Factor investing is familiar to institutional investors. Could it potentially strengthen your portfolio, too?
A core diversified portfolio should involve a blend of growth, value and quality stocks—and actively rotate among them to navigate different phases of market cycles. Growth, value and quality are also three factors with standout historical track records.
Here is an overview of what factors are, how those three important equity factors work and when each one could prove most useful for your core portfolio—and for achieving your investment goals.
Q: What are factors, and what are factor investing strategies?
A: Factors are broad, persistent drivers of risk and returns that investment professionals use to explain why a particular stock may be behaving in a certain way. Some examples of equity style factors are growth, momentum, low volatility, quality, value and size (market cap).
Isolating equity style factors helps us analyze trends, or reasonably consistent behaviors, to discover potentially favorable investing dynamics. Factors can be just as volatile and cyclical as equities (if not more so).
Factor investing involves selecting securities that have these risk and return drivers—favoring specific characteristics at certain times when they have been historically associated with higher returns.
Q: How has factor investing performed over time?
A: Over the last 25 years, three types of factor investing—growth, value and quality—have stood out due to these styles’ distinct attributes and impact on portfolio performance at different phases of the economic cycle.
Each factor and its inherent investment characteristics has a unique focus:
- The growth factor isolates companies with high growth potential based on their sales or earnings outlooks.
- The value factor identifies companies that are trading more inexpensively than their fundamentals (sales, earnings or assets) might imply.
- The quality factor points to stocks with strong and consistent fundamentals.
Q: Should a core portfolio emphasize one factor or invest in multiple factors?
A: A core diversified portfolio should involve a blend of growth, value and quality and actively rotate across factors to navigate different phases of market cycles. Historically, factors have had low correlation with one another, so by blending these three factor strategies, investors may potentially build a more resilient portfolio, according to their risk tolerance and market outlook.
Q: Is the goal of factor investing strengthening returns?
A: Yes, but the decision to invest in a factor strategy isn’t just about seeking the best return. It’s also about adjusting the portfolio’s volatility profile—and consequently, its risk-adjusted returns—because the clients’ experience of the investment journey toward their goals is paramount.
A key tenet of a core portfolio is that it helps you stay invested. If heightened market volatility and drawdowns scare you into selling at the wrong time, historically that has destroyed long-term value creation. For many investors, a smoother journey is vital.
Q: What is growth factor investing? What are the growth factor’s key characteristics?
A: Growth investing focuses on buying shares of companies that may be industry disruptors or have especially innovative products, making them likely to achieve earnings growth above the broader market average. The growth investor isn’t as concerned when a stock seems overvalued using a metric such as the price-to-earnings (P/E) ratio. These rapidly expanding companies often reinvest their profits to fuel further growth (and therefore capital appreciation), rather than paying out dividends.
Growth investors typically look to sectors such as technology and healthcare (and biotech) where innovation drives rapid development and a company’s market expansion.
If you want a regular income stream from your core portfolio, this may not be the best strategy. Growth investors may take profits in place of distributions. If they do so, however, they must be aware of the tax implications, and the possibility that generating liquidity by selling their growth holdings at the wrong time (i.e. during periods of market weakness) could have negative long-term impacts.
Q: When is an example of a time that growth stocks (and the growth factor) did particularly well?
A: Growth stocks outperformed other factors, and the broad market, in 2020, the year of the Covid -induced market drawdown. The MSCI World Growth Index rose 34% in 2020, far outperforming the broad MSCI World Index, which ended 2020 up 16% (Exhibit 1).
Growth stocks’ performance has been driven recently by the technology, artificial intelligence and internet sectors, most dramatically in 2023 and 2024 when the “Magnificent 7”1 dominated the stock market. A similar period occurred as pandemic lockdowns shifted consumer behaviors towards using digital services.
The low interest rate environment during Covid-19 meant these companies also enjoyed reduced borrowing rates, helping their future earnings become more valuable and contributing further to the growth stocks’ attractiveness.
