Public Markets: Equities and Fixed Income

Why Public Markets Anchor the Portfolio

A family office manages far more than investments — payroll, philanthropy, real estate, and estate planning all flow through the same infrastructure. But when a bill comes due, when a capital call arrives from a private fund, or when a family member needs a large distribution, the money has to come from somewhere fast. Public equities and fixed income are that somewhere. They can be converted to cash in days, sometimes hours, which is why practitioners commonly refer to them as the liquid sleeve of the portfolio.

This liquidity function means the public markets allocation isn't simply about returns. It is the shock absorber and the fuel tank for every other activity the family office runs. Understanding how it works — and how families typically structure it — is therefore central to understanding what a family office is and what it actually does day to day.

Equities: The Ownership Layer

Equities are ownership stakes in publicly traded companies. When a family holds equities, they participate in the earnings, growth, and occasional losses of those businesses. Over long time horizons, equities have historically been the primary engine of portfolio growth, though with meaningful short-term volatility.

Families typically access equities through three main structures: index funds or exchange-traded funds (ETFs), actively managed funds, and separately managed accounts (SMAs). Each carries different cost, tax, and control characteristics.

Index Funds and ETFs

An index fund simply tracks a market index — a predefined list of securities such as a broad stock market benchmark — rather than trying to beat it. An ETF (exchange-traded fund) does the same thing but trades on a stock exchange throughout the day like an individual share. Both approaches are often called passive investing because no manager is actively choosing which securities to buy or sell. Costs tend to be lower, and because turnover inside the fund is minimal, taxable distributions are often smaller.

Active Management

Active management means a portfolio manager makes deliberate decisions about which securities to hold, in what weights, and when to buy or sell — with the goal of outperforming a relevant benchmark. Active managers charge higher fees, typically expressed in basis points (one basis point equals one one-hundredth of a percentage point). The central debate between passive and active investing is one of the most discussed topics in institutional investing; families commonly use both, depending on asset class, tax situation, and conviction in a particular manager. The manager selection process is a discipline in its own right.

Separately Managed Accounts

An SMA is a portfolio of individual securities held directly in the family's own account, managed by a professional according to an agreed strategy. Unlike a fund, the family actually owns each underlying stock or bond — which creates meaningful tax flexibility. A family can instruct the manager to sell specific lots, realize losses, or avoid selling a position that carries a very low cost basis (the original purchase price used to calculate a taxable gain). For larger portfolios, SMAs are a common choice precisely because of this control.

Fixed Income: The Stability and Income Layer

Fixed income — bonds and similar instruments — represents loans made by the investor to a government, municipality, or corporation. The borrower promises to pay regular interest and return the principal at a specified maturity date. Because those payments are contractually defined, bonds behave more predictably than equities, which is why they are often used to reduce overall portfolio volatility and provide steady income.

Treasury and Municipal Ladders

A bond ladder is a straightforward concept: a family buys bonds that mature at different future dates — say, one year out, two years out, three years out, and so on — so that a portion of the principal comes back regularly. This creates predictable cash flow without forcing the family to sell bonds at an inopportune time. U.S. Treasury bonds are backed by the federal government and are among the most liquid securities in the world. Municipal bonds (often called "munis") are issued by state and local governments; the interest they pay is often exempt from federal income tax, and sometimes state tax as well. Readers must work with qualified attorneys and CPAs to understand which tax treatment applies to their situation — tax rules change and vary by jurisdiction.

Cash and treasury management connects closely here: the shortest rungs of a ladder — bonds maturing within months — effectively serve as a cash equivalent, bridging the gap between the liquid sleeve and actual operating cash.

Tax-Aware Investing: The Overlay That Matters

Public markets are where tax management is most actively practiced, because the family controls the timing of nearly every transaction. Two concepts appear constantly in this context.

Tax-Loss Harvesting

Tax-loss harvesting means intentionally selling a security that has declined in value to realize a loss on paper, which can offset taxable gains elsewhere in the portfolio. The family (or their manager) typically reinvests the proceeds in a similar — but not identical — security to maintain market exposure. The rules around what counts as "similar" are precise and consequential; working with a qualified CPA is essential. In SMAs especially, managers can harvest losses at the individual security level throughout the year, which is one of the reasons large families often prefer them to funds.

Asset Location

Asset location is the practice of placing different types of investments in the most tax-efficient account type available. For example, assets that generate ordinary income — certain bonds, for instance — might be held in tax-deferred or tax-exempt accounts, while assets expected to produce long-term capital gains might sit in taxable accounts. The goal is to minimize the family's overall tax drag without changing the total asset allocation. Because family offices often manage assets across trusts, entities, and individual accounts simultaneously, asset location decisions can be genuinely complex. Again, readers should work with qualified tax professionals on the specifics.

Active vs. Passive: A Framework, Not a Verdict

The active-versus-passive question is best understood as a spectrum rather than a binary choice. Families commonly blend both approaches, and the mix often depends on the asset class, the available manager talent, and tax considerations.

The Investment Policy Statement — the governing document that defines how the family's capital is managed — typically records which approach applies to which portion of the portfolio and why. That document keeps decision-making consistent when markets are turbulent and managers rotate.

How the Liquid Sleeve Funds Everything Else

Consider a hypothetical three-generation family with two operating businesses and a portfolio that includes private equity, private credit, and real estate alongside public securities. The private investments are largely illiquid — they cannot be sold quickly without penalty or loss. When a private fund sends a capital call (a request for the committed but not yet invested capital), or when the family needs to fund a large charitable pledge, or when an unexpected legal cost arises, the public markets portfolio is typically the first source of funds.

This is why asset allocation decisions about the size of the liquid sleeve are not purely about expected return. They are about maintaining the operational integrity of the entire family office. A family that over-allocates to illiquid private investments and under-maintains its liquid sleeve may find itself forced to sell private assets at the worst possible time — a scenario practitioners call a liquidity squeeze.

Liquidity, concentration, and risk management sit alongside public markets management as companion disciplines. Together, they define how much flexibility a family actually has — regardless of what the total portfolio is worth on paper.

The liquid sleeve is not just a return engine. It is the operating budget, the emergency fund, and the bridge to every illiquid opportunity the family wants to pursue.

Tax-aware management of public securities, structured thoughtfully around the family's broader accounting and reporting infrastructure, is often where a well-run family office earns some of its clearest measurable value — not through exotic strategies, but through the disciplined, consistent application of concepts like harvesting, location, and laddering across many years and market cycles.
