The Advisor’s Guide to Long / Short Tax Strategies
In this episode of Advisor Wars, hosts Bob Huebscher (founder of Advisor Perspectives) and Joe Halpern (Managing Partner and CIO of Obsidian CIO) continue their series on the role of tax planning in the advisory profession.
This time they go deep on one of the more sophisticated and misunderstood tools available to RIAs: long/short overlay strategies for concentrated stock positions.
Joining them is Brent Sullivan, founder of Tax Alpha Insider [https://www.taxalphainsider.com/] and a leading consultant to family offices and ultra-high-net-worth individuals on advanced tax management. Brent brings a rare engineering mindset to tax strategy and his precision shows.
Concentrated stock positions are one of the most common, and most expensive, planning challenges for wealthy clients. The stakes are enormous, and the solutions go far beyond simply selling and paying the tax.
Advisors who understand the full toolkit, including long/short overlays, exchange funds, Section 351 ETF contributions, and direct indexing, will be positioned to deliver far greater after-tax outcomes for their clients.
Key takeaways for advisors:
* Long/short is an alpha strategy first: The tax benefits are real, but they're the gravy, not the potato. Advisors who lead with tax and ignore alpha generation are missing the mark entirely.
* The fishing net analogy: Direct indexing gives you $1 of harvesting surface for every $1 invested. Long/short can expand that to $3, $5, or more, dramatically widening the opportunity set for tax loss harvesting.
* Short positions are a different beast: Unlimited risk, squeeze dynamics, lender recalls, and asymmetric custodian power make short exposure unlike anything in a traditional long-only portfolio. Advisors must understand this before recommending it.
* Manager selection is everything: The RIA's job is rigorous due diligence, on alpha generation, risk management, operational competency, and short-position expertise. Picking the wrong manager is the most common mistake.
* Jurisdiction matters: State tax regimes, like Washington State's unique capital gains structure, can significantly affect whether long/short is the right solution — or whether an exchange fund or options overlay makes more sense.
* Flexibility is the long/short advantage: Unlike exchange funds or Section 351 contributions, long/short is fully customizable at the household level, allowing for liquidity access, tailored sector hedges, and even the ability to maintain some exposure to the concentrated position.
* Costs are real and substantial: Manager fees, financing costs, and trading friction mean that alpha must be present and meaningful — not assumed.
* Know your client's complexity tolerance: Some clients want to understand every layer of the strategy; others want to trust and delegate. The advisor's job is to map the solution to both the financial and psychological profile of the client.
Long/short strategies are growing and as more managers enter the space and custodial lending infrastructure matures, they will become an increasingly important tool for advisors serving high-net-worth clients.
