Market volatility returned in September 2020. In this post, we discuss this recent surge in the context of long-term historical volatility. We also show how our ETFMathGuy portfolio performed, and elaborate on a source of that performance.
Market Volatility returned, but will it persist?
Earlier this year, we developed an app to automatically measure stock market volatility. This app updates daily, and the figure below shows the latest result.
We also provided a table showing the distribution of long-term historical volatility, as observed over more than 20 years. Current volatility is 19.7% as of October 2nd, which corresponds to the upper limit of the third-quartile. So, while market volatility returned, it is still well below the volatility seen in early 2020.
Market Performance through the 3rd Quarter
The higher volatility occurring in September did indeed correspond to a loss in the stock and bond markets. The stock market lost 3.7% and the bond market lost 0.1%, based on the ETFs with ticker symbols IVV and AGG. The year to date return of these stock and bond index ETFs were 5.5% and 6.7%, respectively, including dividends. The year to date return of the ETFMathGuy Aggressive Risk Portfolio was 20.8%. This return is the result of trades conducted in a brokerage account at Fidelity Investments, and so includes the bid-ask spread.
Premium subscribers now have access to the October 2020 premium portfolios, as well as a handy rebalancing calculator. Free subscribers are welcome to log in to review older premium portfolios through May 2020, or upgrade their account to enable premium access.
Sources of Excess Performance
One ETF that our portfolios have consistently included throughout this year is the Aberdeen Standard Physical Palladium Shares ETF (ticker: PALL). Its 12 month return and volatility appear below next to the S&P 500 ETF (ticker IVV).
Examining these results for PALL confirms the expectation that higher risk can lead to a higher return. Our optimal portfolio construction process creates a portfolio that, along with PALL, finds other ETFs that maximize expected return. This process also keeps the portfolio’s expected risk between the stock and bond markets. Additionally, we backtested this process over a full market cycle. We hope you will consider upgrading your subscription to gain insights into a wider variety of ETFs that appear in our efficient portfolios.
