Wealthfront Review – Your Online Financial Investment Advisor



wealthfrontWealthfront is an online financial advisory firm that provides a low-cost way for people to diversify their investments among a variety of asset classes according to the precepts of modern portfolio theory, a concept pioneered by the Nobel Prize-winning economist Harry Markowitz. Markowitz showed mathematically that by combining multiple asset classes into a single portfolio, investors could achieve better performance with less risk than a mere arithmetic analysis would suggest.

Modern portfolio theory, or MPT, has since become the guiding light for many institutional investors and individual portfolios alike.

What Is Modern Portfolio Theory?

Modern portfolio theory is a technique investors use to combine different investments to maximize their returns for a given level of risk. Alternatively, they may use MPT techniques to try to minimize their theoretical exposure to risk for a given amount of return.

The approach is based on assumptions about how asset classes behave, including the expected return and variance of each asset class, as well as the correlation between each pair of asset classes. It’s especially important for investors to form proper forward-looking return expectations when constructing portfolios using MPT.

An MPT theorist may notice that while both asset A and asset B sport long-term returns of 10% per year over the last 20 years, they tend to move in opposite directions a significant amount of the time. For example, they may find that high-yield bonds and real estate investment trusts tend to move in opposite directions 40% of the time. In mathematical terms, the two investments therefore have a relatively low correlation coefficient, and therefore tend to balance each other out. This results in less overall volatility, while still allowing the investor a reasonable expectation of the same long-term return they each provide individually.

The lower the correlation coefficient, the more theoretical diversification benefit a new asset brings when added to the portfolio. The MPT investor seeks to combine assets to gain the most diversification benefit possible, consistent with a targeted return.

MPT and Indexing

While MPT isn’t necessarily predicated on indexing, the indexing strategy translates extremely well to using MPT approaches to building a portfolio. Consequently, Wealthfront’s approach is index-based, and relies on exchange-traded funds to capture the performance of the different asset classes in their portfolio.

You may be saying, “Big deal. Everybody does that! Why don’t I just buy the Vanguard Bond Market Index, the Vanguard Total Stock Market Index, season to taste with a few percentage points of the Vanguard REIT Index and the Vanguard Emerging Market Index, and be on my way? Heck, why not even a target fund?”

Well, you could do that. And if you did, you’d be well ahead of a lot of people. But Wealthfront adds features and expertise you won’t get from simply opening an unassisted account with Vanguard or another low-cost, no-load mutual fund company.

How Wealthfront Works

Users log into the site, and immediately begin to answer risk tolerance questions.

1. Answer Risk Tolerance Questionnaire
There are about 10 questions, which are all very easy and intuitive, and require less than a minute to complete.

2. Receive Portfolio Recommendation
Next, Wealthfront recommends a portfolio and asks if you want to open an account. It’s that simple, really.

The Wealthfront Portfolio

The portfolio Wealthfront recommends is simply based on your responses to the risk management questions. An allocation is suggested using these five asset classes:

  • U.S. stocks
  • Foreign developed markets
  • Emerging markets
  • Real estate/REITs
  • Natural resources
  • Bonds

In addition, Wealthfront also recommends a specific exchange traded fund for your allocation to each asset class. In my case, Vanguard ETFs were recommended for each category except for natural resources, for which the iPath DJP ETN was recommended.

The site goes further than that, though. It actually provides a rationale as to why each selection has been made. For example, the iPath fund was selected for me because it is less energy-heavy than other ETFs in its category, and therefore presumably more diverse. Expenses were comparable to the competition, but the iPath fund isn’t structured as a partnership, and therefore doesn’t issue a K1 form, which could cause tax headaches come next April.

Key Features

Wealthfront has the following features:

  • A “gauge” that quantifies your risk tolerance level on a scale from 1 to 10.
  • The ability to change your answers to see what happens to your recommendations.
  • A graph of the historical performance of the recommended asset mix against the various component asset classes.
  • The estimated probability of gain vs. loss, based on the historic volatility of the components of your recommended portfolio, over as much as 10 years.
  • Support for traditional IRAs, Roth IRAs, SEPs, and SEP IRA accounts.
  • $5,000 minimum account size.
  • No advisory fee on accounts under $25,000. The fee is a reasonable 0.25% on your assets after that, each year. That is more than most popular index funds, but less than nearly any actively managed fund.
  • SIPC protection (Wealthfront opens your account via Interactive Brokers).
  • Interactive Brokers also charges a commission of $0.0035 per ETF share it buys or sells on your behalf.

1. Simplicity
Sure, it’s best to have a financial advisor sit down with you over a couple of hours and complete a very detailed fact-finder. However, a lot of people never get around to that. Wealthfront, on the other hand, sticks simply with the securities side of the equation and is able to boil down the process to its very essence: How much risk are you comfortable taking?

2. Effective Risk Tolerance Questionnaire
Of course, trying to define and quantify risk tolerance is like trying to hang a smoke ring on a hanger. So Wealthfront comes at the equation from a few different directions, and measures not just your stated risk tolerance, but also the consistency of your answers. If you state you are very risk tolerant in some ways but not in others, the Wealthfront model actually dials back your risk exposure.

This is a very smart idea. Most people overestimate their tolerance for risk – it hurts more to lose 50% than it feels good to gain it, and losses are more damaging to portfolios than unexpectedly modest gains, particularly when you need to draw income from that same portfolio.

3. Low Expenses
If you use Wealthfront, it may also save you a good deal in fees. The website’s ETF approach is at least as effective, statistically, as relying on active managers to identify winning stocks – and Wealthfront generates these returns at a fraction of the cost of actively managed mutual funds.

4. Ease of Diversification
Most working stiffs don’t have much business trying to identify individual stocks – particularly at asset levels of under a few hundred thousand to a million dollars. There just isn’t enough money available to meaningfully diversify, unless you use funds of some sort.

Wealthfront’s approach is successful in saving the retail investor the significant fees that actively-managed mutual funds charge. It also results in a much more diversified portfolio than most lay people would ordinarily select on their own.

5. Expertise
Wealthfront also taps its expertise to see what the “smart money” is doing, and builds its own model portfolios based on what professional, sophisticated money managers at educational institutions are doing with their endowments.


1. Insufficient Emphasis on Valuation

MPT also involves a very strange idea of risk. Consider two people walking down the street: One is an efficient market theorist and modern portfolio theory adherent, and the other is a traditional Warren Buffett-style value investor. The second man says, “Oh, look! I think I see a dollar on the sidewalk!” and goes over to pick it up. The MPT investor says, “Nonsense. If there were really a dollar on the sidewalk, someone like you would have picked it up already!”

The moral of the story: Modern portfolio theory has its limitations. It’s not a holy writ to be blindly followed. The professional investors at the endowment funds are well aware of this, and Wealthfront does manage to mitigate this limitation of MPT by keeping one eye on what the pros are doing at the institutions, and building portfolios accordingly. That said, extremely high or low valuation levels could sustain for an extended period of time before mean reversion occurs. The exact timing and magnitude of mean reversion is largely a difficult guessing name.

2. Lack of Insured Options and Guaranteed Investments
Another disadvantage is that none of the asset classes represented in the Wealthfront menu are guaranteed or risk-free. This is fine for institutions, which have unlimited theoretical lifespans. But in the real world, people do have a financial life cycle, and a bear market that would be an inconvenience to an institutional fund (even as they use continued donations and other revenues to scoop up assets at bargain prices) would be a disaster to an individual, who cannot afford a bear market in stocks in the early years of drawing his or her portfolio down in retirement.

In addition to considering the asset classes Wealthfront uses, many families can be well served by allocating a portion of their resources to products with some guarantees in them, such as annuities, participating whole life insurance, and CDs.

3. Home Is Disregarded
Wealthfront’s system assumes that you plug in pretty much everything you own into their model. Their system is not optimized to take into account your exposure to various classes in your 401k, and disregards the role your personal residence may play in your portfolio. But if you own a home, you have a substantial exposure to the real estate asset class already. You may want to make some adjustments to counter this if you use Wealthfront.

Wealthfront is fine for allocating the part of your portfolio you want to put to risk, in the hope of better-than-money market returns. But it does not substitute for a holistic approach to financial risk management.

If you have a fairly simple financial picture – for example, if you’re single, or you and your spouse both work, have no children, and are fairly young and in a position to take some risk – Wealthfront may be just the ticket. The combination of instant diversification across multiple asset classes and very reasonable fees, plus the nod toward risk mitigation at the outset and a rational strategy for rebalancing, can serve you very well, as long as you keep your eye on the big picture.

Don’t expect Wealthfront to do everything for you. It can, however, do quite a bit for you with the portion of your portfolio you expose to market risk – that is, stocks, bonds, mutual funds, and REITs. Indeed, it’s probably just as good as a lazy fee-only planner, but at a fraction of the cost.

It is probably not as good as a very good fee-only planner, however, because the good planners have a broader view of your finances, goals, and risk tolerance. If you have a more complex financial situation, consult a professional planner – preferably one with a CFP or ChFC designation, or comparable experience.

Wealthfront is also not a system for those who take a DIY approach. Wealthfront doesn’t allow you to hold individual stocks or do much in the way of mixing and matching ETFs within your Wealthfront account, though you can tweak your allocations.

Final Word

If you have a straightforward financial situation, are fee-conscious, and have better things to do than research ETFs and stress over your portfolio, Wealthfront is an excellent system to use. Just bear in mind its limitations, and only allocate to Wealthfront the part of your portfolio you are willing to expose to risk.

    I lead the asset allocation effort at Wealthfront. Thanks very much for writing such a comprehensive review about us. We greatly appreciate it.

    I just want to clarify some of our thinkings that are not obvious on our website —

    MPT: MPT doesn’t require one to use rear mirror views. In fact, you can plug any forward-looking views into the framework. We formulate long-term expected returns of the asset classes based on their risk profiles and use them to guide asset allocation decisions. We tend to believe the market is efficient on the macro level for the long run, but we do consider asset return forecast from well know valuation shops such as GMO.

    Insured/guaranteed investments: Most of our clients are young. In addition to advising them to putting aside emergency funds for rainy days in bank accounts, we recommend them to take some risk appropriate for their risk tolerance as we believe the risk will be rewarded and it’s essential to build up their wealth. Life insurance is not our expertise, and we refer interested clients to financial planners or insurance experts.

    Home: The motivation of using REITs in our portfolios is primarily to seek robust rental income from diversified real estate portfolios across the country, and in addition the asset class is a good diversifier. It’s very different type of real estate exposure than home ownership.

    Once again we appreciate you writing the review that’s very helpful for educating individual investors. Please feel free to reach out to us, and we would like to hear what you think.

    As a fee-only planner I’m curious as to how once defines “lazy” fee-only planner vs. a “very good” fee-only planner.

    I’m not familiar with Wealthfront, but your article does a nice job of laying out the pros and cons as an intro.

  • Katy Bolding.

    Wow!!!! !thank you for the information on the Modern Portfolio Theory. Know that one caught my eyes.

    I pay for articles written and posted in
    financial blogs.

    Thank you.

  • Ian Johnson

    Thanks for writing this article. I am young and fairly new to investing and have been weighing my options, with Wealthfront being one that I’m considering so it was very helpful for me to see the pros and cons so well laid out.
