Managed Accounts vs Commingled Funds

The difference between owning a slice of a shared pool of assets and owning a segregated account that just happens to follow the same trading strategy.

Prerequisites: What a Fund Is: Pooled Investment Vehicles

When you invest in a typical hedge fund, your money joins everyone else's in a single commingled pool: the fund owns one portfolio of positions, and your investment is represented by a number of shares or units that entitle you to your proportional slice of that shared pool's value. You don't own any specific stock or bond directly — you own a claim on the fund, and the fund owns the actual securities. This is simple to administer and lets the manager trade one consolidated book regardless of how many investors are involved.

A managed account flips that around. Instead of buying shares in a commingled vehicle, the investor sets up their own separate legal account — still traded by the same manager, following the same strategy — but the securities are held directly in that investor's name, in an account only they own. The manager is granted trading authority over the account rather than commingling the money with anyone else's. Nothing about the day-to-day trading necessarily looks different, but the ownership structure is fundamentally different: the investor has direct title to the underlying assets, full transparency into every position and trade, and the ability to impose their own restrictions (excluding certain securities, setting leverage caps) that wouldn't apply to other investors in a shared fund.

The tradeoffs run in both directions. A managed account gives an investor better transparency, control, and — critically — the ability to walk away with their actual assets in hand if the manager or the relationship goes bad, rather than being one redemption request in a queue behind other investors during a fund-level crisis. Against that, managed accounts are typically only available to large investors because they require the manager to run what is essentially a separate, customized account rather than benefiting from the operational simplicity of one pooled vehicle, and the minimum investment sizes and operational overhead are correspondingly higher.

In a commingled fund you own shares in a shared pool of assets; in a managed account you own the underlying assets directly in your own name while the manager just trades them — a structural difference that mainly matters for transparency, control, and what happens to you specifically if the manager runs into trouble.

The fastest way to tell them apart in practice: in a managed account, ask "whose name is on the brokerage statement for these securities?" If it's the investor's own name, it's a managed account; if it's the fund's name, it's commingled.
