Motley Fool Momentum Factor ETF (MFMO)

The Motley Fool Momentum Factor ETF (ticker MFMO) is a rules-based equity fund that systematically selects stocks using momentum — the documented tendency of stocks with strong recent returns to continue outperforming in the near term — filtered through Motley Fool’s fundamental quality lens. Unlike a discretionary growth fund where a manager makes judgment calls, MFMO uses a transparent screening process: it identifies companies that exhibit upward price momentum while also demonstrating durable competitive advantages, strong profitability, and sound management. The fund rebalances quarterly to stay aligned with the current momentum regime.

The momentum signal: capturing the outperformers

Momentum is one of the most robust anomalies in finance. Academic research spanning decades shows that stocks performing well over the past 3 to 12 months tend to continue outperforming over the next few months. This is not a guaranteed pattern — momentum reversals and crashes are real and painful — but as a statistical regularity across long periods and many markets, it is reliable enough to be a tradeable source of returns.

MFMO captures this by screening for stocks that are trending upward in price. The mechanics are systematic: the fund ranks stocks by recent price returns (typically the past 6 to 12 months) and identifies those with the strongest upward trajectories. But a pure price-momentum screen would include any stock that is rising, regardless of fundamental quality — speculative bubbles, promotion-driven rallies, low-margin businesses with temporary hype. That is where Motley Fool’s philosophy enters.

The quality overlay: momentum meets fundamentals

MFMO does not simply buy stocks trending highest. It layers on fundamental quality filters that reflect Motley Fool’s investment approach. The screening looks for companies exhibiting durable competitive advantages (brand loyalty, switching costs, network effects, economies of scale), strong and stable profitability, healthy balance sheets with manageable debt, and earnings growth trajectories that support their market valuations. This means MFMO avoids buying low-quality trash that happens to be rallying temporarily.

The intention is elegant in theory: own profitable, well-managed businesses that the market is just beginning to recognize and reward through higher stock prices. You capture the momentum (the technical signal that the market is rewarding these businesses) without buying speculation divorced from fundamentals. In practice, this hybrid approach — momentum plus quality — can work well when the market is correctly identifying genuinely good businesses, and it can fail badly when momentum crashes or when the market misjudges quality.

Portfolio construction and rebalancing

MFMO typically holds 50 to 100 stocks, weighted either by market capitalization or by composite scores within the model. The portfolio spans sectors but is naturally growth-oriented — momentum by definition captures outperformers, which tend to be growing, change-leaning businesses. Technology and consumer discretionary stocks often carry outsized weight simply because those sectors more frequently exhibit strong momentum and earnings growth.

The fund reconstitutes and rebalances quarterly, meaning the portfolio is refreshed every three months. Stocks that no longer meet the momentum and quality criteria drop out; stocks that have newly emerged with strong momentum and strong fundamentals enter. This quarterly discipline keeps the portfolio aligned with the current market regime rather than becoming a static, stale list of past winners.

Trading frequency and costs

Because the fund rebalances quarterly and holdings change based on the screening process, turnover is moderate to high compared to a buy-and-hold index fund. This translates to trading costs and, in taxable accounts, potential tax consequences. The expense ratio is modest, reflecting the rules-based, systematic nature of the approach — no expensive research team or discretionary trading desk, just a repeatable screening process. The fund trades on an exchange with good liquidity throughout the day.

Cyclical performance and momentum crashes

MFMO’s returns follow the momentum factor’s cycles. When the market is rewarding growth and change-oriented companies — when momentum is in favor — MFMO tends to outperform broad indices. When momentum falls out of favor or when the market reverses sharply, punishing recent winners, MFMO can underperform significantly.

The 2021–2022 transition exemplified this danger. The technology and high-growth stocks that dominated 2021 and led momentum screens became the worst performers in 2022 as inflation, rate hikes, and growth concerns sent the market reeling. A momentum-heavy approach that held the recent outperformers got hit very hard. These momentum crashes are real, they are not rare, and they can persist for years. There is no guarantee that momentum anomalies will continue to exist or that they will profit investors who choose to pursue them.

Another risk is concentration. If a particular sector dominates momentum signals at any time — such as technology during extended bull markets — the fund becomes overweight that sector simply because those names are displaying the strongest momentum. This can amplify sector-specific downturns and create hidden volatility.

Who the fund serves

MFMO appeals to investors who believe that systematic, rules-based factor approaches can outperform over time, who understand the cyclical nature of factor returns, and who want a transparent implementation of momentum plus quality. It also suits investors who like Motley Fool’s philosophy and prefer a disciplined, rule-driven version to discretionary active management.

MFMO is less suitable for investors who cannot tolerate the underperformance periods that inevitably arrive when momentum falls out of favor, or for true buy-and-hold investors seeking pure long-term diversification. Factor-based funds are best for investors who understand the factor’s behavior and can maintain conviction even through extended underperformance cycles.

Research and evaluation

Start with Motley Fool’s documentation of the screening process. Understand the momentum lookback period, the specific quality criteria, the rebalancing frequency, and the expected turnover. Review the current portfolio to verify it matches the screen — are growth stocks overrepresented? Are dividend-paying stalwarts absent? Compare MFMO’s returns to a broad market index over various market cycles, with special attention to periods when momentum fell out of favor, to understand the downside. If you can access historical data, backtest the strategy over 20-plus years. Finally, be honest with yourself: can you maintain conviction in this strategy even if it underperforms for two or three consecutive years? If the answer is no, this fund is not the right vehicle for you.
