If you’ve built a successful career at a public company, there’s a good chance a large portion of your net worth is tied up in one place: your company’s stock. Whether through Restricted Stock Units (RSUs), Incentive Stock Options (ISOs), or other plans, this equity has been a powerful engine for building wealth.
But as you approach retirement, that engine of growth becomes a significant source of risk. A life-changing windfall on paper can become a retirement-derailing loss if not handled correctly.
The most important mindset shift is this: Treat your equity compensation as a future paycheck, not as a core investment. Your goal should be to systematically convert this concentrated, high-risk position into a diversified portfolio that is built to fund your retirement.
The Problem: Concentration Risk
We’ve all heard the horror stories of employees who were millionaires one day and wiped out the next because their company’s fortunes reversed. When 30%, 40%, or more of your net worth is in a single stock, you are making an undiversified bet. You are tying your financial future not just to the stock market, but to the performance of one specific company in one specific industry. This is a risk you don’t need to take.
The “When” and “How” of Selling: A Tax-Smart Approach
The challenge isn’t just if you should sell, but how you do it tax-efficiently. Each type of equity has different, complex tax rules.
- Restricted Stock Units (RSUs): When RSUs vest, they are taxed as ordinary income. The key here is to sell them immediately upon vesting. Many employees make the mistake of holding them, which is like taking your cash paycheck and buying only your company’s stock with it. By selling immediately, you lock in the value and avoid further concentration risk. You then use the cash to build a diversified portfolio.
- Incentive Stock Options (ISOs): ISOs are incredibly powerful but also complex. Exercising them doesn’t create regular income tax, but it can trigger the Alternative Minimum Tax (AMT). If you exercise and hold the shares for one year, the entire gain can be taxed at lower, long-term capital gains rates. This requires a multi-year plan to manage the cash flow needed for the exercise and to avoid the AMT trap.
- Non-Qualified Stock Options (NSOs): When you exercise NSOs, the “bargain element” (the difference between the strike price and the market price) is taxed as ordinary income, just like your salary. The decision here involves timing the exercise to manage that income hit, often by spreading it across different tax years.
From a Single Stock to a Secure Retirement
A major liquidity event—like an acquisition or an IPO—or simply approaching retirement is the perfect catalyst to create a plan. This plan should involve:
- Setting a Target: How much is “enough” to keep in company stock? (For most, the answer is no more than 5-10% of their total net worth).
- Creating a Timeline: Systematically selling shares over a set period to manage tax implications.
- Building a Portfolio: Using the proceeds to build a globally diversified, evidence-based portfolio that is aligned with your actual retirement goals.
Your company stock helped you win the game. A smart diversification strategy is how you make sure you keep what you’ve won.
