The "Hedged" Bull

A Bull Call Spread (or Vertical Debit Spread) is a strategy where you buy a call option and simultaneously sell a higher strike call option with the same expiration date.

Why sell the second call? To reduce the cost of the trade. By collecting premium on the short leg, you lower your break-even point.

The trade-off: You cap your maximum profit. You are saying, "I think the stock will go up, but I don't think it will go to the moon immediately."

Key Concept: You trade "unlimited upside" for a "lower cost basis" and "higher probability of profit".

Example: The XYZ Spread

Stock XYZ is trading at $32.

1. Buy October 30 Call for $3.00.

2. Sell October 35 Call for $1.00.

Net Debit: $2.00 ($3 - $1).

Instead of paying $300 for the naked call, you pay only $200 for the spread.

Lower Strike (Buy)

$30.00

Higher Strike (Sell)

$35.00

Net Debit (Max Loss)

$2.00

Max Profit

$3.00

The Profit Formula

Max Profit: (Difference in Strikes) - Net Debit.

($35 - $30) - $2 = $3.00.

Max Loss: Net Debit Paid.

$2.00.

Break-even: Lower Strike + Net Debit.

$30 + $2 = $32.

Notice the break-even is exactly where the stock is trading ($32). If you had bought the naked call for $3, your break-even would be $33. The spread starts making money sooner.

The Payoff Diagram

The profit graph looks like a step. It rises and then flattens out at the short strike.

You make money as long as the stock stays above $32. You max out your profit if the stock hits $35.

  • It lowers your cost of entry and your break-even point.
  • Your risk is limited to the Net Debit paid.
  • Your profit is capped at the difference between the strikes minus the debit.
