In What is an Option? - Part 1, I covered the two types of options - a put and a call.
Here are some option attributes:
- options are like ice cubes, they are worth something and then melt away to nothing ($0.00) over time.
- one option typically represents 100 shares of stock.
- there is an expiration date that is set - think of this as the day the option is all done melting away to $0.00.
- there is also a strike price or set price - this is the price of the stock that is set no matter what the stock is worth on the expiration date.
- expiration day is always the third Friday of every month. That is when your option is worth $0.00. Typically at the end of the trading day on the third Friday of the month that your option expires.
- a call option allows you to buy the 100 shares of stock at a fixed priced on or before a fixed day, expiration day.
But here’s the kicker - we don’t want to buy the stock. As options traders we want the stock to go up so our call option goes up as well. If there is enough time left before our call option expires and the stock value goes up, most likely the value of our our call option will go up.
In reality, a call option allows us to buy the 100 shares of stock for a fixed price no matter what the market price is for the stock. If we bought a $10.00 call option on an $8.00 a share stock and it went up to $12.00 a share, we certainly could buy the 100 shares of stock for $10.00 a share rather than $12.00 a share because we paid for the right to do that when we bought our call option. WOW!!
I know that’s a lot to take in but read it over and over until you get it. If you have any questions post them in the comments area.
However, if that stock went up to $12.00 a share, that means our call option would go up as well. As long as we haven’t reached the expiration date, our call option should be worth more than what we paid for it. Remember, it costs us a lot less to buy a call option than 100 shares of stock.
The Down Side
Yes, there’s a down side. If the value of the stock stays the same or goes down and stays that way up to the end of expiration day, then we’ll lose money. For example, if we buy a call option on a stock that is worth $8.00 a share and we hope it goes to $10.00 a share or more but it never does, then our option will go down and down with every passing day until expiration. Remember that melting ice cube?
Another Example
Like the POZN call option we talked about last week and profited handsomely (on paper anyway) on, we’ll take a look at another one this week. The stock is Taiwan Semiconductor, symbol TSM. The October 10 calls are being bought up like something crazy!!
Look at the options table below taken from Big Charts:

That is what we call institutional buyers coming in and hoping to snag a deal because they know something we don’t or they’re just desperate to make some money at the end of the summer.
We call these guys the “smart money”. Well, let’s hope that’s all true.
Again for this example, we could buy 1 call option contract for $50.00 (.50 times 100 shares of stock) or we could really gamble and buy 10 contracts for $500.00 (.50 times 1,000) or if we’re feeling really giddy we could buy 100 contracts for $5,000.00 (.50 times 10,000 shares of stock) . That sounds good to me.
We’ll paper trade this, which again means we’ll write it down on paper (or this blog) that we paid $5,000.00 for 100 contracts of the September 10 Calls, option symbol TSMJB.
On another note, if you want to do this trade over at the CBOE, you can use their Virtual Trade Tool to see what happens. Maybe I’ll do a post on their Virtual Trade Tool sometime. But if you feel you understand some of this go over and read about the Virtual Trade Tool and give it a try. If not, stop back soon to see what happens with this trade.
If we get a nice move up between now and the third Friday in October 2007 we’ll make a good chunk of change and be done with it.
We’ll also be looking to exit this position if we lose too much as well. We won’t set a limit of what we want to make just yet since we have over a month to watch this trade. We also won’t set a limit on the downside just yet because of the time that we have and the fact that stocks and their options can jump all over the place in a short period of time.
If you have any question about options let me know and always remember, “Pigs get fat, hogs get slaughtered!!”
