How can I diversify a concentrated stock position without selling everything at once?
By Adam Kasick | Wealth Advisor | Updated September 2026
Diversification does not have to mean selling the entire position tomorrow. Depending on the account and your circumstances, the plan may involve staged sales, tax-aware rebalancing, charitable gifting, building other assets around the position or other risk-management techniques.
Here's how I'd think about it.
Concentration is not automatically a mistake. It becomes a planning problem when we cannot explain why the position is still the right size, what risk it creates or what would happen to your goals if the asset fell substantially.
Start with the outcome
How much concentration are you comfortable keeping? How much liquidity do you need? What tax bill are we willing to create? Those questions should drive the strategy.
What I would avoid
A complicated strategy whose only purpose is avoiding the emotional discomfort of making a decision. Complexity should solve a real problem.
Here's what I'd want to know about you.
- What percentage of your financial life depends on this asset?
- What is your cost basis and where is the asset held?
- When will you need money from the portfolio?
- What would a major decline change for you?
- What taxes or other constraints would selling create?
I don't want a pie chart to make the decision. I want you to see the tradeoffs clearly enough to make the concentration intentional.
