American call options발음듣기

Let's say you think very highly of company ABCD, and you're convinced that the stock price will go up from its current trading price of $50 per share.발음듣기

You could do two things: you could either just buy the stock for $50 and hope that the price goes up, or — and I made this price up — you could go to an options exchange and, for the price of $5, you could buy the option to buy this stock over the next month.발음듣기

It expires in one month. Usually it'll be a specific date, but I'm just saying, one month from the date you buy the option, and it gives you the option to buy the stock for $60 a share.발음듣기

And the type of option I've just described is called an American option.발음듣기

And it can be compared to a European option.발음듣기

An American option allows you to exercise the option — to actually buy the stock — any time from the time you have the option until the expiration.발음듣기

On a European option, you only have the option, you can only exercise it on the expiration.발음듣기

But we'll just focus on the American.발음듣기

Now let's think about the different outcomes depending on what the stock does.발음듣기

So let's say the stock actually does do what you think it does.발음듣기

Let's say it goes up and then it goes down.발음듣기

Let's say that you're really good at calling stock price tops.발음듣기

And then right over here, let's take the two scenarios.발음듣기

Let's take the scenario where you bought the stock and then you sell the stock.발음듣기

So you bought at $50, and then over here right at the top, you're just a perfect market caller, you're able to sell the stock at $80.발음듣기

So let's just think about the different profit scenarios.발음듣기

So here we have an end price of $80 per share.발음듣기

If you had bought the stock for $50 and now sold it at $80, you will have a profit of $30.발음듣기

Now let's think about if, instead of buying the stock, you bought the option today.발음듣기

So if you bought the option, same thing, when the stock goes up to here, you'll say, "Oh, I think that's the top for the stock, let me exercise my option.발음듣기

So I'm going to exercise my option which gives me the right to buy the stock at $60 a share."발음듣기

So you're going to buy it at $60 a share, right over here, and you can immediately sell it for $80 a share.발음듣기

So you could make $20 on that transaction, but, of course, you paid $5 for the option itself.발음듣기

So you make $20 on the difference between $80 and $60, but you had to pay $5.발음듣기

So you have a $15 profit.발음듣기

So there it says, hey, look, maybe I was better off buying the stock!발음듣기

And even there I'd say, look, to buy the stock you had to put $50 of capital at risk.발음듣기

To buy the option, you only had to put $5 of capital at risk.발음듣기

And to see that, imagine the negative scenario, where instead of the stock doing that, let's say the stock just completely plummets after you buy.발음듣기

And it goes all the way down to $20.발음듣기

Now in the situation with the stock, let's say right over there you've just had enough.발음듣기

You say, "I just want to sell the stock."발음듣기

So this is an end price of $20.발음듣기

In that situation, you bought for $50, sell for $20, you will lose $30.발음듣기

But in the option scenario, this entire time that it was plummeting, you'll say, "I just won't exercise the option."발음듣기

The option is "out of the money."발음듣기

It makes no sense for me to exercise it.발음듣기

So you just won't exercise the option.발음듣기

So you'll only lose the price that you paid for the option.발음듣기

You'll only lose your $5.발음듣기
