If I were to buy a put option with a fifty dollar exercise price and if I were to buy it for $10.00, then the value of my position the payoff for that put option, at the maturity or at the expiration I should say.발음듣기
대기중
Depending on what the stock price is, and expiration would look like this: if the stock price is worth, if the stock price goes to zero then the put option is worth fifty because I could buy the stock at zero and exercise my option to sell at fifty.발음듣기
대기중
All the way to if the stock becomes worth fifty then my put option, I wouldn't need to exercise it because why would I?발음듣기
대기중
It's worthless to have the option to sell something at fifty where you can just sell the actual stock in the open market or buy the stock at fifty.발음듣기
대기중
So if the stock is worth zero, the put option is worth $50, but I spent $10 dollars to get it, so the profit is going to be $40 dollars.발음듣기
대기중
And so then at $50, I wouldn't exercise the put option so I've lost the $10 dollars I spent on the option so my payoff diagram would look like, I'm gonna draw it, relatively neatly.발음듣기
대기중
My payoff diagram would look like this Once again, this payoff diagram just incorporates the price of the option.발음듣기
대기중
This is just the value at expiration, depending upon what the value of the stock is at expiration.발음듣기
대기중
Now this is just a situation if you were to buy an option but there has to be someone on the other side of the contract someone who's holding, agreeing to buy the option for you.발음듣기
대기중
So you could actually have the writer, you could actually have the writer, of the put the payoff diagram we just showed is the person who owns the put, but someone else had to have created the put.발음듣기
대기중
'"I will give you the right to sell, to sell me the stock at $50, up to some expiration date."발음듣기
대기중
Well if this guy is going to be able to make $50, this guy over here the writer of the put, the writer of the put is going to lose $50.발음듣기
대기중
He's going to have to essentially go out he's actually going to have to buy that $50 put or buy that $50 stock from this person because he has to uphold his side of the transaction but he's buying something for $50 that's worthless because based over,발음듣기
대기중
at this end of the axis, the stock would be worth nothing so he's taking a $50 loss, all the way to him not having to do anything because the put holder won't actually exercise their options if their stock price is $50, so their payoff diagram is going to look like this.발음듣기
대기중
So you can see it's actually the mirror image of the payoff diagram of this person on the other side of the contract.발음듣기
대기중
And if you were to add these two payoff diagrams, you would be neutral, because all of the money is exchanging hands between the buyer and the seller of the put.발음듣기
대기중
If you look at the actual profit or loss if the put is not exercised then the writer of the put essentially just got a free $10.발음듣기
대기중
He created the put and sold it to that guy for $10 the put is not exercised, he gets to keep that $10.발음듣기
대기중
But then if the stock goes down and he's forced to buy the stock from the owner of the put he has to buy it because that's his side of the deal then all of a sudden he loses money.발음듣기
대기중
He would take a $50 loss, but he paid the $10 on the actual price of the option so it would be a negative $40 profit.발음듣기
