The U.S. dollar has been a star performer in recent months, so much so that Wall Street is already abuzz about the adverse impact the stronger greenback is going to have on third-quarter earnings reports, which will soon be trickling in.

While the strong dollar is seen as crimping some exchange traded funds, particularly those offering exposure to dollar-sensitive sectors, such as the Energy Select Sector SPDR (NYSEArca: XLE) and the Industrial Select Sector SPDR (NYSEArca: XLI), some ETFs have been loving life with a rallying greenback.

Even with Monday’s 1.1% decline, the PowerShares DB U.S. Dollar Index Bullish Fund (NYSEArca: UUP) is up 7.4% since the start of the third quarter. UUP is the most recognizable dollar ETF due in part to the fact that is the ETF proxy for the U.S. Dollar Index. The U.S. Dollar Index tracks the price movement of the U.S. dollar against a basket of currencies, including the euro, Japanese yen, British pound, Canadian dollar, Swedish krona and Swiss franc.

The WisdomTree Bloomberg U.S. Dollar Bullish Fund (NYSEArca: USDU) is also coming of age as the dollar finds firmer footing. USDU, which debuted in December 2013, is showing investors there are advantages to active management with currency funds.

USDU is well positioned to benefit from diverging developed market monetary policies, particularly at the top of the ETF’s lineup. The Eurozone and Japan, home to central banks that have overtly signaled commitments to lower interest rates and weaker currencies, combine for 50.4% of USDU’s weight.

New Zealand, the one developed market that has raised rates this year, is not found among USDU’s 10 country exposures, but the fund does have a 6.2% weight to Australia. While the Reserve Bank of Australia has recently paused its rate-cutting scheme, rates there are at record lows and RBA continues to view the Aussie as overvalued. [Embracing Australia ETFs]
