Concentrated Stock Position Management for CFA Level III

Updated 8 October 2026 · Fact-checked

A concentrated position is a single asset that is a large share of a client's wealth. It adds idiosyncratic risk that is not rewarded. You solve questions by matching a strategy (sell, hedge, monetize, diversify, gift) to the client's objectives, taxes, liquidity, legal limits and emotional attachment.

Understand Concentrated Wealth and Single-Asset Positions

A concentrated position is a holding in one stock, one asset or one business that is so large it dominates the client's balance sheet. It often comes from employment (stock awards), a founder's equity, or an inheritance. The client may know the company well and feel loyal to it. That feeling is a behavioral bias, not a reason to hold.

The main problem is idiosyncratic risk. Markets reward systematic risk, not risk that can be diversified away. A single stock can fall sharply on company news, fraud or industry change. If the client also works for the company, a fall hits human capital and financial capital together. This is a correlation problem on the economic balance sheet.

Selling is the simplest fix, but it can trigger large capital gains tax, especially when the cost basis is low. There can also be legal limits. Insiders may face blackout windows, lock-ups, Rule 144-type restrictions on affiliates, and insider trading rules. Some clients also have control or emotional reasons to keep the shares.

So the advisor chooses among strategies. Sell outright (maximum diversification, tax cost now). Hedge with derivatives (cut downside, keep ownership, defer tax). Monetize by borrowing against the shares (liquidity without a sale). Diversify with a staged sale or an exchange fund. Gift shares to family or charity (transfer, tax benefits depend on the jurisdiction). Every choice is judged against the IPS: return objective, risk tolerance, liquidity, time horizon, tax, legal and unique circumstances.

Key rules to remember

Tax cost of selling: Tax = (Sale price − Cost basis) × Capital gains tax rate × Number of shares; Compare this with the risk reduction gained. Use the after-tax proceeds to reinvest.
Zero-cost collar: Long protective put (strike X_put) + short covered call (strike X_call), with premiums offsetting; Floor at X_put, cap at X_call. The client keeps dividends and ownership but gives up gains above the cap.
Collar payoff range: Value at expiry = max(X_put, min(S_T, X_call)) per share; Ignores premium if the collar is zero-cost. Add or subtract any net premium.
Prepaid variable forward (PVF): Upfront cash = a percentage of current value; at settlement deliver a variable number of shares depending on S_T relative to floor and cap prices; Works like a collar plus a loan. Client receives cash now and defers the sale.
Equity swap (hedge): Client pays the stock total return, receives a fixed or floating rate; Gives economic exit without selling. Tax treatment may be treated as a constructive sale, depending on the jurisdiction.
Exchange fund idea: Contribute shares → receive a pro rata share of a diversified pool; Usually has a lock-up period and minimum holding. Defers the gain and diversifies.

How to solve Concentrated Wealth and Single-Asset Positions questions

Use the same sequence for any concentrated position question. Tie every point to the client's facts.

1Identify the position: size as a share of net worth, correlation with the client's job or business, and any employer link.
2List the client's objectives and constraints: risk tolerance, liquidity needs, time horizon, tax basis and rate, legal limits, and preferences such as control or loyalty.
3State the risks of staying concentrated: idiosyncratic risk, no diversification, human and financial capital in the same company, and behavioral bias.
4Rule in or out each strategy: sell, staged sale, hedge, monetize, exchange fund, gift or charity, using the constraints.
5Check mechanics: which instrument gives the floor and cap, what is given up, whether it is a constructive sale, and what the tax result is.
6Recommend one strategy or a combination in line with the command word, and give the reason in one or two sentences.
7Add implementation points: staging over time, reinvestment into a diversified portfolio, and legal and tax review.

Quickest way: Constraint-first shortcut

When to use it: Use this when you have about three minutes on an item set question asking which strategy suits a client.

Circle the one constraint that dominates: low basis and high tax, insider or legal restriction, need for cash, or strong wish to keep the shares.
Low tax pain and willing to sell: sell or staged sale.
Wants to keep ownership and cut downside: collar or put.
Needs cash but will not sell: PVF or margin or share-backed loan.
Wants diversification and defer tax: exchange fund.
Charitable or family transfer intent: if the jurisdiction's tax rules exempt gifted gains or give a deduction, gift low-basis shares and keep high-basis shares to sell. Check those rules first.
Eliminate the options that break the dominant constraint, then pick the best match.

Common mistakes in Concentrated Wealth and Single-Asset Positions

Recommending a full sale without mentioning the tax cost.
Diversification feels like the obvious answer, so the tax trade-off is skipped.
Fix: State the tax cost, then say why sale is still acceptable or why a staged sale or hedge is better.
Saying a collar removes all risk.
The put is remembered but the loss of upside and the floor level are forgotten.
Fix: Say the collar limits loss only below the put strike and caps gains above the call strike. The client still bears loss down to the floor.
Ignoring the client's job link to the company.
Students look only at the investment portfolio.
Fix: Look at the whole balance sheet. If wages, bonuses and shares depend on one firm, risk is higher and diversification matters more.
Suggesting hedging or selling by an insider without noting legal limits.
The legal constraint is treated as a side issue.
Fix: Name the restriction, such as blackout periods, lock-ups or affiliate rules, and say compliance and counsel must clear any trade.
Treating all hedges as tax-free deferral.
Students remember that hedging does not sell the shares.
Fix: Say the tax result depends on jurisdiction and structure. Some hedges are treated as a constructive sale and trigger tax.
Gifting high-basis shares to charity.
Students forget basis matters.
Fix: Where the jurisdiction's tax rules avoid tax on the gain of gifted shares or allow a deduction, give the lowest-basis shares to charity and sell or keep the high-basis shares. The benefit depends on local rules, so state that assumption.

Worked examples

Example 1

A client holds 10,000 shares of her employer's stock worth 80 each (total 8,00,000). Her cost basis is 20 per share and the capital gains tax rate is 20%. She plans to sell all shares and reinvest in a diversified portfolio. Calculate the tax due and the after-tax proceeds.

Show the solution

Gain per share = 80 − 20 = 60.
Total gain = 60 × 10,000 = 6,00,000.
Tax = 6,00,000 × 20% = 1,20,000.
After-tax proceeds = 8,00,000 − 1,20,000 = 6,80,000.

Answer: Tax due is 1,20,000 and after-tax proceeds available to reinvest are 6,80,000.

Example 2

A client owns a stock at 100 and buys a 90 put and sells a 115 call, both expiring in one year, with equal premiums. Ignoring dividends, what is the value per share of the stock plus collar at expiry if the stock price is 70, 100 and 130?

Show the solution

Use value = max(90, min(S_T, 115)) since premiums offset.
At S_T = 70: min(70, 115) = 70; max(90, 70) = 90. Put pays 20, so the position is worth 90.
At S_T = 100: min(100, 115) = 100; max(90, 100) = 100. Neither option is exercised.
At S_T = 130: min(130, 115) = 115; max(90, 115) = 115. The call is exercised and the gain is capped.

Answer: The position is worth 90 at a price of 70, 100 at a price of 100, and 115 at a price of 130.

Exam tips

Read the command word. 'Justify' needs a reason tied to the client, 'calculate' needs a clean number, 'recommend' needs one clear choice.
For strategy choice questions, quote the client fact that drives your answer, such as low basis, insider status or liquidity need.
Know what each tool gives up: collars cap upside, PVFs defer but do not remove the position, exchange funds lock the money up, and sales trigger tax.
Show the collar payoff as a floor and a cap. A simple range answer earns points quickly.
Mention behavioral bias (loyalty, endowment effect, overconfidence) when the vignette shows emotional attachment.

Concentrated Wealth and Single-Asset Positions: frequently asked questions

What is a concentrated position in CFA Level III?

It is a single asset, usually one stock, that makes up a large share of the client's wealth. It carries idiosyncratic risk that the market does not reward. The exam asks you to manage this risk using the client's objectives and constraints.

How does a zero-cost collar work?

The client buys a put for downside protection and sells a call to pay for it. The put sets a floor and the call sets a cap, so the stock value stays within a range at expiry. The client keeps ownership and dividends but gives up gains above the call strike.

What is a prepaid variable forward?

It is a contract where the client receives cash now, a percentage of the stock's value, and agrees to deliver a variable number of shares later. The number depends on the share price at settlement relative to a floor and cap. It gives liquidity and downside protection while deferring a sale.

When is an exchange fund suitable?

It suits a client with a low-basis stock who wants diversification without paying tax now. The client contributes shares to a pool and receives a share of a diversified portfolio. It usually has a lock-up period, so it does not suit someone needing liquidity soon.
