Managing Concentrated Stock Positions

When To Use

• Client holds a single equity position exceeding 10-15% of liquid net worth
• Founder/executive approaching lock-up expiration or 10b5-1 plan window
• Triggering event: IPO, secondary offering, M&A closing, or vesting cliff
• Client requests diversification but faces significant embedded capital gains
• Portfolio risk review flags single-name concentration risk
• Estate or charitable planning where appreciated stock is a core asset

Inputs To Gather

• Position details: Ticker, share count, cost basis (lot-level if available), acquisition dates, holding period status (short-term vs. long-term)
• Restriction status: Rule 144 holding periods, lock-up agreements, 10b5-1 plan status, Section 16 insider status, blackout windows [VERIFY with counsel]
• Client profile: Risk tolerance, liquidity needs, time horizon, income tax bracket (federal + state), net investment income tax exposure
• Existing hedges: Outstanding collars, prepaid variable forwards (PVFs), exchange fund commitments, or margin loans against the position
• Tax situation: Current-year realized gains/losses, loss carryforwards, AMT exposure, state of residence [VERIFY state tax treatment for each strategy]
• Estate and philanthropic goals: Charitable intent, generation-skipping objectives, trust structures in place
• Corporate governance: Any contractual or company-policy restrictions on hedging or pledging shares

Workflow

1. Quantify concentration risk

   • Calculate position as % of liquid net worth and total net worth
   • Run downside scenario analysis: -20%, -40%, -60% drawdowns and impact on financial plan
   • Estimate portfolio volatility contribution vs. a diversified benchmark
   • Identify correlation with client's human capital (e.g., tech executive holding tech stock)

2. Assess tax cost of outright sale

   • Compute federal + state capital gains liability per lot
   • Model after-tax proceeds vs. current value
   • Identify high-basis lots eligible for lower-cost liquidation
   • Factor in net investment income tax (3.8%) and any state surcharges [VERIFY current rates]

3. Evaluate diversification strategies

   • Staged open-market sales: Spread across tax years to manage bracket exposure; pair with harvested losses
   • 10b5-1 plan: Appropriate for insiders; establish during open trading window with required cooling-off period [VERIFY SEC Rule 10b5-1 amendments for cooling-off requirements]
   • Exchange funds (swap funds): Contribute concentrated stock into a diversified partnership; requires 7-year lock-up and meeting qualifying asset mix rules under IRC 721(a)/351 [VERIFY fund-specific terms and accredited investor thresholds]
   • Charitable strategies: Donor-advised fund contributions of appreciated shares (up to 30% AGI), charitable remainder trusts (CRTs) for income stream + partial deduction, charitable lead trusts (CLTs) for estate reduction
   • Gifting: Annual exclusion gifts or completed gifts to irrevocable trusts to shift future appreciation; GRATs funded with concentrated stock

4. Evaluate hedging strategies

   • Costless collars (zero-premium): Set protective put floor and covered call cap; no upfront cost but caps upside. Evaluate constructive sale risk under IRC 1259 [VERIFY collar width to avoid constructive sale treatment]
   • Prepaid variable forwards (PVFs): Monetize position while deferring tax recognition; receive upfront cash (typically 75-90% of current value). Assess loan-vs-sale characterization risk [VERIFY with tax counsel]
   • Protective puts: Outright downside protection; premium cost but unlimited upside. Best for shorter-term risk windows (earnings, lock-up expiration)
   • Margin loans / securities-backed lending: Borrow against position for liquidity without triggering a sale; monitor loan-to-value covenants and margin call risk

Output

Produce a Concentrated Position Management Report containing:

• Executive summary: Current concentration level, estimated unrealized gain, key risk metrics, and recommended strategy
• Position profile table: Shares, cost basis by lot, holding period, restriction status, current market value
• Strategy comparison matrix: Each strategy scored on tax efficiency, liquidity, risk reduction, complexity, and cost
• Scenario projections: After-tax wealth outcomes under recommended vs. alternative approaches across market scenarios
• Implementation timeline: Sequenced action items with responsible parties and deadlines
• Risk disclosures: Constructive sale risk, margin call exposure, regulatory filing obligations (Form 4, Form 144), and strategy-specific risks

Quality Checks

• Confirm all cost basis data is lot-level and sourced from custodial records, not client estimates
• Verify insider status and trading restrictions with corporate counsel before recommending any sale or hedge [VERIFY]
• Ensure collar strike prices are wide enough to avoid constructive sale treatment under IRC 1259 [VERIFY with tax advisor]
• Validate that exchange fund qualifies under IRC 721(a) diversification rules and that client meets accredited investor requirements
• Check that charitable contribution deduction calculations use correct AGI limitation (30% for appreciated capital gain property to public charity) [VERIFY for private foundation gifts: 20% AGI limit]
• Confirm PVF terms do not trigger current income recognition under IRS prepaid forward guidance
• Stress test all margin/lending scenarios at 40-50% drawdown to confirm client can meet margin calls without forced liquidation
• Flag any state-specific tax treatment differences (e.g., California sources gains based on residency at time of sale) [VERIFY state rules]
