LME zinc looks technically firmer with US dollar weakness, general commodity strength and short covering by commodity trade advisory players providing support, a London broker says. "If the market can hold above $3,700 a metric ton then $4,000/ton is only a short step away," he adds. Zinc's fundamentals aren't as bullish, however, but notes momentum from the rest of the base metals complex and "lurking stops on the way to $4,000/ton could be enough." LME zinc last at $3,710/ton, +6% from Tuesday's low.
