Checking In on the Siegel-WisdomTree Model Portfolios

Chief Investment Officer, Model Portfolios

This article is relevant to financial professionals who are considering offering Model Portfolios to their clients. If you are an individual investor interested in WisdomTree ETF Model Portfolios, please inquire with your financial professional. Not all financial professionals have access to these Model Portfolios.

We last wrote specifically about the Siegel-WisdomTree Model Portfolios back in August 2021. It is time for an update.

Before we dive in, let’s remind ourselves of the investment mandates we were solving for when we launched these models back in 2020.  

First, most investors have four common investment objectives with respect to their investment portfolios (though each person’s “weighting” to an objective may differ):

1. Generate sufficient current income to maintain or improve their current lifestyle
2. Do not outlive their money (i.e., make sure the portfolio lasts at least as long as they do)
3. Ensure that family legacy or impact/philanthropic goals can be met
4. Minimize fees and taxes along the way

These common objectives face two primary challenges as we look out over the investment horizon.

1. Low interest rates: While interest rates are rising (a trend we believe will continue, with fits and starts), the absolute level of rates remains low by historical standards. It is true that the Fed has embarked on what most investors expect to be an aggressive “rate hike regime” as it belatedly acknowledges it is “behind the curve” on inflation, but given that it started from a baseline of zero, even an aggressive rate hike regime will result in modestly low absolute rates.

Not until late April/early May did Treasury real levels of interest rates move into slightly positive territory across most of the yield curve, suggesting investors still are locking in low real returns if they buy and hold those bonds until maturity. 

U.S. Treasury Real Yields (%)

At the same time, while credit spreads have widened year-to-date (“YTD”), they remain well within historical levels.


The implication is that it will remain difficult to generate sufficient current income out of a fixed income portfolio to maintain or improve current lifestyles without taking unwanted additional risk (i.e., increased duration or credit risk).

2. Lower forecasted equity returns: The potential return on any investment is at least partly a function of what you pay for it today. Despite the YTD market declines, equity market valuations do not represent “screaming buys” by historical standards (though they appear more attractive in small- and mid-cap stocks). Our own estimates are for roughly 5% real return versus a historical real return rate of 6.5%–6.7%.


The implication is that it may be more difficult to build portfolios that have a sufficient longevity profile to accommodate increased life expectancies without taking on additional equity risk.

So, the question becomes—how can we build a “better mousetrap” to the traditional "60/40" portfolio that can potentially address most investors’ objectives in the face of current and expected future market environments? Fortunately, there are things we can do. 

Drawing on the research of Dr. Jeremy Siegel of the Wharton School (a since-inception strategic investment advisor to WisdomTree), we know that, over a reasonable time horizon, stocks have done better than bonds, and even the worst historical periods for stocks have been better than that of either bonds or cash.

Maximum and Minimum Returns 1802 - 2020

Additionally, current dividend yields from the equity markets remain comparable (though currently lower) to the nominal 10-Year Treasury yield. We argue, however, that equity dividend yields are more sustainable as they represent a return on real assets. In addition, equities hold the potential for upside total return, while bonds do not (if held to maturity).


The Siegel-WisdomTree Model Portfolios

It was with these “facts on the ground” that, in collaboration with Dr. Siegel, we constructed the Siegel-WisdomTree Model Portfolios—a Global Equity model and the “flagship” Longevity model. The Longevity model is explicitly our attempt to build a “better mousetrap” to the traditional 60/40 portfolio:

1. A targeted (but not fixed) 75% allocation to yield-focused equities to improve current income generation, the longevity profile and the legacy potential of the overall portfolio (Investor Objectives #s 1, 2 and 3). The yield-focused nature of the selected equity securities means they tend to have a lower equity beta profile.
2. A targeted (but not fixed) 25% fixed income allocation that is constructed for quality income generation in a risk-controlled manner and to function as an appropriate equity risk hedge (Investor Objective #1).
3. The portfolio is constructed entirely with ETFs to potentially optimize fees and taxes (Investor Objective #4).

When we say “targeted but not fixed” allocations, it simply means that we have the ability to deviate on a marginal basis as market conditions change. Currently, the portfolio is 72/22/6, with a 6% “alternatives” allocation to managed futures and commodities (funded equally from equities and fixed income). 

We built the Global Equity model on the same principles but in recognition that many advisors prefer to manage their own fixed income portfolios and/or want to create different risk profile portfolios than our suggested 75/25.

The potential results of our asset allocation, portfolio construction and security selection decisions are:

1. Improved current income generation
2. A better longevity profile (i.e., reduced short-fall risk)
3. Better potential for funding legacy objectives
4. An expected slightly higher standard deviation than a traditional 60/40 portfolio. That is, the investor and advisor are accepting slightly higher short-term volatility in exchange for increased current income and a better longevity profile.

We launched these models in late 2019, so they now have more than two years of live performance under fairly extreme market conditions (in both directions), and so far, they have performed as expected from both a total return and a yield perspective. The current 6% allocation to “alternatives” reflects the fact that we hold positions in managed futures and broad-basket commodities to mitigate the perceived risks of rising inflation.

We launched the Siegel-WisdomTree Model Portfolios in an attempt to address what we believe are some of the primary issues and conditions that investors will face into the foreseeable future. Our view is, simply, that the traditional “60/40” portfolio will face significant headwinds in meeting investor objectives as we move through this decade and the next. We believe we have succeeded in constructing a “better mousetrap.”
