Covered Call or Collar on a Concentrated Dividend-Paying Position
A 61-year-old client holds 25,000 shares of a regulated utility at $52.40, with a $38.10 cost basis; the position is 18% of her net worth. She wants income and downside protection through year-end. Her account is approved for covered calls only; long puts require a separate approval the firm has not granted. The 50-strike call expiring in 60 days trades at $3.10 (delta 0.72, gamma 0.06, theta -0.04, vega 0.11, implied volatility 31%). The 55-strike call is $1.35 (delta 0.41, vega 0.09), and the 45-strike put is $1.10 (delta -0.29, vega 0.10). The stock goes ex-dividend $0.80 in four trading days. Realized volatility is 19%, and the 50-strike call's time value is $0.70. The client asks whether to sell the 50s, sell the 55s, or 'do the collar' she read about. She also asks what happens if the stock drops 15%.
1. Which strategies can the representative implement today, and what are the economics and risks of selling the 50-strike calls?

Only the covered call is presently permitted; the collar requires long-put approval that has not been granted.
Selling 250 contracts of the 50-strike call produces 250 x 100 x $3.10 = $77,500 of premium. If the stock is called at $50, the client receives $1,250,000 plus the $77,500 premium, or $1,327,500, against a current value of $1,310,000. The maximum gain is therefore $17,500, or $0.70 per share. The premium lowers the economic breakeven to $49.30.
A 15% decline takes the stock to $44.54. The share loss is ($52.40 - $44.54) x 25,000 = $196,500; after the $77,500 premium, the net loss is $119,000. The call does not protect against a large decline.
Early assignment is a live issue. The 50-strike call is $2.40 in the money with only $0.70 of time value, and the $0.80 dividend exceeds that time value. A rational holder may exercise just before the ex-date to capture the dividend. If the client is assigned, she delivers shares at $50, keeps the premium, and misses the $0.80 dividend, or $20,000 on 25,000 shares. Assignment is not certain, but the probability is elevated. Theta works for the short call, while gamma risk increases near expiration.
2. Evaluate the 55-strike call and the collar, including approval requirements and Greeks.
Read the worked answer
The 55-strike call would generate 250 x 100 x $1.35 = $33,750 of premium. If assigned, the maximum gain is ($55.00 - $52.40) + $1.35 = $3.95 per share, or $98,750. Its lower delta of 0.41 makes early assignment less likely than with the 50-strike, and it preserves more upside, but it produces less current income.
The collar would buy the 45-strike put for $1.10 and sell the 55-strike call for $1.35, for a net credit of $0.25. Maximum loss is ($52.40 - $45.00) - $0.25 = $7.15 per share, or $178,750 on 25,000 shares. Maximum gain is ($55.00 - $52.40) + $0.25 = $2.85 per share, or $71,250. However, the long put is not approved, so the representative cannot execute the collar today. The firm must first approve the appropriate options level and document the strategy.
The collar's net delta is roughly 1.00 - 0.41 - 0.29 = +0.30, so it reduces equity exposure substantially. Its net vega is close to zero because the short 55 call (vega 0.09) roughly offsets the long 45 put (vega 0.10). The short call earns theta, while the long put pays theta. The 50-strike sale maximizes premium but maximizes assignment risk; the 55-strike sale balances income and upside; the collar best fits the protection request but cannot be used without approval.
3. If implied volatility falls from 31% to 22% immediately after the trade, how do the 50-call and collar positions react? What does that imply for assignment risk?
Read the worked answer
A volatility drop of 9 points reduces the short 50 call's value by roughly 9 x 0.11 = $0.99 per share, or about $24,750 across 250 contracts, a mark-to-market gain for the seller. The long 45 put loses roughly 9 x 0.10 = $0.90 per share, or about $22,500, so the collar's net vega is nearly neutral. The short 55 call in the collar also gains from lower volatility.
The important second-order effect is on early exercise. Lower implied volatility shrinks the 50 call's time value. Before the volatility drop, time value was $0.70 versus a $0.80 dividend; after the drop, time value may fall below $0.70, making early exercise even more attractive to the call holder. The client's assignment risk therefore rises, not falls, even though the short call shows a mark-to-market gain.
The representative should explain that a volatility decline helps the short option position on paper but does not eliminate the obligation to deliver stock. If the client wants to keep the shares and the dividend, rolling the call before the ex-date or buying it back may be preferable, but any roll must be evaluated on its net cost and must remain within approved strategy levels.
