Executive compensation packages—particularly those heavy on Restricted Stock Units (RSUs) and Stock Options—are powerful wealth builders.1 However, their very nature creates a massive, often risky, portfolio concentration: a large percentage of your net worth tied to the performance of a single company, your employer.
After 25 years of guiding executives, I know the key to true financial independence is a disciplined, tax-aware strategy to convert that concentrated risk into a diversified, lasting portfolio.
🛑 The Core Challenge: Concentration Risk
The typical executive’s financial exposure is immense: they have their salary, their job security, and their net worth all tied to the success of one company. The goal of diversification is to reduce this single point of failure. A common rule of thumb is to aim for keeping company stock below 10% to 30% of your total portfolio, depending on your risk tolerance and age.
RSUs vs. Stock Options: The Tax Timeline
Understanding the tax trigger is the first step to diversification:
| Equity Type | Taxation Trigger | Initial Tax Rate |
| Restricted Stock Units (RSUs) | Vesting | Ordinary Income Rate |
| Non-Qualified Stock Options (NSOs) | Exercise | Ordinary Income Rate |
| Incentive Stock Options (ISOs) | Sale (potential tax advantages, but triggers AMT) | Capital Gains Rate (if rules met) |
1. RSU Diversification: The “Sell Immediately” Rule
RSUs offer the clearest path to diversification because the tax event happens at vesting, regardless of what you do next.2
The Three-Step Diversification Process
- Stop the Bleeding: As new RSUs vest, sell the additional shares immediately.3 Since the entire value is taxed as ordinary income upon vesting, selling immediately (or the next day) means there’s little to no additional capital gain to report.4 This is the quickest way to stop your concentration from growing.
- Cover Taxes Efficiently: Companies often automatically withhold shares (“sell-to-cover”) to satisfy statutory tax withholdings.5 If the withholding is insufficient, you must have the liquidity to pay the remaining tax liability.6
- Systematically Sell Existing Stock: Develop a plan to sell down the rest of your already-vested, highly concentrated stock over time. Look for years where you have a lower income year or capital loss carry-forwards to maximize tax offsets.
2. Stock Option Strategies: Exercising Control
Stock Options (ISOs and NSOs) give you more control over the timing of the tax event but introduce the risk that the option expires worthless if the stock price doesn’t exceed the strike price.
Strategic Exercise Points
- Non-Qualified Stock Options (NSOs): Since the gain (market price minus strike price) is taxed as ordinary income upon exercise, exercising in a year when your total income is lower can be advantageous.7 Once exercised, the shares should be treated like RSUs: diversify quickly to reduce concentration risk.
- Incentive Stock Options (ISOs): These offer potential for favorable long-term capital gains tax treatment, but they introduce the complexity of the Alternative Minimum Tax (AMT).8 A common strategic mistake is holding ISOs until near expiration; instead, plan tax-aware exercises and sales well in advance.
- The 10b5-1 Plan: If you are considered an “insider” or face company blackout periods, establish a pre-set 10b5-1 trading plan with your fiduciary advisor. This plan sets up automatic sales based on time or price triggers, providing a critical defense against claims of insider trading and enabling systematic diversification.9
3. Advanced Diversification Tools
Beyond simply selling and reinvesting, sophisticated strategies exist to manage large, concentrated positions:
- Donor Advised Funds (DAFs): Gifting highly appreciated stock to a DAF provides an immediate tax deduction (for the full market value, subject to limitations) and allows you to avoid paying capital gains tax on the appreciation, all while funding future charitable giving.10
- Deferred Compensation Plans (DCPs): If your company allows it, you may be able to defer vesting RSUs into a DCP.11 This can defer the income tax and, crucially, sometimes allows you to diversify the RSU unit into other notional investments within the DCP without triggering a current tax liability.12
- Estate Planning for Basis Step-Up: If you are determined to hold highly appreciated stock, holding it until death is the most tax-efficient transfer method for your heirs, as they receive a step-up in cost basis, effectively eliminating the accumulated capital gains tax.13 However, this keeps the concentration risk on your balance sheet and potentially creates an emotional burden for your heirs.
The Fiduciary Bottom Line
Your equity compensation should accelerate your path to financial freedom, not increase your stress. As your fiduciary partner, my role is to integrate these tax-aware decisions into your comprehensive wealth plan, ensuring your diversification strategy is disciplined, systematic, and always aligned with your goals.
