Imagine you're building a house. You wouldn't just throw random bricks together, hoping for stability. You'd carefully select bricks based on factors like size, strength, and compatibility. Similarly, factor investing represents a strategy employed by experts to tailor investment recommendations to your individual needs. This method involves crafting a portfolio of stocks based on parameters that signify a specific factor, thereby aiming to optimise investment outcomes. In this article, we'll talk about what factor investing means, what factors it includes, and the advantages and disadvantages associated with this investment approach.
What is Factor Investing?
Factor-based investments involve systematically analysing, selecting, weighting, and adjusting portfolios. This is done in favor of stocks with specific traits that have shown to improve returns while managing risk. Typically, investors access these factors through quantitative, actively managed funds, or ETFs designed to follow customised indexes.
Factor investing finds its roots in the groundbreaking research of Eugene Fama and Kenneth French, who introduced a three-factor model in 1993. This model expands upon the conventional market risk factor by incorporating the risks and returns associated with small and undervalued companies when evaluating asset prices.
Fama and French observed that these factors accounted for a significant portion of the fluctuations in stock returns. Subsequently, other researchers identified additional factors influencing stock returns.
As a result, various methods exist for building factor portfolios. Although definitions and metrics may differ, six factors have gained prominence among academics and investors over time, serving as fundamental elements in portfolio exposure.
The Different Factors in Factor Investing
Size: In their initial identification of the first factor, Fama and French illustrated the presence of a return premium associated with investing in smaller-cap stocks. This phenomenon may stem from the inherently higher risk profile of smaller companies: Typically, these firms exhibit greater volatility and face an elevated risk of bankruptcy, prompting investors to demand compensation for assuming such additional risk. Accessing exposure to small-cap stocks is relatively straightforward through conventional market capitalization methods. For many investors, holding a small-cap fund or ETF offers a simple and relatively efficient means of capturing the small-cap premium. Nonetheless, it's crucial to recognize the higher inherent risk associated with investing in smaller companies.
Value: The second factor in the Fama-French model, known as value, suggests that undervalued stocks have historically outperformed their more expensive counterparts. This concept traces back to Benjamin Graham's value investing philosophy from 1949, advocating for buying stocks below their intrinsic value. Expensive stocks with high expectations offer limited room for error, while cheaper stocks with potential to exceed expectations may yield higher returns. Value investing's success is often attributed to stocks eventually aligning with their earnings. Investors tend to be overly optimistic about expensive, high-growth stocks and overly pessimistic about cheap, slower-growth stocks. When undervalued stocks surpass earnings expectations, they can outperform due to improved market optimism about their earnings potential. Empirical evidence supports the notion that value investing consistently generates excess returns over time. Fama and French's research showed that stocks with high book-to-price ratios outperformed those with lower ratios. Many popular value indexes continue to emphasize this metric, making it easily accessible through available investment products.
Momentum: Momentum investing, akin to technical analysis, involves studying price trends to predict future returns. Empirical evidence of this trend indicates that stocks performing well in the medium term often sustain their momentum, while underperforming stocks tend to continue lagging. The rationale behind momentum investing's effectiveness sparks debates, with many attributing it to behavioral factors. Investors may initially overlook improving fundamentals or company trends until a stock begins outperforming, prompting increased attention and investment. This dynamic perpetuates the cycle of winners continuing to win and sustains momentum investing until a catalyst, such as an earnings miss or overvaluation, halts the trend.
Quality: While investors have long sought high-quality companies, empirical evidence supporting this strategy emerged relatively recently. This delay may stem from the lack of consensus on defining "quality." For instance, research has highlighted that the companies with higher earnings quality or lower accruals (difference between operating cash flow and net income) have outperformed the market over time. Nonetheless, many experts agree that quality stocks typically exhibit higher profitability, stable income and cash flows, and minimal leverage. These attributes often signify competitive advantages, which enable companies to sustainably outperform peers over time. In essence, companies with strong profits, robust balance sheets, and steady cash flows tend to deliver consistent long-term outperformance.
Dividend Yield: The dividend yield factor operates on the principle that securities with higher yields tend to deliver superior returns over time. Essentially, it reflects the return investors expect to receive merely by holding the investment, based on the yield earned. This factor extends across various asset classes and is often termed "carry" in fixed income or currency contexts. While some dividend yield strategies focus on screening companies based solely on their trailing dividend yields, others aim to identify consistent high-yield generators by considering additional metrics such as dividend payout ratio as well.
Low Volatility: A low-volatility approach aims to invest in stocks with lower risk or return fluctuations than the broader market, historically resulting in higher risk-adjusted returns. Research, including studies by Robert Haugen and James Heins, suggests that portfolios emphasising low volatility may outperform the market over time. This strategy benefits investors by offering returns similar to the market but with a smoother ride. Additionally, it can be advantageous to invest in stocks with stable revenues and earnings, less vulnerable to economic downturns. Low-volatility strategies shine during periods of market volatility and rapid declines, as lower-risk stocks tend to hold up better as they experience smaller drawdowns during market downturns. Implementing the low-volatility factor can be done in various ways, such as targeting stocks with minimal price volatility.
Pros of Factor Investing
Diversification: Factor investing allows you to diversify beyond just large-cap stocks, potentially reducing portfolio risk.
Enhanced Returns: By strategically targeting factors with historically higher returns, you may improve your portfolio's performance.
Lower Costs: Factor investing strategies are often implemented through Exchange Traded Funds (ETFs) which typically have lower fees compared to actively managed funds.
Transparency: Factor-based ETFs provide clear visibility into the underlying holdings and the specific factors they target.
Discipline: Factor investing enforces a rules-based approach, potentially reducing emotional decision-making.
Cons of Factor Investing
Performance Chasing: Not all factors outperform in all market conditions. It's crucial to choose factors with long-term validity.
Factor Risk: Concentration in a specific factor can expose your portfolio to higher risk if that factor underperforms.
Limited Alpha: While factor investing offers diversification, it may not outperform the market significantly, especially during periods of high efficiency.
Implementation Costs: Transaction costs associated with rebalancing factor-based ETFs can slightly erode returns.
Less Control: Unlike actively picking stocks, factor investing gives you less control over individual holdings within the strategy.
Key Points to Consider in Factor Investing
Align with your investment goals: Factor investing should complement your overall investment strategy and risk tolerance.
Choose the right factors: Research historical performance and factor correlations in the market.
Consider factor-based ETFs: Explore a variety of ETFs targeting different factors, offered by reputable asset managers.
Maintain a long-term perspective: Factor investing is a marathon, not a sprint. Stay disciplined and avoid emotional reactions to short-term volatility.
Seek professional guidance: Consult a financial advisor to tailor a factor-based strategy to your specific needs.
In Conclusion
Factor investing offers a data-driven approach to potentially enhance your portfolio's returns and risk profile in the market. By understanding the factors at play and carefully selecting strategies aligned with your goals, you can build a more diversified and potentially stronger foundation for your financial future. Remember, factor investing is a tool, and like any tool, its effectiveness depends on how you wield it. Conduct thorough research, understand the risks involved, and consult your investment counsellor before making any decisions.
