Managing Concentrated Positions

Why it is different for executives

A retail investor with 40% in one company has a diversification problem. An executive with 40% in their employer has their portfolio, their salary, and their future compensation in the same bet.

Consider what a bad year at the company actually looks like: the stock falls, unvested RSUs are worth a fraction of grant value, the next grant is sized in dollars but delivered in shares, performance awards miss and pay zero, bonuses are cut — and if it deteriorates, the job itself is at risk, in a labor market that is weakest for your skills at exactly that moment. These are not independent events.

The mechanics that exist

Described neutrally. Which apply depends on insider status, plan documents, holding requirements, and your tax position.

Trading windows and preclearance. Insiders can typically trade only in open windows after earnings, subject to preclearance and blackouts. This alone shrinks the number of days on which anything can happen, which is why unplanned diversification tends not to occur.

Rule 10b5-1 plans. A written plan adopted while not in possession of material nonpublic information, specifying amounts, prices, and dates or a formula, that then executes on its own. Cooling-off periods, certification requirements, restrictions on overlapping plans, and limits on single-trade plans all apply and vary by role. The structural appeal is that it converts a recurring decision into a single one.

Staged selling. Reducing across multiple tax years to manage bracket exposure and the net investment income tax, usually paired with specific-lot identification. Slower, and it leaves you exposed for longer.

Charitable strategies. Gifting long-term appreciated shares to a public charity or donor-advised fund can allow a deduction at fair market value while avoiding recognition of the embedded gain, subject to AGI limitations and carryforward rules. This matters only where charitable intent already exists — the tax treatment is a reason to give in a particular way, not a reason to give.

Exchange funds. Pooled partnerships into which investors contribute concentrated positions and receive an interest in a diversified pool, structured to defer gain recognition. They generally carry a multi-year holding period, an illiquid asset sleeve, investor eligibility requirements, carryover rather than stepped-up basis, and fees well above index funds. They solve the tax problem by trading it for a liquidity problem.

Hedging and monetization structures. Collars, prepaid variable forwards, and borrowing against the position exist. They carry constructive-sale rules, disclosure obligations, counterparty exposure, and company policies that frequently prohibit them outright for insiders.

Net unrealized appreciation. Where employer stock sits inside a 401(k), the NUA election can change the tax character of the appreciation substantially — and it is irreversible once the distribution is done incorrectly. Covered in the rollover guide.

What actually decides it

Not the stock. The rest of the balance sheet.

An executive with a funded pension, a paid-off house, a spouse with independent income, and eight years to retirement can carry concentration that would be reckless for someone with a large mortgage, two tuitions, illiquid private investments, and a plan that depends on the next three grants vesting at current prices. Same company, same position size, entirely different answers.

The analysis we run: what percentage of required lifetime spending is already covered by diversified assets, how much unvested equity is still coming, cost basis and holding periods by lot, liquidity elsewhere, spousal income and its correlation to the same industry, time to retirement, and leverage against any of it.

Then we stress the plan — mark the position down substantially, apply the associated bonus and future-grant reductions at the same time, and see whether required spending still funds. That answer is specific to you, and it is the one that drives the decision.
