As the adoption of model portfolios continues to expand, we are seeing a growing number of advisors leveraging third-party portfolios backed by the capabilities of professional asset managers.

At WisdomTree, we believe our Model Portfolio collaboration with industry legend Professor Jeremy Siegel is truly the first of its kind.

Launched in 2019, this suite of open-architecture ETF Model Portfolios provides an innovative solution to advisors seeking to balance their clients’ current income needs while managing longevity risk.

Introducing the Siegel-WisdomTree Model Portfolios

The Siegel-WisdomTree Model Portfolios offer three risk profiles tailored to meet the needs of medium- and long-term investors:

All three Model Portfolios were designed to offer an efficient, low-cost way to apply the core investment principles from Professor Jeremy Siegel’s research, including:

Longer life expectancy requires individuals to rethink their retirement planning and asset allocation.

While the short-term standard deviation of equities is higher than that of bonds, this may not be the most appropriate definition of risk for most investors. Rather, we believe the risk that investors do not reach their retirement goals—shortfall risk—should be weighed more heavily in investors’ minds than the day-to-day fluctuations of the stock market.

With longer life expectancies extending individual investor’s investment horizons, we believe a greater equity bias (structurally allocating more to equities than to fixed income) is warranted in many client portfolios.

Additionally, when viewed through the lens of maintaining purchasing power, equities can help reduce risk, as stocks have historically been an excellent long-term hedge against inflation.

As Professor Siegel’s research below highlights, value and dividend-paying stocks have historically enhanced portfolio returns while experiencing less volatility than growth stocks.

Therefore, the equity allocations of the Model Portfolios tilt toward factors such as dividend yield and low price-to-earnings (P/E) ratios to seek higher income generation and outperformance potential.

A fully diversified, global equity portfolio offers potential for long-term return and risk diversification benefits.1

The models provide diversified exposure to U.S. and international stocks. Although U.S. stocks have outperformed over the past decade2this has not always been the case. Moreover, we believe lower equity valuations found outside of the U.S. could potentially result in attractive returns over the long-term.
