In the Winter 2025 Letter, Shinya Deguchi of Star Magnolia Capital reflects on the psychological and structural elements of long-term investing. Drawing on the dramatic recovery of Carvana (CVNA) and the compounding history of Berkshire Hathaway (BRK-B), Deguchi argues that investors sustain longer time horizons when they invest in people and judgment rather than business abstractions. He asserts that 'distance' from trading platforms is key to avoiding overtrading. Operationally, the firm ('The House of Mulans') maintains a strict capacity constraint of 10 relationships per analyst to maintain depth, which led them to 'quit' four manager relationships in 2025 while adding four new ones. Finally, due to frothy market valuations in the Americas, the firm is actively shifting and diversifying its geographical exposure toward Asian and European managers.
Long-term compounding is best achieved by anchoring capital to high-quality people/managers and maintaining structural distance from market noise to prevent overtrading. Ongoing evaluation requires having the courage to actively 'quit' underperforming managers to optimize limited analytical attention.
The firm believes that market valuations in the Americas are currently frothy and expects the trend of increasing geographic diversification towards Asia and Europe to continue for a while.
As of Jan 30, 2026
Lead Portfolio Manager
Neutral / Balanced
Market Conviction
Star Magnolia Capital functions as an advisory firm with a highly diversified set of 34 approved external manager relationships rather than a concentrated portfolio of direct stock holdings. Because they do not explicitly size single-stock holdings and act on a non-discretionary advisory basis, their direct position-level conviction is fundamentally low-moderate.
Growth Outlook
The manager explicitly notes that US market valuations are 'frothy' and expresses near-term caution regarding regions like Indonesia, prompting a defensive geographic diversification away from the Americas.
Risk Appetite
The firm is maintaining a balanced asset allocation strategy, actively terminating underperforming relationships (four in 2025) while adding four new ones to keep risk exposures stable.
Capital Deployment
The firm added four new managers and terminated four managers in 2025, representing a balanced and net-neutral rotation of capital.
Forward Guidance
As an advisory firm, Star Magnolia focuses on long-term relationships and does not provide near-term trade signals, choosing instead to slowly rebalance geographic exposures to Asia and Europe.
Language Signal
The writing is highly retrospective and philosophical, discussing the mechanics of relationship termination and long-term holding patience, with very little extreme directional rhetoric.
Perceived Risk
Valuations in the Americas are described as 'frothy,' and the manager lists specific structural underperformance risks like manager complacency, mental fragility, and asset size growth.
Opportunity Density
Opportunities are described selectively, with the firm seeking to identify managers in Europe and Asia while finding US valuations too expensive to deploy capital comfortably.
Time Horizon
The manager highlights a 10 to 20-year horizon for durable compounding, notes a minimum 3-year period to evaluate a relationship, and targets average relationship lengths of 10 to 12 years.
