How Family Offices Design Portfolios for 30-Year Outcomes

Описание: What if the easiest alpha in public markets isn’t stock picking… but taxes?

In this episode, I sit down with Zach Wainwright, Founder of Twin Oak ETF Company, to break down structural alpha, ETF tax efficiency, and how high-net-worth investors can compound capital more intelligently. Zach shares lessons from his time at Wellington, TIFF, and inside a single-family office — and why long time horizons, incentive alignment, and tax awareness may be more powerful than traditional stock-picking alpha. We also dive into tail-risk hedging inside an ETF wrapper and how families can design portfolios to survive extreme drawdowns without sacrificing long-term compounding.

Highlights:
Why “long-term” means something different for asset owners vs. traders
Lessons from Wellington, TIFF, and investing in emerging managers
Why fund one through fund three often generate the most alpha
Incentive alignment and GP capital commitments
Structural edges inside single-family offices
The three levers of value creation: security selection, asset allocation, structural alpha
Tax drag in mutual funds vs. ETFs
How ETFs preserve tax alpha through in-kind redemptions
Tail-risk hedging inside an ETF vs. private hedge funds
Avoiding the 10 worst days — and capturing the 10 best
Designing portfolios to reduce maximum drawdown
Why tax deferral may be the most sustainable form of alpha

Guest Bio:
Zach Wainwright founded Twin Oak ETF Company with a singular focus: delivering innovative, institutional-quality, tax-efficient solutions to high-net-worth clients. Throughout his career at firms such as Wellington Management and TIFF, and later within a single-family office, Zach observed that taxable investors were often underserved — losing significant performance to unnecessary tax drag despite strong investment selection.

At Twin Oak, Zach focuses on what he calls “structural alpha” — leveraging time horizon, tax efficiency, and thoughtful implementation to unlock portfolio potential. His approach blends institutional rigor with family-office pragmatism, creating ETF-based solutions that aim to preserve compounding, reduce drawdowns, and optimize after-tax outcomes for long-term investors.
