A covered call means you own 100 shares of an underlying (say Meridian Utilities at $72) and sell one out-of-the-money call, such as the $78 strike expiring in 45 days for a $1.40 premium. You pocket $140 per contract immediately. If Meridian closes below $78 at expiration, the call expires worthless and you keep the premium, effectively lowering your cost basis from $72 to $70.60. If it closes above $78, your shares are called away at $78, giving a capped profit of ($78 - $72 + $1.40) = $7.40 per share. The trade-off is clear: you exchange unlimited upside for premium income. Break-even on the downside improves to $70.60, but the stock can still fall well below that.

Key CFA Level II points: the position is equivalent to a short put (synthetic), so the payoff is identical. Choose strikes based on delta — a 0.30 delta call gives roughly a 70% probability of expiring worthless. Avoid writing calls through ex-dividend dates if early assignment risk is high, especially when the extrinsic value is less than the dividend. Income investors often repeat this monthly, targeting 1-2% per month, but in strong bull markets the strategy materially underperforms buy-and-hold.
