When I speak at investment conferences across the country, the subject of the clever but polarizing phrase “smart beta
” often comes up. Once the obligatory comments are made about how much people hate the phrase or how hard it is to define, the conversation typically turns to the category of passive
investment choices that the term attempts to summarize. For WisdomTree, when we talk about smart beta
, what we are really talking about is a new generation of index-based products that empower investors to explore the core of their portfolios in an attempt to generate better risk-adjusted returns
compared to traditional benchmarks.
On the international front (EAFE
), this means re-examining basic beliefs about whether to take on currency risk in an investor’s core international equity exposure. In recent months, as the dollar has rallied dramatically against both the yen and the euro, interest has turned to strategies that give U.S.-based investors ways to own foreign stocks, while neutralizing foreign currency fluctuations that may move against them. This makes sense.
Currency exposure is a separate and distinct source of risk in an investor’s portfolio. Currency-hedged
portfolios give investors a way to benefit from international equity performance without being penalized by—or rewarded for—movements in foreign currencies.
Over the last 20 years, exposure to developed world currencies has not added to overall stock returns, although it has added volatility
. By examining the historical returns of the MSCI EAFE Index
—both with and without exposure to currency—we can examine what happens to the risk/return profile of international stocks when the currency impact is removed. In the table below, we see how significantly the beta
of MSCI EAFE is reduced (in blue) when currency is removed from the equation.
Currency Consistently Added to Risk and Beta of International Stocks

If an investor had targeted the local returns of EAFE for the past three, five, 10 or 20 years, the returns would have been higher without the currency exposure than with it. Moreover, currency exposure added several percentage points of incremental volatility to international equity exposure in each period shown above, going back to 1970. And while having the currency exposure may have provided some diversification benefit several decades ago, the correlation
between the EAFE currencies and the S&P 500
has been rising in the past decade compared to where it had been over the past 20 or 40 years.
All this raises a question: Should investors be 100% unhedged
in their core international equity exposure, especially given the low cost of hedging developed world currencies today with interest rates
in Japan and Europe at or below 0%?
One way to help generate higher risk-adjusted returns is by reducing overall volatility. The other is by generating returns that exceed those of a comparable cap-weighting index. In WisdomTree’s case, we have been doing so with several of our broad-based Indexes that have some of the longest track records in the fundamentally weighted indexing space.
Smart Beta International Equities: Real-Time Results
For example, the WisdomTree DEFA Index
, a broad measure of the dividend-paying segment of developed equity markets outside the U.S. and Canada, has outperformed the MSCI EAFE Index by 90 basis points (bps)
on an annualized basis since its inception in June 2006 for more information on the WT DEFA Index, click to this recent blog post
For investors looking to access the same equity methodology of the WisdomTree DEFA Index while mitigating the impact of foreign currency movements, WisdomTree recently launched a currency-hedged version of the WisdomTree DEFA Index called the WisdomTree International Hedged Equity Index.
The WisdomTree International Hedged Equity Index mitigates the impact of 12 distinct foreign currencies, and it does so with an estimated annual cost to hedge of just 0.13%. Because the Index of some 2,300 dividend-paying stocks is dividend weighted and rebalanced annually, it will have different country and sector weights than the MSCI EAFE Index. The International Hedged Equity Index also exhibits a higher trailing dividend yield
—3.98% as of June 19, compared to a trailing dividend yield of 3.12% for the MSCI EAFE Index.
Conclusion: Creating Higher Risk-Adjusted Returns over Time Can Create Value for Investors
Using dividend-paying stocks and dividend weighting, the WisdomTree DEFA Index has helped to generate higher returns compared to the MSCI EAFE Index over the last nine years. If WisdomTree can reduce volatility even further by removing the impact of foreign currencies, the WisdomTree International Hedged Equity Index
may represent a valuable tool for investors looking to push the efficient frontier even more to the north/northwest quadrant.1
For investors interested in the strategy, the WisdomTree International Hedged Equity Fund is designed to track the performance of the WisdomTree International Hedged Equity Index before fees and expenses.
