sectoral performance in Europe, with Germany's RWE and Spain's Endesa leading the pack with rises of 3 percent and 2 percent respectively.

UBS upgraded RWE to "buy", saying coal and carbon risks may have been overestimated, while Moody's raised its forecasts for French power pricing, reflecting a rebound in commodity prices.

Akzo Nobel rose 1.1 percent after it called off a merger of equals with U.S. coatings company Axalta.

The FTSE was up 0.3 percent, about two hours before British finance minister Philip Hammond was due to present his budget, under pressure to help unhappy voters as the country faces faltering economic growth.

While some traders said they were not holding their breath for any major announcement, given the government's limited room for manoeuvre, others were on the lookout for initiatives that could impact UK housebuilders.
