Diversifying Concentrated Employer Stock

The default trajectory for a long-tenured tech employee: RSUs vest, you hold, stock appreciates, suddenly 40–70% of your net worth is in one ticker that is also your employer. Your salary is exposed to this company. Your retirement is exposed to this company. If the company has a bad decade, so do you.

Most concentrated-stock positions need to come down. The question is how, given that tax basis is often low and sale triggers meaningful capital gains.

Strategy 1: Gradual sell-down (the default)

Sell a fixed percentage of position each quarter — typically 5–10% of current value — over 2–4 years. Dollar-cost-averaging in reverse.

• Pros: simple, predictable tax impact, psychologically easier than selling all at once.
• Cons: slow; if you're still accumulating new RSUs, your position may barely shrink.
• Best for: positions under $5M, employees still working at the company.

Strategy 2: Exchange funds

An exchange fund pools contributions from many concentrated-stock holders. You contribute your shares, you receive partnership units representing a diversified basket. No tax at contribution (it's an exchange, not a sale).

• Pros: instant diversification with no immediate tax hit. Preserves basis for estate-planning step-up.
• Cons: 7-year lockup is standard. Investment is relatively illiquid. Fees are ~1%/year. Minimum contributions usually $1M+.
• Best for: positions $2M+ where immediate diversification matters more than liquidity.

Strategy 3: Direct indexing with tax-loss harvesting

Open a separately-managed account that mimics an S&P 500 or similar index. Fund it over time with sales of concentrated stock. The SMA aggressively harvests tax losses on individual positions, which offset the gains from selling employer stock. Over 3–5 years, you can typically shelter 30–50% of your employer-stock gains via harvested losses.

• Pros: tax-efficient, keeps you invested, works at any position size $500K+.
• Cons: requires an SMA provider (Wealthfront, Parametric, Aperio, others) — typically 0.30–0.40% fee. Harvesting diminishes over time as the portfolio matures.
• Best for: ongoing diversifiers with stable long-term tax brackets.

Strategy 4: Charitable giving via donor-advised fund (DAF) or CRUT

Donate appreciated stock directly to a DAF or charitable remainder unitrust.

• DAF: contribute shares, get full FMV deduction (subject to AGI limits), fund grants to charities over time. Removes the stock from your balance sheet at no tax cost if you were planning to give anyway.
• CRUT (Charitable Remainder Unitrust): contribute stock, receive a defined annual payout for life (5–50% range), remainder goes to charity at your death. Partial current deduction; defers capital gains; useful for very large positions.

• Pros: zero-tax diversification at the margin; maximizes philanthropic impact per dollar given.
• Cons: charitable intent required — this is a philanthropy strategy with tax benefits, not a tax strategy with optional philanthropy.
• Best for: people who were planning to give anyway; high-income years where the deduction is worth more.

Strategy 5: Collar / protective options strategy

Write covered calls at a strike above current price, use the premium to buy protective puts at a strike below current price. Locks in a price range (floor + cap) without selling the underlying.

• Pros: defer sale and potential tax. Get downside protection.
• Cons: caps upside. Options expertise required. IRS "constructive sale" rules can treat aggressive collars as a taxable sale anyway. Not useful for employees of companies where trading is restricted by compliance.
• Best for: non-insider employees with large positions needing short-term price protection (1–2 years) before tax or liquidity events.
