July 2019 optimal portfolios are now available and discussed in terms of recent and long-term market trends

The July 2019 optimal portfolios are now available to subscribers of ETFMathGuy. So, please log in and select your discount broker. In this post, we will also discuss more about risk and return in an optimal ETF portfolio.

As we mentioned in our last post, there are benefits to having more ETFs to choose from during the portfolio construction process. We showed the potential to increase expected returns. In this post, we highlight another important element – risk.

Risk and Return

Risk and return are two fundamental issue that are important to consider when investing in an ETF portfolio. The chart below shows risk (horizontal axis) and return (vertical axis). Here, we define risk as the annual volatility, measured by the standard deviation of daily returns. We evaluate risk and return using a multi-year sample period selected from our rigorous backtesting process. As this chart shows, the optimal portfolios reside at risk levels between the bond market (ticker: AGG) and stock market (ticker:IVV). And, these portfolios are efficient, since they were selected to maximize the expected return.

As this chart shows, cash can be nearly risk-less, based on volatility, but offers returns that may not exceed long-term inflation. Bonds can offer more of a potential return, but with added risk. Even more return is possible from the stock market for those willing to accept additional risk.

What about the last 6 months?

Indeed, it is true that the first half of 2019 has been very good for both stocks and bonds. Based on a recent Wall Street Journal article, “… S&P 500 finished Friday up 17% this year, marking its best first half since 1997 “. According to the site ETFreplay.com, and including dividends, the stock and bond market are up 18.3% and 5.8%, respectively, this year. Will this trend continue? I personally doubt anyone really knows, as I believe that markets are generally very efficient. A better question may be “What level of risk” or “How much exposure” do you want your investments to have in various parts of the market. To end this post, I’ll leave you with one (of many) famous quotes by Warren Biuffet.

“The stock market is a device to transfer money from the impatient to the patient.”

Warren Buffett

Opportunities from more commission-free ETFs

Earlier this month, Fidelity followed through on its promise made earlier in the year. They now offers over 500 commission-free ETFs. This increase puts them in 2nd place for most commission-free ETFs offered by the five discount brokers analyzed each month by ETFMathGuy. The leader is still Vanguard, with approximately 1,800. Our chart below shows the update for Fidelity’s offering, where the Vanguard count only represents Vanguard ETFs. (We will be updating our Vanguard database soon.)

Vanguard* count only includes Vanguard ETFs. Vanguard now offers approximately 1,800 ETFs commission-free.

What is the benefit of more commission-free ETFs in a portfolio?

The most obvious benefit is the opportunity to access portions of the market not previously available. I demonstrated this benefit in previously published research entitled “ETF trading strategies to enhance client wealth maximization“. Here at ETFMathGuy, we have seen these opportunities first hand in our optimal portfolios. Each month, we’ve developed portfolios based on the current number of ETFs offered by each discount broker. We have also calculated the expected return associated with these portfolios, and there appears to be a potential opportunity. When constructing portfolios with more ETFs available, we see in the figure below that expected returns generally improve. Note that the pair of dots next to the portfolios are the result of excluding commission-free municipal bonds when generating a portfolio suitable for an IRA.

More commission-fee ETFs may not always be beneficial

This figure shows that having more options to invest can improve the likelihood of generating higher returns. But, the additional ETFs must be sufficiently different those that are already offered. They must also have the potential to generate higher returns. Ameritrade seems to be accomplishing the most with their approximately 300 ETFs. Conversely, ETrade offers many more ETFs than the 59 offered by Vanguard, but doesn’t appear to increase expected returns by much in the portfolios constructed by ETFMathGuy .

June 2019 Optimal Portfolios are Now Available to ETFMathGuy subscribers

The June 2019 optimal portfolios are now available to subscribers of ETFMathGuy. So, just log in and select your discount broker.

You can now view the June 2019 optimal portfolios for the five discount brokers analyzed by ETFMathGuy. These portfolios cover nearly 1,500 ETFs currently offered commission-free from Ameritrade, ETrade, Fidelity, Schwab and Vanguard.

In all cases, we applied our rigorous portfolio construction process to produce the current portfolios. So, we encourage you to browse through these portfolios to review the following characteristics:

  • Allocation of bond versus stock ETFs in the optimal portfolio
  • Turnover from the previous month or months
  • The effect of risk level on the overall portfolio risk statistics
  • The increase in expected return as risk level increases

We hope you find these portfolios educational!

Where are the ESG funds in the 2019 optimal portfolios?

In our mid-April post, we updated the database used by ETFMathGuy to include the expanded list of commission-free ETFs offered by five discount brokers. We also mentioned one of the most popular themes to hit the ETF landscape, called Environmental, Social and Governance (ESG) investing. For example, Vanguard offers two of these ESG funds.

These two ETFs carry an expense ratio of 0.12% and 0.15%, respectively, consistent with Vanguard’s low-cost philosophy. So, why aren’t these funds appearing in the current portfolios developed by ETFMathGuy?

The short answer is that our portfolio construction process requires a sufficient return history. Based on our backtesting results, we identified an optimal sample period of several years. Unfortunately, the two Vanguard ETFs noted above have only existed since September 18, 2018, or about the last 8 and a half months. Consequently, this history is simply too short for our optimization model to generate portfolios that satisfy investor return expectations.

So, is ESG investing worthwhile?

This is an excellent question! In fact, based on a recent Wall Street Journal article, other experts in the industry shared our concern about a short return history.

“Many of these ESG ETFs are relatively young and have not had a chance to prove if they can demonstrate strong performance”

Todd Rosenbluth, senior director of ETF and mutual-fund research at CFRA

What does this mean for you? Well, if you are an investor focused on using your beliefs to guide your investment decisions, you may find this short history acceptable. However, here at ETFMathGuy, we prefer to make evidence-based decisions. So, we look forward to analyzing longer return histories that may show how ESG funds could be part of an optimal portfolio.

Risks and Opportunities in Fixed-Income ETFs

Fixed-income ETFs (also known as bond ETFs) continue to grow at a rapid pace. Bond ETFs now exist across a wide spectrum of characteristics. Looking for shorter or longer maturity? Or, how about higher yield (aka junk bonds) versus investment grade or Treasury bonds? ETFs even cover the bond markets in both emerging and developed economies worldwide.

At this rate, State Street Global Advisers predicts that assets in bond ETFs could reach $1 trillion by the end of 2019.

What is driving demand?

Like stock-based ETFs, low cost is a big driver. Greater tax efficiency, as we discussed in detail in a post earlier this year, over bond mutual funds helps too. But, the biggest demand could be simply choice.

“Investors really have a lot of choices — more than they’ve had in the past five years. “

Noel Archard, State Street Global Advisors

Liquidity concerns?

Our opinion at ETFMathGuy is that liquidity concerns are minimal. In fact, real-time ETF price availability helps the price discovery process, and should improve liquidity.

“Fixed-income ETFs have been tested more than once over the past 10-11 years, without any major issues. “

Rich Powers, Vanguard

The current focus of fixed-income ETFs

The current focus of fixed-income ETFs is now in portfolio construction. Here at ETFMathGuy, we are helping to lead this initiative by building portfolios to take full advantage of what fixed-income ETFs have to offer. For instance, in the May taxable conservative portfolio for Vanguard, we show a portfolio with a a variety of fixed-income ETFs in it. We also seek to include higher volume alternative ETFs, to mitigate any possible liquidity issues and minimize the bid-ask spread trading costs.

In conclusion, fixed-income ETFs are in important core component of an optimally diversified portfolio. We invite you to browse through the current month optimal portfolios to see the importance of bond ETFs.

May 2019 Optimal Portfolios are Now Available to ETFMathGuy subscribers

The 2019 optimal portfolios for the month of May are now available to subscribers of ETFMathGuy. Just log in and select your discount broker.

You can now view the current optimal portfolios for the five discount brokers analyzed by ETFMathGuy. These portfolios cover nearly 1,500 ETFs currently offered commission-free from Ameritrade, ETrade, Fidelity, Schwab and Vanguard.

Portfolios now include updated ETF lineups from Ameritrade, ETrade and Vanguard

As we mentioned in our last post, Ameritrade, ETrade and Vanguard expanded their commission-free lineup. So, the portfolios for the month of May now consider these new funds. Here is a simple count of the number of commission-free ETFs now available from our five discount brokers. Note that IRA accounts exclude the 46 municipal bond ETFs discussed in our recent article.

Commission-free ETFs for Taxable and IRA accounts, as of April 30, 2019

However, this lineup change does not significantly alter the ETFMathGuy portfolios. Remember that several years of price history are necessary to build optimal portfolios. So, ETFs that haven’t been around very long will not be considered as part of the later stages of the portfolio construction process.

Unsure of which discount broker to pick?

If you haven’t yet settled on a discount broker that offers commission-free ETFs, consider the following. Last month, we showed the updated expense ratios and bid-ask spread for Fidelity and Schwab’s commission-free ETFs. Below is the updated information for our other three brokers, Ameritrade, ETrade and Vanguard.

Expense ratios, as of April 2019, for commission-free ETFs offered by Ameritrade, ETrade and Vanguard.
Expense ratios, as of April 2019, for commission-free ETFs offered by Ameritrade, ETrade and Vanguard.

It is pretty clear that, when it comes to expense ratios, Vanguard is the clear winner. The same can be said for Vanguard’s advantage with generally lower bid-ask spreads.

Bid-ask spreads, as of April 2019, for commission-free ETFs offered by Ameritrade, ETrade and Vanguard.

Bid-ask spreads, as of April 2019, for commission-free ETFs offered by Ameritrade, ETrade and Vanguard.

So, is Vanguard the best broker for commission-free ETF portfolios?

This is an excellent question. In terms of number of commission-free ETFs, Schwab is the leader. But, on the basis of cost, Vanguard is the clear winner. What about diversification? Perhaps the diversification benefit of the Schwab (or some of the other discount brokers) can offset their higher costs? We will explore this topic in a future blog post. Stay tuned!

April 2019 Optimal Portfolios are Now Available to ETFMathGuy subscribers

The 2019 optimal portfolios for the month of April are now available to subscribers of ETFMathGuy. Just log in and select your discount broker.

You can now view the current portfolios for the five discount brokers analyzed by ETFMathGuy. These portfolios cover over nearly 1,500 ETFs currently offered commission-free from Ameritrade, ETrade, Fidelity, Schwab and Vanguard.

What’s new? Full ETF names, portfolio & benchmark statistics, and portfolios for taxable and IRA accounts.

So, what’s new this month? First, we’ve added the full name of the ETF, so that subscribers don’t need to look up individual ticker symbols. For instance, the portfolios continue to favor the utility sector. So, for example, the Vanguard portfolio lists both the ticker “VPU” and its full name, “Vanguard Utilities ETF”, in the portfolio tables.

Second, we’ve added portfolio annualized statistics for expected return and volatility. Now, it is clear what the risk levels are set to in portfolio construction, regardless of the discount broker. For the month of April, annualized risk levels were

  • Conservative: 5.7%
  • Moderate: 8.3%
  • Aggressive: 11.0%

Third, we’ve added benchmark statistics. These measures are an excellent way to understand how the optimal portfolios match up to the broad stock, bond and cash benchmarks used by ETFMathGuy.

Last, but not least, we’ve run our portfolio construction process to include and exclude municipal bond ETFs. As mentioned in our recent post, brokers like Fidelity often restrict the use of municipal bond ETFs in IRA accounts. The summary table at the top of the current portfolios now indicate either Taxable or IRA (no munis).

We hope you find these 2019 optimal portfolios insightful and educational! If you enjoyed reading this post, we hope you will share it with others in your personal or professional network. Just click one of the icons below. And, for a limited time, subscriptions are free!

ETFs to Mitigate Volatility and Enhance Diversification

Last week’s Wall Street Journal noted that Charles Schwab Corp. and Fidelity Investments have doubled the number of commission-free ETFs they offer.

This is good news for individual investors! More investment options can help enhance diversification and consequently, mitigate volatility.

Here at ETFMathGuy, we build portfolios to do just that…minimize volatility using our proprietary software. In fact, our approach addresses the exact point made by Ben Johnson’s quote, director of fund research at Morningstar. In the article, he states:

“As people stop obsessing over fees, they’re coming to realize that what matters most is portfolio construction. “
