Motley Fool Money: Why Investors Earn Less Than Their Funds, and the Small-Cap Surge

Date: September 27, 2025
Host: Robert Brokamp
Guest: Jeff Patak (Managing Director, Morningstar)

Episode Overview

This Saturday edition of Motley Fool Money dives into two central topics for long-term investors: the recent surge in small-cap stocks and the persistent phenomenon where fund investors earn less than the reported returns of the funds they own. Host Robert Brokamp reviews the week’s market highlights and then interviews Morningstar’s Jeff Patak about the "Mind the Gap" study, a recurring analysis that investigates why investor returns often lag behind fund returns.

Key Discussion Points & Insights

1. Market Recap: The Small-Cap Surge

[00:05–04:53]

• Small-cap performance:

  • The Russell 2000 (small-cap index) surpassed its 2021 high on September 18, 2025, continuing a strong summer for smaller stocks.
  • For the period since August 1:
    • S&P 500 returned 6.2%
    • Nasdaq 100 (QQQ) returned 7.2%
    • Vanguard Russell 2000 ETF returned 11.3%
    • iShares Microcap ETF returned 15.7%

• Possible drivers:

  • Small-caps have lower valuations (forward P/E of 15.7) relative to the S&P 500 (22.6) and “Magnificent Seven” (30.3).
  • Anticipated Fed rate cuts are particularly helpful for smaller firms that rely on bank loans with floating rates.

• Federal tax update:

  • New law allows workers to deduct up to $25,000 in qualified tips; phases out at higher incomes.
  • Applies to most tipped jobs, but not tips automatically added to bills.
  • Only impacts federal taxes, not payroll taxes.

• Bond market tidbit:

  • Investment-grade corporate bonds’ yield spread over Treasuries is down to 0.75%, the lowest since 1998.
  • "The fact that investors aren't really requiring that much extra yield is a sign that they're very optimistic, perhaps even exuberant." – Robert Brokamp [04:21]
  • Implication: Possibly tilt toward Treasuries if extra yield doesn’t justify risk.

2. Main Interview: Why Investors Earn Less Than Their Funds

[05:55–20:14]

A. Mind the Gap Study – An Overview

• Purpose & Methodology:
  • Most fund returns assume a lump sum invested at the start and held to the end (“time-weighted”).
  • “Dollar-weighted”/Investor returns account for cash flow timing—when real investors buy in and pull out.
  • "What we’re trying to measure with a dollar-weighted return is the return of the average dollar that’s invested in a given investment… and the difference should give us a sense of the impact of buys and sells along the way." – Jeff Patak [06:21]
  • Study covered over 25,000 funds and ETFs, analyzing cash flows and net assets.

B. Key Findings

• The Gap:

  • There’s a consistent gap: investors earned 1.2% per year less than the funds’ stated returns over the last 10 years.
  • "It works out to around 15% of the total returns weren’t captured." – Jeff Patak [08:36]
  • Over decades, this compounds, diminishing overall wealth by 20–30%.

• Why does this gap exist?

  • Timing: Investors often buy after periods of outperformance (buy high) and sell after declines (sell low).
  • Life events and circumstances can force suboptimal timing, not just emotions.
  • "It's not always just ‘bad behavior’—sometimes circumstances just don't go your way." – Jeff Patak [08:36]

C. What Contributes to the Gap?

• 1. Cash Flow Volatility:

  • Funds with more volatile inflows/outflows (i.e., more trading) see larger investor return gaps.
  • "The more investors do, in this case in a transactional sense, the less they tended to earn of their funds' total returns… the takeaway: do less, stay still." – Jeff Patak [11:32]

• 2. Fund Return Volatility:

  • Highly volatile funds also present more challenges for investors to capture returns.
  • Volatility induces emotional reactions: chasing performance after big gains or fleeing after losses.
  • "When you see those wider amplitudes of performance, there’s just a greater propensity for investors to act in ways that we might consider to be rash." – Jeff Patak [12:02]

• 3. Fees & Costs:

  • Relationship between expenses and the investor gap is less clear due to crosscurrents (e.g., low-cost ETFs may invite more trading, narrowing the benefits of lower fees).
  • Lower-cost funds still outperform on average:
    • "It was almost a perfect stair step pattern of outperformance from cheapest to priciest." – Jeff Patak [16:09]
    • Start with cost as a screening metric.

• 4. Fund Type & Automation:

  • Investors in allocation funds (e.g., target-date funds) capture more of their funds’ returns.
  • Automation helps:
    • "The less you do, the more you earned is the clear takeaway…" – Jeff Patak [16:53]
    • Retirement plans, where choices are limited (“gilded cage”), help investors avoid harmful trading.

D. Actionable Advice

• Build in a Margin of Error:
  • Don’t assume you’ll achieve the stated rate of return; actual results are usually lower due to behavioral gaps.
  • "It may not make sense just to assume you’re going to earn a market rate of return. You might want to haircut that a little bit just knowing…we might be given to trading at inopportune times." – Jeff Patak [19:17]

3. Closing Reflections: The Jonathan Clements Story

[20:40–END]

• Tribute to Jonathan Clements, personal finance writer, who passed away at 62 before fully enjoying retirement.
• Life lesson: Plan for the long haul but don’t postpone meaningful experiences; enjoy some of your “retirement” goals sooner.
• "Don't put off everything until retirement. Life and health are uncertain... If possible, enjoy some of your retirement goals now while you can." – Robert Brokamp [20:40]

Memorable Quotes & Moments

• "The less you do, the more you earned is the clear takeaway for us from the study." – Jeff Patak [16:53]
• "Starting with cost is the way to go...it was almost a perfect stair step pattern of outperformance from cheapest to priciest." – Jeff Patak [16:09]
• "It works out to around 15% of the total returns weren’t captured." – Jeff Patak [08:36]
• "Don’t put off everything until retirement. Life and health are uncertain...try to do some of it now while you can." – Robert Brokamp [20:40]

Takeaways for Listeners

• Small-cap stocks had a pronounced rally in late summer 2025, outperforming large caps.
• Fund investors, on average, earn significantly less than their funds’ reported performance—mainly due to mistimed buys and sells.
• Minimizing trading, sticking with lower-cost funds, and using automated investment tools like target-date funds can narrow the return gap.
• When planning for your financial future, include a margin of safety in your return estimates.
• Balance long-term planning with living in the present—don’t wait until retirement to pursue your dreams.
