Since stocks and commodities seem to take their cues from the U.S. dollar, many traders are trying to determine if the greenback’s rally is simply a technical bounce or a sign that investors are shunning risk.

PowerShares DB US Dollar Bullish (NYSEArca: UUP) was rising again Friday as oil and U.S. stocks dropped. The exchange traded fund, which follows the dollar’s movements against a basket of currencies, is on track for a gain of about 2% this week.

Meanwhile, CurrencyShares Euro Trust (NYSEArca: FXE) has been hit by fresh concerns over the sovereign-debt issues in Europe’s periphery.

The dollar ETF found support just over a week ago, followed by the recent oversold bounce, says Tarquin Coe, technical analyst at Investors Intelligence.

However, the analyst suggests a trade that would profit from the dollar resuming its downtrend.
