Lesson 2 of 5
The short straddle seller is hoping for a lack of movement in the price of the underlying shares and is indifferent to direction. It is a fairly pure bet on decreasing volatility, and benefits from decay. A short straddle is created when an investor sells an equal number of calls and puts with the same strike and expiration. It may be used when investors expect a decrease in either implied volatility or in the movement of the price of the underlying equity. Profit is limited to the initial premium received, while loss is potentially unlimited. The direction of the stock does not matter to the straddle buyer as long as the movement up or down from the strike stays within the price received for the straddle. The maximum gain is the cost of the trade and occurs if the stock closes at the strike price. Time decay helps a straddle seller. The combination has two breakeven points equal to the strike price plus the cost of the trade and the strike price minus the cost of the trade. The straddle seller loses money if the underlying price exceeds a range around the strike price beyond the total premium received.

@$35.00 – At all values below the central strike price the put option has intrinsic value, and in this case is worth $12.00 ($50.00 – $38.00 = $12.00). And so the net loss from the trade is the amount of net premium minus the distance between the central strike price and the value of the shares ($10.00 – $12.00 = $2.00).
Shouldn’t the strike price be $38 instead of $35?
