that invest in currencies, commodities and international securities dominate our list of newly rated ETFs.

Among the 24 recently added

ETFs

, seven are currency funds, one of which -- the

(URR) - Get Report

-- is leveraged. Another six buy commodities, including the leveraged

PowerShares DB Commodity Double Long

. Seven more invest internationally, including five "global" ETFs that hold securities from the U.S. and abroad.

Despite the diversity of the newly rated offerings, only two have gained in value during the first five months of this year and in the previous 12 months. The
