As Federal Reserve Chairman Ben Bernanke signals that short-term interest rates are going down in the U.S., activity in exchange-traded funds linked to different currencies around the world are spiking.

And that's bringing both short-term speculators as well as long-term ETF investors into the market. The combination of more economists forecasting a prolonged weakening in the greenback and record-high price gains are providing both fundamental and technical analysts with a field day.

The result is something akin to a perfect storm in drawing attention to a rather new form of ETF investing, says Joe Baker, a longtime advisor at Alcus Financial Group in Mt. Pleasant, S.C.

"I've never seen this much interest in currency ETFs before," he said with a laugh. "There's just a pile of money coming into these funds now."

Take the Rydex CurrencyShares Euro Trust (NYSE: FXE). In the past 12 months, FXE's price has jumped 14.5%. Along with that rise, its average daily volume has risen from around 100,000 shares in early September 2007 to more than 400,000 shares now.

"We've got the Fed chairman this week essentially telegraphing to the market that rates are coming down," said Jerry Slusiewicz, president of Pacific Financial Planners in Newport Beach, Calif. "That's driving up prices and sending trading volume up in droves."

He hasn't jumped on the bandwagon yet. Still, Slusiewicz says FXE looks very attractive right now on several different levels. And as midday approached on Thursday, he was inching closer to making a call for some of his clients.

On the technical side, FXE broke what's called a triple-top on price charts. That's a rare occurrence. But since the current run began with the euro in early fall 2007, Slusiewicz says FXE's low point has been about 5.5% of its current high.

"So even if there's a fallback, the short-term downside risk in this current pattern seems pretty attractive at less than 6%," he added.

Slusiewicz uses stop/loss orders with any ETF transactions. For FXE, he's looking at $143.40 per share. "That's the low side of the trading range we've been in since late October of 2007," he said.

Slusiewicz also checks fundamentals before buying an ETF. Those are attractive as well for FXE, he says. With comments made by Bernanke before Congress on Wednesday and Thursday, futures traders are now pricing into the market a 50 basis points rate cut, Slusiewicz says.

That makes the U.S. dollar less attractive globally. "So far, the European Union hasn't cut rates, even though they've talked about it," Slusiewicz said.

Another confirming signal could be that gold keeps soaring since the Fed started cutting short-term rates in September. Slusiewicz also owns StreetTracks Gold Shares (NYSE: GLD). That ETF's price has shot up 45% since early fall.

"So gold traders are expecting the dollar's weakness to continue," said Slusiewicz. "We're seeing a lot of confirming signals coming together right now. And it looks like this could be a long-term trend."

Bruce Zaro, a strategist at Delta Global Advisors Inc., says he's seeing a lot of interest in currency ETFs lately from traders and long-term oriented investors.

"From a technical standpoint, this looks like a good buy for traders," he said. "And given that FXE's dividend yield is around 2.74% right now, which is on par with the broad stock market, that's another real plus."

With Tuesday's breakout, his technical analysis of price charts indicates that FXE could move up to the $160-per-share range later this year. "If that happens, its price appreciation as well as its yield would translate into a gain of 9.33% since Tuesday's breakout," Zaro added.

But currency ETFs are also attractive to long-term investors, he says. "We consider currencies as a separate asset class from stocks and bonds," said Zaro. "They're categorized in our portfolios as true alternative investments."

Currency ETFs as a whole make up about 5% of the firm's long-term-oriented portfolios. Some more aggressive traders prefer to use up to 10% of their total assets in various currency ETFs.

Besides FXE, Zaro also is investing in CurrencyShares Australian Dollar Trust (NYSE: FXA) and CurrencyShares Swiss Franc Trust (NYSE: FXF). Both also have been on a run lately.

"Fundamentally, you can also make a strong argument that the Aussie dollar with its base in natural resources is likely to keep experiencing strong growth," Zaro said. "We also think that the Swiss economy is a fairly stable economy and has sound money policies that should hold up well in the future."

Roger Nusbaum has been investing in currency ETFs since their debut some two years ago. The portfolio manager at Your Source Financial in Phoenix, Ariz., is cutting back in the firm's stake in FXE, though.

He bought FXE last fall at around $141 per share. Nusbaum sold it this week at $149.66 on the current spike. "Similar to oil and other currencies, typically when you see a big move like this, you see speculators coming out of the woodwork," he said.

Nusbaum says over the next few months, FXE could have already peaked. "But we didn't completely give up on the theme of a weaker dollar," he added. "It was more of a trimming."

As the spotlight shines brighter on the euro, he's holding on to two-year notes bought directly in some less-known foreign markets. Those include short-term paper from Norway, Australia and the U.K.  

"We're lightening up a little on the euro," Nusbaum said. "The big picture, though, is that the dollar will probably continue to show weakness. But in the short run, it's plausible that the U.S. dollar will have a snap-back rally."

Investors without exposure to currencies need to balance current conditions with longer-term objectives, he says. "Trading on short-term movements in currency is not something I'd suggest," Nusbaum said. "We've been in them for a relatively long time now. I'm just trying to protect those profits."

But for someone with no exposure to currencies and considering adding this asset class to their long-term asset allocation plan, he advises taking a slow-but-steady approach. "At this point in the run-up in foreign currencies, it might be better to wade into the market now," Nusbaum said. "If your allocation calls for 5% in currencies, perhaps start by investing 2% of that now."

He tells financial advisors working for the firm that currency ETFs should be viewed as a different sort of investment than stocks or most fixed-income funds.

"If you're going very short in bonds, there's probably not a lot of difference between owning bonds and currency ETFs," Nusbaum said. "But if you're buying something because it looks like interest rates are going up, then currency ETFs provide you with more of a chance to directly benefit from that movement."
