Vertical Spreads — Buying and Selling the Same Clock
The construction
A vertical spread = buy one option, sell another of the SAME type and expiration, different strikes. Bull call spread: buy the lower-strike call, sell the higher-strike call — cheaper than the naked call (the short call's premium offsets), capped profit at (strike width − net debit), capped loss at the debit. The spread TRADES unlimited upside for a dramatically better cost/theta profile.
Why spreads beat naked options for direction
The short leg does three jobs: subsidizes the cost (less premium at risk), pays you theta on the leg you sold (offsetting decay on the leg you bought), and defines everything — max gain, max loss, breakeven are known at entry. A $5-wide call spread for $2 risks $200 to make $300 (1.5:1) with NO theta bleed net-negative if the stock just holds. Directional trading with the lottery-ticket dynamics removed.
The costs
Capped upside (the big winner pays only the width), two commissions and two spreads to cross (wider effective bid-ask), and early-assignment edge cases on the short leg near dividends. And the max-loss structure means sizing is trivial: risk = debit paid — which makes spreads the cleanest way to apply the day-29 formula to options.
What you'll practise
Stock $100. Buy the $100/$110 bull call spread for a $4.00 debit. What are max profit, max loss, and breakeven?
