Personalized Insights
Actionable recommendations based on your numbers
Assignment risk is 15% per cycle
With a 5% out-of-the-money strike price, you have approximately a 15% chance of assignment each cycle. If assigned, shares are sold at the strike price, and you miss further upside. Consider rolling options before expiration to avoid unwanted assignment.
Premiums are taxed as short-term capital gains at 32%
Your $32,445 in annual premiums will generate approximately $22,063 after taxes. Unlike qualified dividends (taxed at 0-20%), options premiums are always taxed at ordinary income rates. Consider writing calls in tax-advantaged accounts (IRA) when possible.
Rolling calls can help manage assignment risk
When a call approaches the strike price near expiration, you can 'roll' it — buying back the current call and selling a new one at a higher strike or later expiration. This costs approximately $25 per contract but helps retain your shares while collecting additional premium.
Implied volatility at 25% supports premium income
Higher implied volatility means richer option premiums. At 25% IV, you are collecting above-average premiums. Consider selling more aggressively during volatility spikes (earnings, market events) for even higher income.
Your portfolio supports 100 covered call contracts
With $500,000 at an average price of $50, you can write up to 100 contracts per cycle. You are writing 20 of 100 available contracts, leaving room to scale up.
Watch for early assignment around ex-dividend dates
With a 2% dividend yield, there is increased risk of early assignment just before ex-dividend dates. The call holder may exercise early to capture the dividend. Consider avoiding writing calls that expire right after ex-dividend dates, or factor the dividend into your premium expectations.
Covered calls add $2,704/month to your retirement income
Combined with $833/month in dividends, your effective monthly income is $3,537. This 8.5% effective yield substantially exceeds the ~4.5% available from investment-grade bonds, making covered calls an attractive income enhancement for retirees comfortable with the strategy.
Trade-off: approximately $150/year in capped upside
When shares are called away, you miss appreciation above the strike price. At 8% expected appreciation and 15% assignment probability, you sacrifice roughly $150/year in potential gains. However, you collect $32,445 in certain premium income — a more predictable cash flow for retirement budgeting.
