The term smart beta
is becoming more and more popular in describing indexes that, in short, diverge from a typical market capitalization-weighted
approach. With such indexes, we believe that it is critical to understand the different tilts and biases introduced by the stock selection and constituent weighting rules of each index. Today, we’re taking a deeper look into our broad-based international smart beta indexes and examining how our smart beta (aka fundamentally weighted) approach has performed internationally. Specifically:
• Did these indexes tend to increase or decrease sensitivity to movements of the market?
• Did they tend to tilt more toward larger
or smaller stocks?
• Were they more value
-oriented, more growth
oriented or somewhere in between?
• Was there a similar anti-momentum
bias as seen in the U.S., intuitively coming from our annual rebalance?
Thanks to data published regularly on the Kenneth French Data Library, we are able to do a returns-based analysis that seeks to quantify answers to these questions through the process of regression
. We compared the broadly focused, developed international WisdomTree Indexes to the appropriate MSCI EAFE Index
benchmarks and show their respective value and growth cuts.
Factor Exposures of International Equity Indexes

Market Factors Takeaways:
In our U.S. factor analysis, discussed in an earlier blog post
, the dividend-weighted indexes showed lower “market factor” sensitivity or market factor loadings. On the international front, the market sensitivity factors more closely resembled the traditional market cap-weighted indexes with readings close to 1.0. One reason for this is that the U.S. is an outlier country in terms of dividend payout ratios
. Internationally, the indexes provide greater representation and coverage of international markets. The indexes therefore provide market sensitivity close to the broad-market indexes.
Value Factor Takeaways:
All WisdomTree-related strategies listed above weight securities by their Dividend Stream®
. These strategies tend to tilt more toward the value segment of the markets. However, for the broad WT DEFA Index
, the value loading is almost identical to that of the MSCI EAFE Index. Furthermore, the WT International LargeCap Dividend Index
had a value loading lower than that of the MSCI EAFE Index. One reason for this is country allocations. Japan, for instance would show a low price-to-book value ratio and may represent considerable weight in the value factors, whereas on a dividend basis, Japan is under-weighted compared to a market cap-weighted index. This would lead to a natural bias in dividend strategies away from loading to the value factor that has greater exposure to Japan on a price-to-book value basis.
o The value factor is particularly strong in dividend strategies focused on small- and mid-cap segments. Although the small-cap segment has a much stronger value tilt than the mid-caps, both have a much larger tilt to the value spectrum than the broad market strategies.
o Note that the market cap-weighted
value MSCI EAFE Mid Cap Value
and MSCI EAFE Small Cap Value
Indexes were more value-tilted than the dividend-weighted approach. The dividend weighting therefore was between the traditional market cap-weighted indexes and the value segments of those indexes when measured on sensitivity to this value factor.
Size Factor Takeaways:
In terms of size tilts, WT DEFA, WT DEFA Equity Income
and WT International LargeCap Dividend have the biggest large-cap tilts when compared with all other strategies listed above. In other words, the three strategies have the “purest” large-cap return attribution in the developed international space. When we look at the WisdomTree strategies focused on the small-caps, we cannot describe these Indexes as solely exposed to the small-cap premium. Instead, the WT International SmallCap Dividend Index
has an equally notable tilt to the value segment, through a methodology that weights its constituents by dividends.
o The capability to access multiple tilts within one indexing strategy is an important point to note. As we have previously discussed, Fama/French1
has shown the persistence of both a small-cap and a value premium, both of which can be accessed by the WT International SmallCap Dividend Index.
Momentum Factor Takeaways:
While dividend strategies in the U.S. tend to display strong anti-momentum tendencies, it is less clear in the developed international space. Many of the WisdomTree strategies still have a small tilt toward being anti-momentum.
Knowing Factor Exposures can Help with Portfolio Construction
Knowing these factor loadings
, in our opinion, is only a first step. The critical question regards how to apply this information to portfolio construction. In a future blog post, we will examine how we might go about building a portfolio that matches the size exposure of the MSCI EAFE Index but uses different mixes of WisdomTree Index tools to get there.
