Analysis

The Motley Fool 100 Index ETF (TMFC) is a passively managed fund targeting the US large-cap growth segment, currently managing over $1.77 billion in assets. The ETF has demonstrated robust performance, delivering 16.92% year-to-date and 24.02% over the last year as of October 16, 2025, and holds a Zacks ETF Rank of 1 (Strong Buy) based on expected asset class return and momentum. This performance aligns with the general characteristic of growth stocks excelling in strong bull markets.

The fund exhibits significant sector concentration, with approximately 43% allocated to Information Technology, and its top 10 holdings, including Nvidia (NVDA) at 10.34%, Microsoft (MSFT), and Apple (AAPL), comprise 62.06% of total assets. While TMFC holds 103 stocks to diversify company-specific risk, its beta of 1.11 and a three-year trailing standard deviation of 18.94% indicate higher volatility inherent to its large-cap growth mandate.

TMFC's annual operating expense ratio stands at 0.5%, which, while noted as being on par with some peers, is considerably higher than major alternatives such as Vanguard Growth ETF (VUG) at 0.04% and Invesco QQQ (QQQ) at 0.20%. These alternatives also command significantly larger asset bases, with VUG at $194.11 billion and QQQ at $386.53 billion, potentially offering greater liquidity and scale benefits.

Key Decisions for Investors

• Investors should carefully evaluate TMFC's 0.5% expense ratio against lower-cost, larger-scale alternatives like VUG (0.04%) or QQQ (0.20%) for similar large-cap growth exposure.
• Consider the fund's substantial concentration in Information Technology (43%) and its top 10 holdings (62.06% of AUM) when assessing portfolio diversification and potential sector-specific risks.
• Acknowledge the higher volatility metrics (beta 1.11, standard deviation 18.94%) associated with this large-cap growth strategy, recognizing its potential for underperformance in non-bull market environments.
