For 25 years, Steven Halpern, editor of TheStockAdvisors.com, has surveyed the leading financial newsletter advisors asking for their favorite stocks for the coming year. This article is one of 100+ ideas in the Best Stocks for 2008 report.

In his Forbes ETF Trader, Jim Lowell says his top 2008 speculative bet is PowerShares DB G10 Currency Harvest Fund (ASE: DBV).

"This exchange-traded fund is a unique way to play the bank shot of the wildly volatile currency markets. It seeks investment results that correspond to the price and yield performance of the Deutsche Bank G10 Currency Future Harvest Index.

"This index is intended to take advantage of the fact that currencies associated with high-interest rates tend to rise in value relative with those associated with low-interest rates.

"The ten currencies that the index selects from are the US dollar, the euro, Japanese yen, Canadian dollar, Swiss franc, British pound, Australian dollar, New Zealand dollar, Norwegian krone, and Swedish krona.

"The upshot: interest rates are always rising in one of the above economies while falling in another -- 2008 will be no different."
