Dividend Growth as Defense in a Narrow Market

U.S. equity markets remain unusually concentrated, with a small group of mega-cap stocks driving a disproportionate share of index returns. While that dynamic has rewarded investors in recent years, it has also raised questions about portfolio risk, diversification, and vulnerability to mean reversion. As advisors look for ways to manage concentration risk without sacrificing long-term return potential, dividend growth investing is re-emerging as a potential solution.  

Nick Puncer, managing director and portfolio manager at Bahl & Gaynor, explores how dividend growth strategies can help manage risk while still aiming for competitive long-term returns. 

CM: U.S. equity indices are increasingly dominated by a small group of mega-cap stocks. How should advisors be thinking about concentration risk in client portfolios today? 

NP: There are a few ways to look at the trend of concentration in equity markets. Most advisors have seen first-hand the power of concentration in building wealth. But much of the role of advisors as risk managers and asset allocators is aimed at helping clients preserve wealth. If market concentration is reflected in client portfolios, it may warrant evaluation within the context of a client’s broader allocation and objectives, depending on client goals. 

Market history is a good place to start when thinking about concentration, though past cycles have unfolded differently and may not repeat in a similar manner. The graph below plots the top 10% of stocks by market cap relative to the size of the entire US stock market. At least two observations can be drawn from this chart: 

• Current levels of market concentration have surpassed all prior peaks in modern market history going back to the mid-1920s. 

• Market concentration tends to run in cycles (peaks and valleys).

What may not be as observable is that the current concentration cycle, which began in 2006, is the longest cycle on record and nearly double the historical average cycle length of 10.2 years¹. 

Given this market backdrop, it is very important for advisors and their clients to understand whether their portfolios reflect market concentration and whether that positioning aligns with the client’s goals for investment. 

CM: When you speak with advisors, how are they framing the risk of relying on a small group of mega-cap stocks to drive portfolio returns? 

NP: Advisors and clients are often cautious about altering portfolio positioning that has aligned with market concentration. This is understandable because rising market concentration definitionally signals that a subset of the market has outpaced most other market constituents. It’s highly uncertain how long the current concentration cycle will last, just as it’s difficult to discern whether a bubble is forming at any time and historical concentration cycles have not followed a uniform pattern or timetable. 

Conversations about diversifying concentrated exposure are most productively approached as “and” discussions, rather than an “or” decision. Maintaining some level of ownership in what has worked makes sense. Indeed, top-of-market market constituents are great companies with promising growth trajectories. But there is tremendous opportunity to complement this exposure with additional positioning that can emphasize different objectives. Framing market concentration in terms of downside risk exposure can be helpful because risk exposure is a portfolio characteristic that can be meaningfully augmented through manager selection and asset allocation by an advisor though no allocation decision can eliminate equity market risk. 

We walk advisors and their clients through the following fact pattern: 

• The top 10 S&P 500 constituents by market cap had an average downside capture ratio of 103%² a decade ago. This meant that in a downward market move, the top ten constituents would decline about in-line with the overall market.   

• Today, that downside capture ratio has increased to 138%², meaning the largest companies are more volatile to the downside than the overall market.   

• This is compounded by the top ten constituents representing 40%² of S&P 500 market cap today, more than double their decade-ago level of 18%². 

• Finally, the business models and end markets of the top ten constituents are much more inter-connected today than in the past, which may influence how they respond to certain economic or market developments, though outcomes are uncertain. 

Exposure to these top companies over the last decade has created a lot of wealth, but preservation of this wealth could become a challenge, particularly for clients that now rely on their wealth to support their lifestyle, as in retirement. A concentrated portfolio with excessive downside volatility and regular cash distribution needs can be a dangerous combination in terms of providing long-term financial sustainability to a client. 

CM: Cap-weighted indices have significantly outperformed equal-weighted versions in recent years. Why do you think that gap has become so pronounced? 

NP: The strong performance of cap-weighted indices over their equal-weighted counterparts is mechanical in nature. Equal-weighted indices consistently reduce exposure to the largest index constituents and reinvest these proceeds into companies at the lower end of the weighting (and therefore company size) spectrum within the index. We’ve been in a concentration cycle for two decades, so equal-weighted indexes have been on the “wrong side” of a secular concentration trend. 

Historical data from the Kenneth R. French Data Library yield some interesting observations about portfolio characteristic performance in periods of rising market concentration: 

• Cap-weighted portfolios outperform equal-weighted ones. 

• Large-cap portfolios outpace small-cap portfolios. 

• Growth-tilted portfolios beat their value-tilted counterparts. 

This has likely been the common experience of many advisors and clients possessing portfolio positioning that reflects market exposure and therefore rising concentration. 

But historically when market concentration peaks, the performance of these portfolio characteristics tends to flip. The table below illustrates that, historically, equal-weight portfolios outperform cap-weighted portfolios, small-cap portfolios outpace large-cap portfolios, and value-tilted beat their growth-tilted counterparts in a diversification cycle.

Of course, history does not repeat itself, but it can help inform future positioning. These data suggest that advisors and their clients may benefit from rebalancing portfolios to reflect exposure that may be absent. Equal-weight, smaller, and value-leaning portfolio characteristics are considerably different than the characteristics of currently concentrated market exposure (e.g. cap-weighted, larger, and growth-leaning). It can certainly feel uncomfortable to go against the grain of consensus and what has worked well in the recent past, but differentiated positioning is a precondition for alpha generation potential and market exposure ignores the unique goals most clients set out to meet through investing. 

CM: Many investors see equal-weighted indices as a solution to concentration. Why might shifting to equal weight alone not materially change overall portfolio risk? 

NP: The rationale for utilizing an equal-weighted portfolio to address capitalization-weighted concentration seems solid in theory, but the facts tell a different story. 

The theory goes that an equal-weight index reduces top-of-market concentration present in capitalization-weighted indexes. While this is true, it’s also important to consider where proceeds otherwise invested in these heavyweight companies are allocated. For the equal-weighted S&P 500, top-of-market concentration is transferred to smaller-capitalization companies that can be more volatile. 

Consider the chart below, which plots the beta of the equal-weighted S&P 500 compared to its capitalization-weighted counterpart over 45 years of history. At least three observations are relevant to consider: 

• The average beta of the equal-weighted S&P 500 index over the observation period is 1.07⁷, higher than the capitalization-weighted index. 

• Today, the beta of the equal-weighted S&P 500 index is perilously close to that of the cap-weighted index.   

• 79%⁷ of the time, the equal-weighted S&P 500 has registered a beta higher than its capitalization-weighted counterpart.

These surface-level findings are plainly observable, and often intuitively understood when explained to clients. But we owe a level of deeper scrutiny here. 

The table below outlines several comparative risk characteristics of the equal-weighted S&P 500 versus the capitalization-weighted index: 

Source: Factset, 2025. 

The key takeaways from this table are: 

• The equal-weighted S&P 500 index has greater downside sensitivity than its capitalization-weighted counterpart. 

• The same observation holds for standard deviation of return, implying more volatility of the equal-weighted return series. 

• Kurtosis, a measure of the likelihood of tail events, is higher for the equal-weighted index, signaling fatter tails and the potential more extreme outcomes. 

From practical standpoint, an equal-weight index that replicates small-cap exposure already present elsewhere in a portfolio can push against the intended strategic asset allocation an advisor has thoughtfully constructed for their clients. 

All this indicates that, although advisors may be solving for top-of-market concentration, they may be receiving more volatility than intended. There are other avenues advisors and their clients can pursue to maintain their large cap exposure, but with a meaningfully reduced risk profile, including dividend-oriented or other active approaches, each of which should be evaluated within a comprehensive allocation framework and in light of client-specific objectives and constraints. 

CM: Historically, how have dividend growth strategies compared with broader equity markets in terms of volatility and long-term total returns? 

NP: The risk and return profile of equity cohorts based on dividend policy differ markedly from each other. Based on historical observations, Dividend Growers have at times demonstrated a combination of relatively higher returns and lower volatility relative to the other dividend policy categories (e.g. Dividend – No Change, Dividends Cutters, and No Dividend companies), though outcomes vary across market environments.

Part of this could be related to the cash generative nature of the underlying businesses among dividend-growing companies. Cash return has historically been viewed as a differentiated component of total return relative to capital appreciation alone, so dividend-paying companies may provide both income and price appreciation as components of total return, unlike companies that rely solely on capital appreciation. Dividend growing companies have historically differentiated themselves from the other cohorts because business model durability may support sustained shareholder payouts, though such outcomes are not guaranteed and can vary across market environments. 

In short, the presence of a dividend has historically been associated, in certain periods, with different volatility characteristics relative to the broader equity market. The presence of dividend growth has historically enhanced the return profile of companies with such a policy.  These characteristics may harmonize with a variety of desirable client outcomes and complement diverse positioning in client portfolios. 

CM: Dividend strategies are sometimes viewed as “defensive” or income-only. How do you address that perception with advisors and clients? 

NP: The dividend strategy universe is multi-faceted. One useful distinction between dividend strategies are those that focus on generating only current income versus those that focus on growing portfolio income over time. Too much focus on current income generation can put capital at risk in “value traps”, or companies with growth challenges that may eventually threaten dividend sustainability. Too much focus on dividend growth may deemphasize current income and reduce active share which can negate some of the historical diversification or volatility characteristics that have been associated with dividend approaches. 

Defensiveness is not necessarily an undesirable feature of dividend strategies. Indeed, companies that pay dividends have historically exhibited different volatility characteristics than their non-dividend counterparts. This can be particularly useful when considering the impact of downside volatility, though no strategy can outright eliminate equity market risk. A simple example can be useful to understand the importance of downside protection and capital preservation potential.  

Consider, a 50% loss on an investment would require a 100% return to get back to even. A 60% loss may not seem much worse, but the additional loss would require a 150% return to get back to par. Managing to avoid comparatively little incremental downside has historically had a meaningful impact on long-term compounding, though future outcomes are inherently uncertain. This is only a mathematical example, so it does not consider the instinctual tendency of humans to panic. While historical data and behavioral considerations suggest that drawdown management can be an important component of portfolio construction, approaches should be evaluated within the context of a client’s broader allocation and objectives. 

Balance is likely the ideal characteristic when selecting a dividend strategy. Balance between current income generation with future dividend growth can help to ensure exposure to companies with established cash flows as well as potential for future growth, recognizing that neither attribute is guaranteed. If the stock market functions according to theory, an asset that produces more cash as time passes should be worth more in the future. Hence, a dividend growth strategy with balanced objectives can potentially provide the important benefits of long-term equity ownership, income utility, and volatility reduction though results will vary and should be considered alongside other portfolio tools. 

CM: For advisors worried about a potential mean reversion in mega-cap performance, what practical steps can they take to incorporate dividend growth into client portfolios today? 

NP: A good starting point is understanding the extent of current mega-cap or other concentrations in client portfolios. Advisors are often aware of these exposures already.   

The next step is revisiting goals with clients. The strength of equity markets over the last decade-plus has moved many clients with equity exposure closer to achieving their goals.  Clients may not need to take as much risk as current levels of market concentration may carry. Other clients may benefit from the utility of added income a dividend growth strategy implementation may provide, depending on market conditions and portfolio objectives. 

The final step relates to setting expectations. Dividend growth strategies can potentially solve for a lot of client priorities, but they are not a panacea. Dividend growth strategies often do not keep pace with strong market uptrends, but clients often understand the trade-off in terms of the historical tendency for different return and volatility characteristics relative to the broader market, which may at times involve less upside participation during strong rallies 

The most important function of a financial advisor may be keeping clients invested for the long run. This involves understanding client goals, building a strategic allocation to fit these goals, and honoring the behavioral element of investing for human clients. Dividend growth strategies have historically exhibited myriad potential benefits for clients, and the current market backdrop provides an opportunity for advisors to prepare their clients for the journey ahead.
