Strategy overview



A vertical put spread is an option strategy in which a trader buys and sells a short and long put option of the same underlying symbol simultaneously. The put options must have identical expiration dates but different strike prices.


There are two types of vertical put spreads:


Spread type
Description
Bull Used by a trader who thinks the security’s price will rise before the put options expire.
Bear Used by a trader who thinks the security’s price will fall before the put options expire.

To learn more, see Vertical bear put.


Market outlook

  • Slightly bullish

Strategy benefits


  • Limits your total potential risk
  • Offsets the cost of the put option by selling a less expensive put option

Strategy downsides


  • Limits the maximum profit to the initial option premium received if the underlying stock price rises above the short put option strike price.

Vertical bull put example



Scenario

You believe that ABC shares currently trading at $23 will rise moderately, so you buy a $20 long put option for $125 and sell a $27 short put option for $300. You would receive an initial credit of $175.


This strategy means that you:


  • as the buyer of the put option, have the right to sell the shares at $20 before or at the expiration date
and

  • as the seller of the put option, have the obligation to buy the shares at $27 before or at the expiration date, if the option is exercised by the buyer.

Possible results

  1. At expiration, the stock’s price closes at $28, meaning both put options would expire worthless. As a result, you keep the $175 credit as profit.

  2. At expiration, the shares close at $18, meaning both put options expire in the money (i.e. the strike prices are above the price of the underlying stock).

    In this case, both put options would be exercised.  The intrinsic value of the put options would be as follows: $200 for the long call; $900 for the short call. The spread value would be $700, leaving you with a total loss of $525 after the initial $175 credit has been applied.

Profit and loss explained



Maximum profit


  • Maximum profit = option premium received – option premium paid

Maximum loss

  • Maximum loss = strike price of short put – strike price of long put – net option premium received

Break-even at expiration


  • Break-even point = strike price of short put – net option premium received

Sample calculations



  • Stock value at start of strategy: $23
  • To execute the strategy: Buy $20 long put option for $125, Sell $27 short put option for $300
  • Result: $175 net credit
Stock price at expiration Profit and loss calculations 
$18 $27 (short put) - $18 (stock price at expiration )= $9 x 100 (long put intrinsic value)
$20 (long put) - $18 (stock price at expiration) = $2 x 100 (short  put intrinsic value)
= $700 spread
----
$27 (strike price of short put option)
-$20 (strike price of long put option)
= [$7 x 1 option contract x 100 (number of shares) = -$700]
+$175 (total option premium received)
= $525 loss
$28 $3 (short put option premium)
- $1.25 (long put option premium)
x 100 (number of shares)
= $175 profit
