NEW YORK (TheStreet) -- Not many investors pay attention to the impact of currencies on their international funds. But that could be changing.
Last year one of the most popular ETFs was WisdomTree Japan Hedged Equity (DXJ), which hedges away currency risk. The fund recorded $10 billion in inflows and now has total assets of $12 billion. What drew the cash was the chance to bet that the yen would weaken and boost Japanese stocks. Plenty of investors figured that the trade would work -- and they were right. By hedging away the currency exposure, the WisdomTree fund outdid conventional unhedged peers by more than 9%.
Only a few ETFs hedge currencies, but demand for the strategy is likely to increase. With interest rates rising in the U.S., the dollar seems poised to climb against many foreign currencies. That is good news for tourists who will be able to buy more souvenirs in Tokyo and Rio de Janeiro. But for international funds, the rising dollar presents a headwind. When foreign currencies decline, the value of overseas holdings drops for U.S. investors. If the yen sinks by 10%, the returns of a Japanese fund would be penalized by about that much. "A case can be made for hedging your entire international exposure," says Matt Hougan, executive vice president of IndexUniverse. "There is more opportunity for the dollar to rise against the euro than for the euro to rise against the dollar."
Investors can hedge with a growing number of funds, including WisdomTree Germany Hedged Equity (DXGE) and db X-trackers MSCI Emerging Markets Hedged Equity (DBEM). The funds use currency forwards and other techniques to insure that returns aren't hurt by currency moves. Because they eliminate currency losses, hedged funds tend to be less volatile than their unhedged peers. Lately most of the hedged funds have enjoyed a clear edge. During the past year, db X-trackers MSCI EAFE Hedged Equity (DBEF), a hedged international fund, returned 22.8%, compared to 19.2% for the unhedged iShares MSCI EAFE (EFA).
But the hedged funds do come with downsides. If the dollar sinks, the value of foreign assets climbs for U.S. investors, and unhedged funds enjoy an edge. With Europe recovering in recent months, the euro has strengthened against the dollar, a move that left hedged funds lagging. During the past year, WisdomTree Europe Hedged Equity (HEDJ) returned 18.5%, compared to 21.6% for iShares Europe (IEV), an unhedged fund. Whether or not they expect foreign currencies to rise, some financial advisers prefer unhedged portfolios because they provide diversification away from the dollar.
