NEW YORK, April 30 (Reuters) - COMEX June gold futures jumped to a 6-week peak at midday Wednesday after broad-based buying lifted futures above technical resistance, following the euro's surge to four-year highs against the U.S. dollar, floor sources said.
June gold futures on the New York Mercantile Exchange's COMEX division at 1255 EDT traded at $339.70 an ounce, up $5.70 and at a peak since March 19, after breaking above near-term resistance at $339.40. Its session range was $334.00 to $340.00.
"It looks like a combination of fund and trade buying in the market, and some short-covering too," said one COMEX floor broker.
Investors piled into attractive euro zone yields at the expense of the dollar after it failed to capitalize on a rise Tuesday in April consumer confidence and two days of gains on Wall Street.
