Factors: Separating the Wheat from the Chaff

As the market fragmentation continues, we examine how factors are chosen and constructed, diving deep into the methodology of strategies that can replace or complement active mandates in your portfolio

Jan. 21, 2022

An alternative to active strategies

In previous editions of THE VAULT, we explored factor investing, as well as various strategies to integrate factor-based ETFs into one’s portfolios. In this issue, we will deconstruct the underlying methodologies to reveal how rules-based smart or factor beta” exposures can enhance returns.

Factors can help family offices and investment counsel firms to screen for, or control, systemic risks, and even eliminate idiosyncratic risks that don’t provide returns. As such, they can be a direct replacement for active mandates, providing both risk mitigation and alpha generation over the long term. However, when evaluating a specific factor, there are several aspects worth taking into consideration:

  • Does the characteristic enhance portfolio diversification?
  • Is the construction primarily defensive, or does it help complement returns?
  • Are there compelling benefits across all market conditions?
  • Is it tradeable across the cycle?

Risk and factor investing

Factor analysis can help investors allocate assets to styles that have performed well across different phases of the economic cycle. MSCI has identified six that have excelled consistently over long-term cycles, though with varying levels of risk corresponding to the overall market.

This chart indicates that low volatility, dividend and quality have provided outperformance for less risk relative to the broad index from which they were constructed. by contrast, size, momentum and value have also delivered superior performance, albeit with a higher risk profile than the broad index.

Under the hood: Factor methodologies

It’s important to remember that not all factor-based solutions are built on the same set of rules. As a result, due diligence should evaluate not only the strategy’s objectives but also its underlying methodology, as the latter could create unintended portfolio risk.

As noted above, unconstrained methodologies may lead to additional exposure to sector concentration and interest rate sensitivity (this could occur with Low Volatility or Dividend). Constrained methodologies, on the other hand, may constrain the factor’s effectiveness (and performance) since it may track the parent index’s risk exposure.

BMO’s approach to its factor-based solutions combines both attributes (i.e., objective and weighting), which we use when completing our analysis and making empirical decisions on asset selection. This includes yield-weighting for dividends; a fixed number of securities for both quality and enhanced value, ranked according to relevance; and inverse beta-weighting for low volatility.

Let’s take a closer look at each of these factors in order to gain a better appreciation for their purpose, use case and construction process.

A closer look at low volatility

Low volatility investing is one of the largest and most surprising opportunities to earn alpha. Investors have an inherent belief that return is related to risk, inferring that higher risk should lead to higher returns. However, studies have shown that the low volatility anomaly holds true across markets, with low beta stocks outperforming the broad market over the last 90 years.

This phenomenon challenges the conventional wisdom about risk and return, showing that strategies with a primary focus on capital preservation can actually do better than the broad benchmarks. Moreover, this principle is not localized; it has been observed across the globe. The fact is, low volatility stocks have shallower dips during a market drawdown, which allows their value to compound from a higher level in a rebound and beyond. This is particularly important for Canada, where a large part of the economy is cyclical.

From the outset, our team created a proprietary methodology for low volatility – we’re the only Canadian ETF provider using beta rather than standard deviation or minimum variance as our risk measure. we did this because beta measures systemic risk rather than idiosyncratic risk, an important distinction for institutional investors who manage liabilities and need to remain vigilant of the macro environment.

Furthermore, individual stocks can have a low standard deviation while still having a high beta; there’s no guarantee that they will display a defensive nature in a broad market correction. Standard deviation can vary quite remarkably for a variety of reasons, while beta is a more enduring, predictable measure to manage risk.

Diving into the dividend universe

Dividend is another area where we have constructed a proprietary, rules-based methodology, this time focused on sustainable dividend growth. Yield has historically been a significant contributor to total return; evidence shows that the market rewards companies whose management team demonstrates an ability to increase sustainable yields on a consistent basis.

The selection universe consists of those securities that meet market cap and liquidity requirements. From there, we screen for eligible companies that have paid dividends for a minimum of 3 years and have a positive or flat 3-year dividend growth rate. The remaining securities will then be sorted based on the total dividends paid out, helping to reduce the value tilt and capture more capital growth in the portfolio.

The implications of quality factors

Investors looking to generate alpha for their portfolios often focus on earnings growth as an indicator of companies that will outperform. This is captured to some extent in our proprietary Dividend methodology, however it’s more obvious when using the quality screen. Stable earnings growth is the fundamental principle identified by Graham & Dodd, which states that a company can be valued by understanding the predictability and durability of their profit over time (Graham and Dodd, Security Analysis).

The quality factor

  • High-quality stocks can be components of well-constructed portfolios
  • MSCI defines high-quality stocks as:
    • High return on equity (ROE) – Winners”
    • Low earnings variability – Consistency”
    • Low financial leverage – Can withstand economic downturns”
  • Companies tend to have strong, competitive moats
  • Screening for these metrics provides access to a portfolio of companies with sustainable, competitive advantages

Although quality is on the lower end of the risk spectrum, as was noted earlier, this factor has generated strong results despite its defensive posture. This can be attributed to the sturdiness of the companies held within the portfolio, their respective balance sheets and their proven track record of sustainable growth, which is backed by long-term tailwinds.

Our methodology ensures that each company is assigned, in equal weights, a quality score consisting of three noteworthy variables – a high return on equity (ROE), low earnings variability and low financial leverage. rather than assigning the portfolio by market capitalization, these quality scores help us to optimize exposure in the index composition.

A unique perspective on value

Value is often one of the most misunderstood factors since investors instinctively assume it is a conservative one that captures companies trading at a discount to the market. However, this may not always be the case. As a pro-cyclical factor, value can be out of favour for extended periods of time but outperform when economies surge.

The BMO MSCI Canada Value Index ETF (ticker: ZVC) and the BMO MSCI USA Value Index ETF (ticker: ZVU) use an enhanced value methodology that employs three critical metrics for assessing the value of a company – low forward price-to-earnings (P/E) and enterprise value-to-cash flow from operations (EV/CFO), both of which eliminate potential value traps, plus a price-to-book (P/B) that’s below average. Sector exposures are maintained in the same proportion to the broad index. The chart below outlines our approach in more detail.

The value factor

Source: MSCI, July 2021. For illustrative purposes.

  • Low forward price-to-earnings (P/E)
    • Indicates a company is less expensive than its peers who have similar earnings projections; signals a market mispricing
  • Low price-to-book (P/B)
    • Identifies companies that are less expensive than their peers
  • Low enterprise value-to-cash flow from operations (EV/CFO)
    • Enterprise value reflects all sources of capital, debt and equity. Therefore, evaluating enterprise value will screen out companies that are highly financially leveraged. Lower EV companies with high levels of operating cash flow indicate a value company.

The selection universe begins with a neutral parent index and then adjusts towards the value factor by using our three, core metrics equally weighted to a composite z-score, which is then scored by sector, producing a final value score that is multiplied by the company’s market cap.

Factors in changing macroeconomic conditions

It’s important to note that not all Factors will have the same macroeconomic drivers as a tailwind. Some will outperform others based on variables like inflation, the interest rate environment and the current phase of the economic cycle. That’s why building a portfolio based in part on each of these 6 factors is key to optimizing returns – and lowering risk.

The performance of factor exposures also depends on how they are combined. When conducting your due diligence on the suitability of a factor, investment counsellors and family office practitioners should look not only at the macro environment, but the correlation of that factor with the rest of the portfolio.

Fortunately, the proliferation of factor or smart beta ETFs in recent years has led to a wide offering that gives institutional investors the freedom to mix and match products to their specific requirements, requiring little in the way of time, resources or implementation expertise.

When balanced with effective risk management, the research shows clearly that factors optimize performance over the long term. They allow you to separate the wheat from the chaff, ensuring each exposure provides optimal returns for a level of risk.
