If a large portion of your net worth is tied to a single stock—perhaps from employer equity, a long-held investment, or an inheritance—you’re not alone. I hear the mix of emotions that can come with this: pride in what that holding represents, gratitude for gains, and a very real concern about “what happens if something goes wrong.”
A concentrated position can create opportunity, but it can also introduce a level of risk that doesn’t always show up until markets get bumpy—or until a life transition (retirement, a business sale, a spouse’s passing) makes the stakes feel higher.
Below are several planning strategies that may help manage concentrated-stock risk in a thoughtful, tax-aware way. The right approach depends on your goals, time horizon, liquidity needs, tax situation, and any restrictions on selling.
1) Start with the “why” and the guardrails
Before talking tactics, it helps to define what you want this stock to do for you.
- Lifestyle protection: How much of your retirement spending depends on this position?
- Legacy goals: Are you hoping to leave the shares to heirs or charities?
- Liquidity needs: Do you need cash for a home purchase, taxes, or upcoming required distributions?
- Risk tolerance: If the stock fell 30%–50%, would it change your plans—or your sleep?
A useful first step is a simple risk audit: What percentage of your investable assets is in the stock? How correlated is it with your job (if it’s employer stock)? How volatile has it been historically? Then you can build guardrails—like a maximum target percentage over time.
2) Build a staged diversification plan (rather than one big decision)
For many families, the challenge isn’t knowing diversification is “good”—it’s the fear of selling too soon, paying taxes, or regretting the timing.
A staged approach can help reduce the pressure:
- Set a schedule: For example, selling a specific dollar amount or percentage quarterly.
- Use price/percentage triggers: Trim when the position exceeds a set percentage of the portfolio.
- Coordinate with tax years: Spreading sales across multiple years may help manage tax brackets.
This is less about predicting the market and more about creating a process you can stick with. A diversified portfolio does not assure a profit or protect against loss in a declining market.
3) Be intentional about taxes (because taxes can drive behavior)
Taxes are often the number-one reason people delay action. Planning can help you avoid letting the tax tail wag the dog.
Key considerations to review with your tax professional:
- Cost basis and holding period: Long-term vs. short-term capital gains treatment.
- Net Investment Income Tax (NIIT): Higher-income households may face additional tax.
- Capital loss harvesting: Using losses elsewhere in the portfolio may help offset gains.
- Charitable giving strategies: Donating appreciated shares can sometimes reduce capital gains exposure while supporting causes you care about.
Tax strategy doesn’t eliminate risk—but it can make diversification feel more practical and less painful.
4) Use charitable giving to reduce concentration and support your values
If philanthropy is important to you, concentrated stock can be a powerful funding source.
Options to discuss with your advisor and tax professional:
- Donate appreciated shares directly to a charity: You may avoid realizing capital gains while potentially claiming a charitable deduction (subject to IRS rules and limitations).
- Donor-advised fund (DAF): You can contribute shares in one year (potentially capturing a deduction) and then grant to charities over time.
- Charitable remainder trust (CRT): In some cases, a CRT can diversify an appreciated position inside the trust and provide an income stream, with complex tradeoffs and costs.
For retirees, this can also pair well with required minimum distribution (RMD) planning in certain situations (e.g., qualified charitable distributions for eligible individuals, when appropriate). Generally, a donor advised fund is a separately identified fund or account that is maintained and operated by a section 501(c)(3) organization, which is called a sponsoring organization. Each account is composed of contributions made by individual donors. Once the donor makes the contribution, the organization has legal control over it. However, the donor, or the donor's representative, retains advisory privileges with respect to the distribution of funds and the investment of assets in the account. Donors take a tax deduction for all contributions at the time they are made, even though the money may not be dispersed to a charity until much later.
Charitable Remainder Trusts: Such trusts are used to develop a vehicle for donations to a favorite charity, which also allows for the reduction of income taxes through a charitable deduction and favorable tax treatment at the date of the gift by non-recognition of built-in capital gains. The use of trusts involves a complex web of tax rules and regulations. You should consider the counsel of an experienced estate planning professional before implementing such strategies.
5) Consider hedging strategies (with eyes wide open)
Some investors want to reduce downside risk without selling immediately. Hedging may be possible, but it brings costs, complexity, and tradeoffs.
Common approaches (not always suitable for everyone):
- Protective puts: Buying put options may help limit downside, but premiums can be expensive.
- Collars: Combining a put purchase with selling a call can reduce the cost of protection, but may cap upside.
- Prepaid variable forwards: In certain cases, these can provide liquidity and downside protection with complex tax and counterparty considerations.
Hedging is not “free insurance.” It may reduce risk in some scenarios, but it can also limit gains, create ongoing costs, and introduce additional risks. Options are not suitable for all investors.
6) Explore exchange funds (for eligible investors)
An exchange fund (available only to certain qualified investors and typically with high minimums and long lockups) can allow you to contribute a concentrated position to a pooled vehicle and receive exposure to a diversified basket.
Important caveats include:
- Limited availability and eligibility requirements
- Lockup periods (often years)
- Fees and liquidity constraints
- Concentrations may still exist inside the fund
This is a specialized tool, but it can be worth exploring when the position is large and the tax friction of selling is high. Exchange funds are privately held funds that can help you diversify a concentrated stock position without realizing capital gains. Alternative investments are investment products other than the traditional investments of stocks, bonds, mutual funds, or ETFs. Examples of alternative investments are limited partnerships, limited liability companies, real estate, and promissory notes. Each customer is responsible for reviewing the terms of all offering and disclosure documents and agreements associated with any alternative investment and determining the appropriateness of any alternative investment chosen, including the description of risk factors contained in the Memorandum prior to making a decision to invest. Some of the risks associated with alternative investments are:
- Alternative investments may be relatively illiquid, and there is no guarantee on the timing or amount of any dividends or distributions.
- It may be difficult to determine the current market value of the asset.
- There may be limited historical risk and return data.
- A high degree of investment analysis may be required before buying.
- Costs of purchase and sale may be relatively high
7) If it’s employer stock, review rules and restrictions carefully
Employer equity can come with additional layers:
- Trading windows/blackout periods
- Insider or affiliate restrictions
- Rule 10b5-1 trading plans (for eligible insiders)
- Employee stock purchase plans (ESPP), RSUs, ISOs/NQSOs and the tax details of each
In these cases, coordination between your financial advisor, tax professional, and legal/compliance resources can be especially valuable.
8) Align the “replacement portfolio” with your retirement plan
When you reduce a concentrated position, the next question is: What do we diversify into?
The goal isn’t to swap one risk for another—it’s to build a portfolio that supports your plan, which may include:
- A diversified mix of stocks across sectors and regions
- High-quality bonds or cash reserves for near-term spending needs
- A rebalancing approach to manage risk over time
For pre-retirees, this often means thinking in “time buckets” (next 1–3 years of spending vs. long-term growth needs). For retirees, it may mean ensuring the portfolio can support distributions through different market cycles.
Bringing it together: progress over perfection
A concentrated stock position is rarely just a math problem—it’s personal. The best strategy is usually the one that balances risk, taxes, and your values in a way you can live with.
If you’re carrying a large single-stock exposure, a good next step is to outline (1) your target level of concentration, (2) a tax-aware timeline, and (3) the specific tools that fit your situation. From there, you can move forward steadily—without feeling like you have to get every decision “perfect” all at once.
