Is it time to boost exposure to the Value factor?

Risk isn’t a bad thing – when it’s intentionally, carefully added to a portfolio in an effort to boost returns. But hidden risks are what keep investors and financial advisors up at night. Over the past year, the Invesco Global Solutions team examined hundreds of financial advisor portfolios, and we discovered that a common source of hidden risk is unintended factor exposures that could impact the ability of the portfolios to achieve the outcomes they are looking for. Fortunately, there are ways to diagnose and address this problem.

What are factors?

Factors are measurable characteristics of a security that help explain its performance. Whether they know it or not, most investors already has exposure to factors – the key is understanding and managing that exposure in a way that aligns with an investor’s investment objectives.

What did our analysis reveal?

One way that we help advisors is through our Custom Portfolio Analysis (CPA) service. Recently, we compiled data from 121 CPAs performed in the second quarter of 2018, to assemble an up-to-date snapshot of portfolio construction insights.

Our analysis of equity factors uncovered that, on average, these portfolios had a structural underweight to the Value factor as well as significant biases to the Size and Momentum factors (Figure 1). Factor exposures are not mutually exclusive; however, a large tilt into any one factor may result in unwanted concentration risk that leaves portfolios vulnerable to changes in the market cycle.

Why is this significant?

Figure 2 below shows that Value has exhibited negative correlation to Size and Momentum.  Combining lesser-to-negatively correlated factors can help increase diversification, reduce concentration risk and volatility. Therefore, if a portfolio is overweight to Size and Momentum while underweight to Value, it may not be nearly as diversified as investors believe.

Each factor is a subset of this index. Past performance does not guarantee comparable future results. An investment cannot be made directly into an index.

What does this mean for investors?

We believe these findings present a compelling opportunity in the current market environment. According to our research, Value has historically outperformed Size and Momentum during high volatility periods and in early contraction (Figure 3). This may be particularly useful given our capital market expectations over the next five years point to increasing volatility across most major asset classes.

Each factor is a subset of this index. Past performance does not guarantee comparable future results. An investment cannot be made directly into an index. Early contraction scenario represented is stress-tested and is calculated by applying historically observed shocks to current exposures.

Key takeaway: Diversify equity factor exposure with Value

For portfolios that are underweight Value, adding exposure to this factor could potentially increase diversification, reduce concentration risk and provide downside risk mitigation this late in the market cycle.

A bull market is an environment in which stock prices are rising or are expected to rise.

A bear market is an environment in which stock prices are falling and widespread pessimism causes the stock market's downward spiral to be self-sustaining.

Factor investing is an investment strategy in which securities are chosen based on certain characteristics and attributes that may explain differences in returns. There can be no assurance that performance will be enhanced or risk will be reduced for funds that seek to provide exposure to certain quantitative investment characteristics ("factors"). Exposure to such investment factors may detract from performance in some market environments, perhaps for extended periods. Factor investing may underperform cap-weighted benchmarks and increase portfolio risk.
