NEW YORK (Fabian Capital Management) -- One of the hottest ETFs of the year has been the WisdomTree Japan Hedged Currency ETF (DJX), which hit an intraday high in May and has since fallen nearly 18% over the last 10 trading sessions.Prior to this selloff, DXJ had posted gains of over 46% in 2013, which put it in the top 1% of ETF performers this year. According to Index Universe, DXJ is the top gatherer of new assets this year, with investors pouring over $7.6 billion of new money into this surging economy. As you can see on the chart below, DXJ has fallen below its 50-day moving average and appears poised to continue its recent descent. At times like these I am reminded of the adage that "the bigger they are, they harder they fall." This appears to be the case with DXJ as early investors are more than likely taking profits and standing aside at this juncture.
