With policy rates still restrictive and risk premia reset, 2025 has rewarded investors who combine concentration in their best-underwritten ideas with hard downside protection. The result is not just fewer drawdowns — it is better compounding. Below are working notes on how we practice this discipline across holdings and selective ventures.

1) Concentration is a function of evidence, not enthusiasm

We size positions according to the weight of verified evidence: quality of cash generation, return on incremental capital, durability of advantage, and alignment of incentives. In a higher-cost-of-capital world, spread matters more than stories. Concentration amplifies both outcomes and blind spots; the antidote is a research cadence that continuously tries to falsify our own thesis.

  • 3–6 core positions deliver most of the long-term outcome; peripheral bets are clearly labeled as optionality, not core.
  • Underwrite to downside first: how the business behaves under stress determines true size, not base case IRR.
  • Re-sizing is research: trimming on thesis drift and adding on improving unit economics keeps concentration earned, not inherited.

2) Downside protection is built, not bought

Options and collars can be useful at the margin, but the most reliable protection is structural — balance sheets that self-insure, business models with negative working capital, and managers who allocate to resilience before growth.

  • Prefer self-funding flywheels to growth that depends on external capital cycles.
  • Work capital structure first: refinancing maps, covenants, and liquidity ladders matter more than headline valuation.
  • Operational buffers: variable cost bases, pricing power, and mission-critical products reduce earnings volatility where it counts.
Compounding is not about the highest peaks; it’s about avoiding the deepest valleys.

3) Compounding is a process, not a promise

Valuation is the price of admission; the engine is reinvestment at attractive spreads over time. We favor companies and partners who can consistently redeploy cash at high marginal returns without inflating risk.

  • Cadence over catalysts: quarterly operating habits compound faster than one-time events.
  • Return pathways: buybacks when intrinsic value is demonstrably below price; dividends when opportunity sets narrow.
  • Small, frequent bets: disciplined experimentation improves the opportunity pipeline while capping error cost.

4) Governance and incentives are the hidden duration

In 2025, multiple compression has punished weak governance more than any factor screen. We underwrite governance duration: the probability that rational capital allocation persists through cycles and leadership changes.

  • Clear owner-operator alignment and downside-weighted pay structures.
  • Board quality that adds operating leverage, not just oversight theater.
  • Transparent capital allocation frameworks published and practiced.

5) Practical portfolio construction (how we apply this)

  • Core — Concentrated ownership in 3–6 businesses with durable moats, net cash or sensible leverage, and clear reinvestment lanes.
  • Adjacencies — 5–10 smaller positions or venture-style partnerships that expand the map of future core candidates.
  • Hedges — Situational; used to defend against specific known risks (funding windows, commodity shocks), not to replace underwriting.

Closing thought

Concentration, when earned by evidence and paired with true downside defenses, converts volatility into productivity. Over a decade, that difference dominates. The aim is simple: own fewer, know more, lose less, and reinvest better.
