What Happened
Bill Miller IV, son of famed investor Bill Miller III, brings a unique perspective to conviction investing, grounded in his background in economics and his experience at McKinsey. He initially pursued a career in baseball before transitioning to investing, influenced heavily by his father's relentless truth-seeking approach and time management skills. Miller IV emphasizes the importance of understanding investor behavior and price trends, noting that most assets are efficiently priced and the challenge lies in identifying undervalued opportunities.
At Miller Value Partners, Miller IV holds a strong conviction in Bitcoin, describing it as a superior form of capital governance compared to gold. He argues that Bitcoin's energy-intensive creation process and promise of stability separate it from state control, making it an appealing investment. His firm has allocated about 10% of one of their funds to digital assets, including Bitcoin, reflecting this belief.
Miller IV highlights the significance of probabilistic fundamental value in making investment decisions. He uses daily performance reports to track and adjust portfolio positions, ensuring alignment with investment goals. Despite Google's leadership in AI, it was removed from their portfolio when deemed fairly valued, illustrating the disciplined approach to portfolio management.
The current market environment is reminiscent of 1999, with AI leading a narrow market, according to Miller IV. He sees undervalued opportunities in Small and MidCap value sectors, along with potential growth in the energy and utilities sectors. His approach involves high conviction investing, characterized by concentrated positions and high active share, reflecting his belief in the importance of deep understanding and commitment to selected investments.
Miller IV employs AI tools daily to save time and enhance decision-making, recognizing the shift from monetary to fiscal policy in the post-financial crisis era. He points out that the once costless capital environment favored massive growth stocks, a condition that has now changed. He also discusses the concept of housing prices needing to appreciate over mortgage rates to safeguard people's primary savings vehicles.
Books play a significant role in Miller IV's philosophical and practical framework. He is currently reading 'The Mattering Instinct' by Rebecca Goldstein, which aligns with his interest in the psychological aspects of investing. He also finds value in stoic philosophy, as seen in Mel Robbins' 'Let Them' and Marcus Aurelius's 'Meditations', which emphasize focusing on controllable factors. 'The Psychology of Money' by Morgan Housel is recommended for its insights into personal finance and long-term wealth creation strategies.
