Strategy overview

A covered call is an option strategy in which a trader holds a position on a stock and subsequently sells a call option on the same stock in order to produce supplementary earnings from the asset.   

When you sell a call option, you are obligated to sell the stock you already own at the strike price if the buyer exercises the call option. 

Market outlook

  • Slightly bullish or slightly bearish 

Strategy benefits

  • Receive income from the option premium when you sell call options.
  • Offset losses if your stock depreciates in value.

Strategy downsides

  • May lose your stocks if the stock value rises beyond the strike price of the option.
  • Even if your stock goes up significantly, the upside is capped by the strike price, plus the option premium received.
  • If the stock goes down significantly, the option premium you receive will not be enough to offset your losses.

Buy covered call example


You want to buy 100 shares of ABC stock valued at $45. In the short term (less than 30 days) you expect the stock price to rise slightly to a maximum value of $48. 
You sell a $50 call option on ABC stock that expires in 30 days, which earns you an option premium valued at $100 (1.00 option premium x 100 shares = $100).

Note: one options contract = 100 shares.

This means that the buyer of the call option has the right to purchase the stock at a $50 strike price before the 30-day expiration date.

Possible results

  1. ABC shares go up slightly for the next 30 days, rising to $47.50, but still well below the strike price of $50. The $50 call option expires worthless, and you keep the call option premium ($100), plus you earn an additional $250 because the shares went up $2.50. Your total profit would be $350.

  2. ABC shares drop to $44, meaning the call option expires worthless, and you keep the 
    call option premium ($100). However you lose $1 per share ($1 x 100 = $100) because the share price dropped from $45 to $44. Since the option premium offsets the share depreciation, you break even.

  3. ABC shares rise to $52, slightly above the $50 strike price, meaning the call option is exercised by the buyer. Although your profit upside was capped at $50, you miss out on an additional profit of $200 ($2.00 x 100). Still, this gives you a total profit of $600.

  4. ABC shares drop to $40, well below the strike price, meaning the call option expires worthless. Although you keep the option premium ($100), you incur significant loss owning the shares themselves ($5 x 100 = $500). Your total loss would be $100 (call option premium) - $500 (share depreciation) = -$400.

Profit and loss explained

Maximum profit

Maximum profit = [(strike price – stock purchase price) x number of shares] + (option premium x number of option contracts x number of shares per contract)

Maximum loss

Maximum loss = (stock purchase price x number of shares) – (option premium x number of option contracts x number of shares)

Although you receive a premium when you sell the call option, the most risk comes from owning the shares themselves because the stock may actually drop in value until the option expiry date. 

Break-even at expiration

Break-even point = stock entry price – option premium

Sample calculations

  • Stock value at start of strategy: $45
  • To execute the strategy: sell $50 call option for $100
  • Result: $100 net credit
Stock price at expiration Profit and loss calculations 

$1.00 (option premium)

–  $5.00 (share depreciation)

x 100 (number of shares)

= $400 loss 

$1.00 (option premium)
x 100 (number of shares)

– $1.00 (share price drop)

x 100 (number of shares)

= $0 (break-even)


$1.00 (option premium)

x 100 (number of shares)

= $100 profit 


$1.00 (option premium)

x 100 (number of shares)

+ $3.00 (share appreciation)

x 100 (number of shares)

= $400 profit 

$1.00 (option premium)

x 100 (number of shares) 

 + $5.00 (share appreciation capped at $50 strike)

x 100 (number of shares)

$600 profit
