Concentrated Stock Positions: 3 Tax-Aware Strategies Chicago Executives Should Understand
For many executives, a concentrated stock position represents years—even decades—of hard work. Restricted stock units (RSUs), stock options, employee stock purchase plans, or founder shares can create substantial wealth. They can also create significant portfolio risk if one company represents a large percentage of an investor’s net worth.
For executives and business owners in Chicago, Barrington, Oak Park, Glenview, and throughout the North Shore, managing concentrated stock positions is often less about deciding whether to sell and more about determining how to diversify in a tax-aware manner while aligning with long-term financial goals.
While every investor’s circumstances are different, there are several planning techniques that may help reduce concentration risk while considering taxes, liquidity needs, estate planning objectives, and charitable goals.
Why Concentrated Stock Can Increase Portfolio Risk
A concentrated position can create significant exposure to company-specific events that are difficult to predict, including:
- Earnings disappointments
- Regulatory changes
- Competitive pressures
- Executive turnover
- Industry disruption
- Changes in investor sentiment
Although many executives understandably have confidence in their employer, modern portfolio theory generally recognizes that uncompensated concentration risk can increase portfolio volatility.
One of the most common questions we receive from executives throughout the Chicago area is:
“How can I diversify without creating a large tax bill?”
The answer depends on numerous factors, including cost basis, tax bracket, liquidity needs, charitable intentions, estate objectives, and insider trading restrictions.
1. Systematic Diversification and Tax-Aware Portfolio Management

For many investors, diversifying gradually over multiple years may be one approach worth evaluating.
Rather than selling an entire position at once, some investors choose to implement a systematic selling strategy designed around:
- projected income
- capital gains exposure
- cash flow needs
- long-term investment objectives
- scheduled tax law changes
This approach may help spread taxable gains over multiple years while allowing the portfolio to become more diversified over time.
Tax-Loss Harvesting
Tax-loss harvesting may also play a role. Realized capital losses elsewhere in a portfolio may be used, subject to IRS rules, to offset realized capital gains generated from selling appreciated securities.
Because tax-loss harvesting involves numerous IRS rules—including wash sale considerations—it should be coordinated with qualified tax professionals.

Rule 10b5-1 Trading Plans
Corporate insiders often face additional restrictions when selling company stock. A properly established Rule 10b5-1 trading plan can allow eligible insiders to establish predetermined trading instructions during an open trading window, subject to SEC requirements.
Whether a 10b5-1 plan is appropriate depends upon an executive’s specific circumstances and should be discussed with legal counsel.
2. Exchange Funds: Diversification Without Immediately Selling Shares
Executives with highly appreciated stock sometimes explore exchange funds, also known as swap funds. Exchange funds allow qualified investors to contribute appreciated securities into a partnership that owns a diversified portfolio of stocks. In exchange, investors receive an ownership interest in the partnership rather than immediately selling their shares.
Potential benefits may include:
- increased diversification
- continued market exposure
- deferral of capital gains taxes under certain circumstances
However, exchange funds also have important limitations, including:
- lengthy holding periods
- limited liquidity
- concentration requirements
- accredited investor eligibility
- manager selection risk
Exchange funds are complex investment vehicles and are not appropriate for every investor.

3. Equity Collars and Charitable Planning Strategies
Some investors wish to reduce downside risk without immediately liquidating their position. Depending upon the facts and circumstances, two strategies sometimes considered are equity collars and Charitable Remainder Trusts (CRTs).
Equity Collars
An equity collar generally combines purchasing a protective put option and selling a covered call option. The objective is to reduce downside exposure while helping offset the cost of the protective put.
Like any options strategy, collars involve tradeoffs.
Potential advantages may include:
- downside protection
- reduced portfolio volatility
- flexibility around future diversification decisions
Potential disadvantages include:
- limited upside participation
- options costs
- tax considerations
- complexity
Whether an options strategy creates unintended tax consequences depends upon how it is structured and should be reviewed by qualified tax and legal professionals.
Charitable Remainder Trusts (CRTs)
For charitably inclined investors, a Charitable Remainder Trust may provide an opportunity to integrate tax planning, income planning, and philanthropic objectives.
Depending on the circumstances, a CRT may provide:
- potential diversification opportunities
- a lifetime or term income stream
- a charitable income tax deduction
- support for charitable organizations
CRTs involve significant legal, tax, administrative, and investment considerations and should be evaluated with an attorney and tax advisor.
Coordinating the Strategy
Successfully managing a concentrated stock position often requires collaboration among several professionals, including a financial advisor, CPA, estate planning attorney, and corporate counsel (when applicable).

Frequently Asked Questions
What is considered a concentrated stock position?
There is no universal definition. Many investment professionals begin evaluating concentration risk once a single security represents approximately 10% to 20% of an investment portfolio, although appropriate concentration levels vary based on an investor’s financial situation and risk tolerance.
Should I sell all of my company stock at once?
Not necessarily. Some investors diversify immediately, while others implement a staged approach over multiple years. The appropriate strategy depends upon taxes, liquidity needs, investment objectives, insider restrictions, and overall financial planning considerations.
Can tax-loss harvesting reduce taxes when selling concentrated stock?
Potentially. Realized capital losses may offset realized capital gains, subject to IRS rules and limitations. Investors should consult their tax advisor before implementing any tax strategy.
What is an Exchange Fund?
An Exchange Fund is an investment partnership that allows eligible investors to contribute appreciated securities in exchange for an ownership interest in a diversified portfolio, generally without immediately recognizing taxable gains. These investments have significant eligibility requirements, liquidity restrictions, and holding periods.
Can options reduce risk on concentrated stock?
Certain options strategies, including equity collars, may reduce downside risk while limiting potential upside. Options involve substantial risks and may not be appropriate for all investors.
