Looking at Smart Beta: A Focus on the Size Factor

We think it’s interesting to consider blending WTLDI with mid-cap options in order to bring the weighted average size exposure into alignment with that of the S&P 500 Index, and the two mid-caps we use are the WisdomTree MidCap Earnings Index (WTMEI) and the WisdomTree MidCap Dividend Index (WTMDI).

The conclusion:

• An allocation of 77% WTLDI / 23% WTMEI achieved the same size factor as the S&P 500.

• An allocation of 64% WTLDI / 36% WTMDI achieved the same size factor as the S&P 500. WTMDI had a bigger size factor than WTMEI and thus more was necessary to lower the overall size factor to the S&P 500’s.

The WisdomTree Earnings 500 Index (WTEPS) also has more of a large-cap bias than the S&P 500, and we analyzed what combinations targeted the S&P 500 size factor. They are:

• 91% WTEPS / 9% WTMEI

• 85% WTEPS / 15% WTMDI

As people consider ways in which to potentially outperform the S&P 500 on a risk-adjusted basis, we believe that these are examples of one approach that could be of interest. It also shows that as one looks to add in the WisdomTree large-cap options, there is a large-cap bias to construction relative to the S&P 500 that could impact desired allocations in other segments.
