- Market Efficiency as a Model: Ben Felix emphasises that market efficiency is a framework, not absolute reality. While prices reflect available information, anomalies like meme stocks (e.g., GameStop) don’t invalidate the model—they highlight its limitations in explaining irrational behaviour.
- Economic Growth ≠ Stock Returns: Academic research shows no positive correlation between GDP growth and equity returns. Fast-growing sectors often dilute shareholder value through capital raises and competition, as seen in the dot-com bubble.
- Passive Investing Nuances: Felix advocates systematic tilts (e.g., small-cap value stocks) over naïve market-cap weighting. The Fama-French five-factor model (market, size, value, profitability, investment) underpins his strategy, though he cautions against high-turnover factors like momentum.
- Crypto’s Structural Flaws: Felix critiques crypto’s libertarian roots and lack of intrinsic value. Research indicates crypto primarily serves speculative purposes, with behaviour mirroring lottery-style investments. Regulatory arbitrage and technological idealism fail to address systemic financial needs.
- Investor Psychology Pitfalls: Individual investors underperform active funds due to behavioural biases. Crypto adoption often correlates with prior speculative trading habits, reinforcing its high-risk profile.
Felix’s approach combines academic rigour with practical portfolio design, prioritising peer-reviewed research over market narratives. His scepticism towards crypto aligns with historical lessons from technological revolutions, where broad sector bets often yield poor returns despite transformative potential.
For Australian investors: Felix’s emphasis on low-cost, evidence-based strategies resonates with retirees seeking stability. The ASX 200’s concentration in financials and materials underscores the value of global diversification to mitigate sector-specific risks.
