  Ratio Call Spread Profile Chart  
 

 
Description:

 

This strategy is the opposite of Call Ratio Backspread. Therefore we have unlimited risk and limited reward. The key to this strategy is the ratio between sold leg and bought leg. Think of this strategy as Selling higher strike Naked Call with added security of a Buy Call with lower strike in case if the stock rises. Number of contracts on sold leg has to be bigger than bought leg and both legs are on the same expiration date. Common ratios are 2:1 and 3:2 (3:1 and 4:1 will have more probability ending up in net credit and more risks).

 

We will achieve the maximum profit provided that the stock’s price is between the two strike prices of bought leg and sold leg (or if the stock’s price stays at strike price of bought leg) at the expiration day.

Investment @ Entry = (Premium of Sold Leg x No of Contracts x 100 Shares) + (Premium of Bought Leg x No of Contracts x 100 Shares) = ($2,000) + $4,000 = $2,000

 

Breakeven Point Down= Strike Price of Bought Leg + Net Debit = $35.00 + $0.40 = $35.40


Breakeven Point Up = Strike Price of Sold Leg + (Spread difference – Net Debit) = $37.50 + ($2.50 – $0.40) = $37.50 + $2.10 = $ 39.60
