Separately Managed Account
A separately managed account (SMA) is a portfolio of financial assets managed by a professional investment manager on behalf of a single investor, with the assets held directly in the investor's name (not pooled with other investors' assets) and the investment mandate, guidelines, and restrictions customized to the investor's specific requirements. SMAs provide the benefits of professional management while giving the investor direct ownership, transparency, and tax management flexibility.
Key takeaways
- In an SMA, the investor directly owns all underlying securities—unlike a fund, there is no pooling with other investors, providing transparency, tax-loss harvesting, and customization.
- Hedge fund managers increasingly offer SMA structures (sometimes called 'managed accounts' or 'dedicated funds') to large institutional investors seeking liquidity, transparency, and reduced operational risk relative to commingled funds.
- SMAs typically require higher minimum investments ($5M–$100M+) than equivalent commingled funds, reflecting the cost of bespoke portfolio construction and reporting.
- The investor in an SMA retains custody of their own assets, eliminating the risk of loss due to the manager's insolvency or fraud—a key differentiator from the Madoff-era commingled fund risk.
- Tax efficiency is a major SMA advantage: the investor can harvest losses and manage the timing of realized gains without other investors' trading or redemptions triggering tax events.
Explanation
The separately managed account structure addresses one of the fundamental tensions in professional investment management: the conflict between operational efficiency (pooling assets reduces costs and enables scale) and investor-specific objectives (customization, transparency, and tax efficiency). The SMA resolves this by providing managed portfolio services without commingling—the investor's assets are held in their own account at their chosen custodian, with the manager directing trades but the investor retaining legal ownership of all securities.
In the hedge fund and alternative investment space, institutional investors—large pension funds, sovereign wealth funds, insurance companies, and endowments—have increasingly requested SMA access to hedge fund strategies following the losses and liquidity crises experienced through commingled fund structures during 2008–2009 and 2020. The primary motivations are: transparency (daily position-level visibility versus quarterly reports in commingled funds), liquidity (ability to withdraw on demand or with shorter notice than fund redemption terms), customization (ability to exclude specific securities for ESG, compliance, or risk management reasons), and operational risk reduction (assets are held at the institution's own custodian rather than the manager's prime broker, eliminating risk of manager fraud or insolvency).
From the investment manager's perspective, running SMAs involves substantially greater operational complexity than managing a single commingled fund. Each SMA account has its own investment guidelines, reporting requirements, tax sensitivity, and customization constraints. Orders must be aggregated (blocked) and allocated across all accounts—the fund, multiple SMAs, and potentially multiple share classes—according to a fair and consistent allocation policy (required by the SEC under the Investment Advisers Act). Portfolio construction for an SMA investor with an exclusion list (e.g., no tobacco, no defense contractors, no competitors of the investor) may deviate meaningfully from the model portfolio, creating tracking error relative to the fund.
The pricing of SMA mandates reflects the higher operational cost: management fees are typically the same or slightly higher than commingled fund fees for equivalent strategies, with performance fees structured similarly (20% above a hurdle rate). Some managers charge a 'platform fee' on top of base management fees to cover the incremental administrative cost of dedicated reporting and customization. The minimum AUM thresholds for SMA access vary widely—equity long/short managers may accept SMAs at $25–50M, while complex multi-strategy or illiquid alternative managers may require $100M–$500M to justify the operational build-out.
The post-Madoff regulatory environment significantly increased institutional demand for SMAs. Ponzi schemes and fund-level frauds were facilitated by the commingling of investor assets with manager-controlled accounts—a structural feature that is impossible in a properly structured SMA where assets are held by the investor's custodian. The AIMA (Alternative Investment Management Association) and institutional investor groups (ILPA, PIAC) have developed model SMA terms and minimum operational standards that define best practices for governance, reporting, and valuation in SMA mandates.
Example
A state pension fund with a $50 billion total investment program allocates $500 million to a long/short equity hedge fund strategy. Instead of investing in the manager's commingled fund (which has $3 billion AUM, quarterly redemptions with 60-day notice, and monthly NAV reporting), the pension fund negotiates an SMA structure. Under the SMA: assets are held at the fund's custodian (Northern Trust) in a dedicated account in the pension's name; the manager has trading authority but no custody of assets; daily position transparency is provided to the pension fund's risk team; the investment guidelines exclude tobacco companies (pension board policy) and any company where the pension is also an active shareholder engagement counterpart; liquidity allows 30-day redemption on demand. The pension pays a management fee of 1.5% and a performance fee of 15% above a 5% hurdle. The additional 0.5% management fee (versus the 1.0% available in the commingled fund) compensates the manager for the operational complexity. The pension values the daily transparency, 30-day liquidity, and asset protection highly enough to pay the premium.
