The big idea is to build a proxy for investing outside the U.S. based on risk weighting the component holdings, as opposed to a simple market cap weighting used by many index funds like the iShares MSCI EAFE ETF (EFA).
The process begins with a liquidity screen across 35 developed and emerging markets. The countries are weighted by risk -- the less risky a country the greater its weight in the fund. The process for country weighting is proprietary, but Vident discloses that it considers growth, soundness of money, political stability and valuation.
Vident also considers momentum at the country level and prospects for growth at the corporate level.Results of this process puts each country into quintiles. The top scorers get an overweight of 25% vs. a "baseline" portfolio; the second is over weighted by 12.5%; the third is equal weighted; the fourth is underweighted by 12.5% and the fifth is underweighted by 25%. The process produces an index that is heaviest in Malaysia at 4.97%, Hong Kong at 4.78% and China at 4.09%. What Vident refers to as "emerging Asia" is the largest region in the fund at 27.4% -- twice the weight in the MSCI All Country ex U.S. World Index which, like EFA, is market cap weighted. VIDI's exposure to developed Europe is 25% vs. 45% for All Country World Index ex-U.S.; there are extreme differences for all the regions. The index underlying VIDI has 999 holdings -- the largest being Samsung at 0.47% -- so there's no single stock risk reasonably taken by fund holders. It is, of course, noteworthy that the portfolio construction process concludes that emerging markets are generally less risky than developed markets. Indeed, many Asian markets are on firmer footing in terms of debt levels, budget deficits and various growth metrics. However, this has likely been the case for years and did not prevent those markets from dropping as much as, or even more than, their developed counterparts.
