Last November, WisdomTree tinkered with DXJ's benchmark to tilt it toward exporters-companies that have done well as the yen has weakened due to stimulus measures that have sought to bring Japan out of its deflationary doldrums. WisdomTree, the publicly traded New York-based ETF firm, is looking to expand on the blockbuster success it's had with the WisdomTree Japan Hedged Equity Fund (NYSEArca:DXJ) by putting into the regulatory pipeline a small-cap version of DXJ. It's that type of focus on exporters and companies with a global footprint that has helped its broader counterpart, DXJ, do so well.
