Nobody may have any interest in shorting the U.S. stock market right now. Yet futures traders are growing increasingly excited about the prospect of shorting certain currencies. In particular, bets that the Japanese yen will fall against the greenback are at their highest levels since the summer of 2007. Granted, a contrarian might think that a high degree of short interest is an indication that Japan’s currency could actually strengthen against the dollar. However, trend analysis suggests otherwise.

The price of the CurrencyShares Japanese Yen Trust (FXY) is below both its 50-day and 200-day moving averages. For most trend-followers, this suggests that yen depreciation may have further to go. From my vantage point, though, I would need to see the yen break through the 52-week lows set back in May. If that turned out to be the case, I might anticipate capital appreciation from WisdomTree Japan Hedged Equity (DXJ). The exchange-traded tracker has had a difficult time recapturing its springtime highs due to the fact that the yen has not quite capitulated.

In a hedged equity investment like DXJ, one garners the benefits of Japan’s heightened capacity to export without losing money alongside a depreciating currency. In an unhedged equity investment like iShares MSCI United Kingdom (EWU), however, one might find he/she is underperforming when the underlying currency (i.e. British Pound) is at a year-to-date peak.  Notice in the chart below that the current price of CurrencyShares British Pound (FXB) is back at 2013 highs and that its 50-day moving average crossed above its 200-day moving average in mid-September. Since the cross-over, SPDR Trust S&P 500 (SPY) has gained 5.9% whereas EWU has only tacked on 2.5%.

While an investor in EWU is getting a currency lift in his/her investment when the British pound rises against the U.S. dollar, he/she is bumping up against the perception that British companies in EWU’s basket cannot perform well when the pound is reaching new heights. Personally, I expect the pound to lose value as Federal Reserve tapering concerns begin taking a toll on the euro, pound and yen. Yet the technical evidence for a weaker British pound has not yet materialized.

If you believe that the British currency is due for a pullback, and you like the prospects for British equities, you could consider the recently introduced db X-trackers MSCI United Kingdom Hedged Equity Fund (DBUK). The dollar volume is a bit too light for my tastes, though I am looking forward to the day when DBUK has more assets under management.

What about the euro? CurrencyShares Euro Trust (FXE) took a noteworthy hit when the European Central Bank found itself with few alternatives; it lowered its refinancing rate to 0.25% last month. Nevertheless, FXE has been charting a path of higher lows since early July. That has made the unhedged Vanguard Europe (VGK) stronger than WisdomTree Hedged Europe Equity (HEDJ) for the last 5 months. On the other hand, if the European Central Bank (ECB) continues making overtures to weaken the eurozone’s common currency — if you see value in European corporations that trade at lower price-to-sales ratios than their U.S. counterparts — depreciation in FXE could herald outperformance for HEDJ.
