How advisors reduce concentrated single-stock risk without a big tax bill

Full analysis

Holding most of your wealth in one or two stocks — common among company founders, early employees, and executives who received equity — carries risks many investors underestimate. A 2023 research paper cited by Shang Chou of Dishmi Capital, involving Brooklyn Investment Group, New York University, and Yale University, found that 93% of the time, the median 10-year market-adjusted returns for recent top-performing stocks turned negative; stocks in the top 20% of performers over the previous five years lost an average of 17.8% of value over the following decade.

Advisors are now layering several tools to diversify these positions without triggering a large immediate capital-gains tax: exchange funds (a pooled vehicle where you contribute your stock and eventually receive a basket of different equities — but with a seven-year lock-up and no guarantee of what that basket will contain); tax-aware long/short strategies (portfolios that deliberately realize losses to offset gains from the concentrated stock, while maintaining broad market exposure); options-based hedging through flex options or variable-prepaid forward contracts (where a bank hedges your stock and lends you cash); and Section 351 conversions (which let you contribute a concentrated stock position into an ETF without an immediate taxable sale). Each tool has trade-offs — Opportunity Zone funds can miss return targets by double digits, and both Fidelity and Charles Schwab recently restricted advisor access to long/short strategies on their platforms. The right mix depends on your liquidity needs, timeline, and tax situation.
