Section 5.3 โ Breakeven, Max Gain, & Max Loss
โ๏ธ How Option Value Moves
Call Options increase in value as the underlying security price rises.
Put Options increase in value as the underlying security price falls.
1. ๐ Call Options (XP + Pr = BE):
๐ก Breakeven (BE) Formula for Call
Strike Price (XP) + Premium (Pr) = Breakeven
Long (Buyer) Call: Profits when stock rises above BE
Short (Seller) Call: Profits when stock stays below BE
Example:
Long 1 ABC Jan 50 Call @ 3
โ BE = 50 + 3 = $53
โ Profit if stock rises above $53
๐งฎ On a per-share basis:
Each contract = 100 shares.
So if the premium = $3 โ $300 total.
๐ฐ Maximum Gain and Loss for Calls
Position / Max Gain / Max Loss / Profit when..
Long Call (Buyer) / Unlimited / Premium Paid / Stock price โ above BE
Short Call (Seller) / Premium Received / Unlimited / Stock price โ below BE
Examples:
Long 1 ABC Jan 50 Call @ 3
โ Max Gain = Unlimited
โ Max Loss = $300Short 1 ABC Jan 50 Call @ 3
โ Max Gain = $300
โ Max Loss = Unlimited
Reason:
Stock price can rise infinitely (unlimited upside for long call, unlimited risk for short call).
2. ๐ Put Options (XP โ Pr = BE):
๐ก Breakeven (BE) Formula for Puts
Strike Price (XP) โ Premium (Pr) = Breakeven
Long (Buyer) Put: Profits when stock falls below BE
Short (Seller) Put: Profits when stock stays above BE
Example:
Long 1 ABC Jan 50 Put @ 3
โ BE = 50 โ 3 = $47
โ Profit if stock drops below $47
๐ฐ Maximum Gain and Loss for Puts
Position / Max Gain / Max Loss / Profit when..
Long Put (Buyer) / From BE to $0 (max $47) / Premium Paid / Stock price โ below BE
Short Put (Seller) / Premium Received / Strike Price โ Premium / Stock price โ above BE
Examples:
Long 1 ABC Jan 50 Put @ 3
โ Max Gain = $47 ร 100 = $4,700 (if stock drops to $0)
โ Max Loss = $300Short 1 ABC Jan 50 Put @ 3
โ Max Gain = $300
โ Max Loss = $47 ร 100 = $4,700 (if stock drops to $0)
