How to Understand a Portfolio’s Risk Exposure

Data from Morningstar’s Global Risk Model provides a new way to measure the risk exposure of a portfolio  

Tom Whitelaw, Morningstar Research Services LLC

 

There are several ways financial advisors can assess a portfolio’s risk. It’s essential to understand both a portfolio’s risk exposure and how it impacts the sources of return within that portfolio to help clients answer questions like: “Is my portfolio overexposed to risk from oil fluctuations?” Or, “Is my portfolio too concentrated in small-cap stocks right now?”  

The Morningstar Global Risk Model provides a powerful new tool by allowing Morningstar Direct℠ users to make comparisons across portfolios and benchmarks on a standardized, objective basis. Users can create custom market scenarios, perform what-if analysis on market movements, and gauge their portfolio exposures to as many as 36 distinct factors. 

Here, we highlight how the tool can help evaluate funds’ exposure to certain risk factors

How to measure the valuation risk in a portfolio 

The Global Risk Model uses the Valuation factor to evaluate how cheap or expensive an overall portfolio is compared with Morningstar’s Quantitative Fair Value Estimate (which is based on the dollar amount we believe a company is worth today). 

For example, the chart below maps out a few aspects of the Valuation factor exposure for Hotchkis & Wiley Large Cap Value (HWLAX): 

  • The preponderance of blue bars in positive territory shows that this portfolio has been, for the most part, historically cheaper than the market. 
  • The horizontal black lines on each bar indicate what the Valuation exposure factor of the relevant Russell 1000 Value benchmark has looked like over the past five years. (Note how the Russell 1000 Value Index itself moved back into overvalued territory in 2018.) 
  • The red line indicates the premium associated with this factor over the cumulative five-year time period, showing that it underperformed for three years starting in 2015. However, while the strategy’s move into deeper-value territory was painful, it paid off toward the end of 2018 (the value premium noticeably strengthens in the fourth-quarter sell-off).

How to measure the competitive advantages of a portfolio 

Another important factor when considering a portfolio’s risk exposure is its competitive advantages over similar companies. The Global Risk Model measures this with the Morningstar® Economic Moat™ Rating, which assesses the strength and sustainability of a firm’s competitive advantages. 

The chart below shows how two funds in the same U.S. Large-Cap-Blend Morningstar Category can take shape differently based on this metric.  

  • Vanguard Dividend Growth (VDIGX) has historically been focused on finding companies with sustainable business models and high barriers to entry that can enable them to keep growing their dividends.  
  • Oakmark Select Investor (OAKLX) has historically been less concerned with traditional moats and more concerned with buying businesses it thinks the market is undervaluing. As a result, its exposure to the economic moat factors sits well below that of its peers.  

The chart also includes DFA International Small Cap Value (DISVX), which demonstrates how a fund with very few moat stocks would look.

How to evaluate a portfolio’s size factor 

The Size factor measures the market capitalization of stocks in a fund’s portfolio to identify where they fall in the market-cap ladder. Take Oppenheimer Global Opportunities (OPGIX), for example, which has historically had a significant exposure to the small-cap factor relative to its U.S. Fund World Small/Mid Stock Category.  

As shown on the chart below, this started to change in 2017 when it moved into larger stocks following a period of strong performance that led to rapid asset growth (assets under management ballooned from around $5 billion in early 2017 to almost $10 billion at the end of June 2018).

Understanding risk exposure to increase your value 

Researching funds requires an understanding of management’s resources, experience, financial incentives, strategy, and long-term track record, in addition to costs and the strengths of the investment organization—therefore, it serves as a key way that financial advisors can help increase their value to clients. 

By understanding this data and its implications, financial advisors can help educate clients about their risk exposure and help empower them to make strategic decisions about their portfolios.
