. Wien had this to say about Japan: "The Japanese economy remains lackluster and the yen declines to 100 against the dollar. The Nikkei 225 continues the strong advance that began in November and trades above 12,000 as exports improve and investors return to the stocks of the world's third largest economy." With a gain of almost 13.4 percent in the past month, DXJ is clearly participating in investors' reborn bullishness toward Japanese stocks. What is important to remember about DXJ is that it does not need Japan's domestic economy to be strong to move higher. That is because the index tracked by the ETF uses a screening feature to weed out Japanese firms that are highly dependent on their home nation for the bulk of their revenue. If Wien is correct in his Japan outlook, DXJ could prove to be one of this year's best-performing developed market ETFs. For more on ETFs, click
