Talk Your Book: After-Tax Alpha

What It Covers

Erkko Etula, CEO of Brooklyn Investment Group (owned by Nuveen), explains how tax-advantaged long-short SMAs work, detailing how leverage ratios from 110/10 to 275/275 generate realized losses of 25–85% of portfolio value in year one to offset capital gains events.

Key Questions Answered

• •Loss generation by leverage tier: A cash-funded 130/30 strategy generates approximately 25% in realized losses in year one, while a 250/150 strategy generates roughly 85% of initial portfolio value in realized losses. Advisors should match leverage level to the client's specific gain offset need rather than defaulting to maximum leverage.
• •Market-neutral beta-zero structure: When a client faces a large taxable event late in the year, running a 275 long / 275 short portfolio eliminates equity market beta entirely, focusing purely on tax alpha generation. This protects against a simultaneous market drawdown while the tax liability remains outstanding, then transitions to target allocation the following year.
• •Tracking error scales linearly with leverage: A 130/30 strategy carries roughly 1.5–2% annual tracking error versus benchmark, meaning two-thirds of years land within that range of index returns. At 250/150, tracking error rises to 7–8%, so clients should prepare for potential two-standard-deviation outcomes of plus or minus 14–16% versus benchmark.
• •Legacy assets as collateral: Clients holding low-basis concentrated stock positions can use those existing holdings as collateral to build the long-short extension around them, removing the need for a cash-funded entry. The extension generates approximately 15% in realized losses in year one without requiring liquidation of the legacy position.
• •Tax deferral exit planning: All harvested losses embed corresponding gains elsewhere in the portfolio, making these pure deferral strategies, not elimination. Advisors should build a gain-neutral deleveraging plan from day one, using subsequent-year harvested losses to gradually reduce leverage rather than unwinding abruptly and triggering a large tax bill.
