In his Commodity Trend Alert, Eric Roseman believes a short-term correction is "highly likely." But the resource expert still considers ASA Limited (NYSE: ASA) a "terrific bargain."

He explains, "For value investors, a great buying opportunity in commodities looms this fall. The fundamentals for commodities remain extremely bullish as we progress into 2008. A weaker U.S. dollar, lower interest rates, and supply deficits across a spectrum of raw materials promises to snowball into another formidable rally for commodities."

However, he cautions, this buying opportunity will come after a "period of digestion." He observes, "Commodities indices have come a long way over the last two months following the mid-August market low. Heavy investor speculation in many raw materials -- namely oil, gold, and wheat -- implies a short-term correction is highly likely."

The advisor notes, "Banks, hedge funds, individual investors, and sovereign wealth funds are all on the same side of the dollar bear market ship; historically, too many bears on the same side of a trade means someone will lose their shirt -- and soon."

Again, he emphasizes that the long-term trend for the dollar is "very bearish." He contends, "The dollar has been going down since it broke from gold in 1971. I don't see a structural change in the dollar's direction, but a cyclical short-term rally is possible following six years of relentless selling."

He notes that his strategy has been to sit on the sidelines over the last few weeks, selectively "cherry-picking our investment themes." For example, he says, "For those who have no current mining exposure, I've placed ASA Limited back on the Best Buys list."

He explains, "Though I'm cautious about a short-term pullback at these levels, ASA Limited is the cheapest way to ride the bull market. This closed-end fund trades at a fat 13.6% discount to net asset value, meaning an investor gets to buy $1 worth of great global gold mining stocks for just $0.86 cents -- a terrific bargain."
