The Hidden Cost of Holding Too Much Company Stock

July 20265 min read

Executives and long-tenured employees often accumulate concentrated positions that feel like loyalty — but carry risks that a diversified portfolio would never accept.

For many executives and long-tenured employees, a concentrated position in company stock is not a deliberate investment decision — it is the accumulated result of years of equity compensation, stock options, and restricted share grants. Over time, a single holding can come to represent 30, 50, or even 70 percent of a household's investable assets. The position feels like loyalty. It often feels like identity. And it carries risks that a thoughtfully constructed portfolio would never accept.

The core problem is that your human capital and your financial capital are already correlated. Your salary, your bonus, your career trajectory, and your retirement benefits are all tied to the same company whose stock dominates your portfolio. If the company struggles, you may face reduced compensation, layoffs, and a declining stock price simultaneously. Diversification exists precisely to protect against this kind of correlated risk — but a concentrated position eliminates it.

The tax dimension makes this genuinely complex. A large concentrated position often carries a very low cost basis, meaning a straightforward sale would trigger a substantial capital gains tax bill. This creates a real tension: the financially rational move (diversify) conflicts with the tax-efficient move (hold). Many investors resolve this tension by holding indefinitely — which is rarely the right answer.

There are several strategies that can reduce concentration while managing the tax impact. A systematic sale program — selling a fixed percentage of the position each year — spreads the tax liability over time and removes emotion from the decision. Exchange funds allow investors to contribute appreciated stock in exchange for a diversified fund interest, deferring the gain. Charitable giving strategies, including donor-advised funds and charitable remainder trusts, can transfer appreciated shares without triggering capital gains while supporting philanthropic goals. Hedging strategies using options can provide downside protection while preserving the position.

The right approach depends on the size of the position, the cost basis, your income, your timeline, and your estate goals. What is rarely the right approach is to do nothing. The cost of inaction — measured in risk, not just taxes — is often far higher than investors realize until it is too late.
