Last time we spoke I introduced you to volatility. Now after a break for the holidays, I'm going to teach you how to take advantage of it! Today, we're going to talk about a new option strategy that takes advantage of both rising volatility and time decay, called the calendar spread.
Just a Matter of Time…
So what is the calendar spread? And why is it a useful option strategy to know about? The calendar spread is an interesting strategy. In many ways it's a mix of writing a covered call and buying a call with a different expiration date at the same time. Let me break it down for you.
A calendar spread can be constructed with both calls and puts depending on your general opinion of the market or stock. However, for the sake of clarity we will only consider a spread involving calls. Because we are considering calls, we have an overall bullish opinion of the stock we are constructing the spread with. However, with a calendar spread we are neutral in the short-term. So what exactly does a calendar spread entail?
To create a calendar spread you buy a long-term option and sell a short-term option of the same strike price. The idea is that you will take advantage of the heightened time decay of the short-term option and make substantial profits when it expires (hopefully worthless.) After that time you can either close the position, or keep your long-term option (which you've now obtained at a nice discount), and let your view of the market take its course.
Another nifty feature of the calendar spread is how an increase in implied volatility affects the position. As implied volatility increases, the price of both calls and puts also increase. This increase in price has a larger effect on long-term options than short-term options, thus when this happens a calendar spreader benefits, and sometimes quite substantially.
Personally, I find the calendar spread an incredibly attractive strategy. Not only does it limit your risk exposure (your maximum loss is the amount paid to open the position), but it also allows for a very hefty profit. At times the shorter term option will expire and leave your longer term option with 100%+ in gains! What surer profit is to be had in the option's market than that gained from time decay?

Now that we've covered some of the more basic option strategies, it is time to introduce volatility. Volatility is a key factor when trading stock options. What exactly is volatility? And how does it affect stock options?
Defining Volatility
There are some very technical definitions of volatility, and if you're interested in reading them you can at: http://www.investopedia.com/terms/v/volatility.asp. However, I would like to define volatility in a less technical way. If a stock tends to decline or appreciate in rapid bursts it is considered to be volatile. That is, we can expect the stock to move a decent amount (either up or down) percentage-wise during our time holding it. On the other hand, Blue chips and other slow moving stocks aren't very volatile. They move with the market, and they don't move very fast in either direction. Because some stocks are more likely to change prices rapidly their options are more expensive than those of a slow moving stock. However, there is a catch to this. At times you may notice a stock that hasn't moved much at all recently, and yet their options are incredibly pricey! This stock might look like a good candidate to sell calls against, but doing so may be unwise.
Two Types of Volatility
Although, the previously mentioned stock may have seemed to be an incredible opportunity to write covered calls, there was likely another reason for the overpriced options that would put your position at risk. The market considers two types of volatility: historical and implied. Historical volatility is a measure of how volatile the stock has been in the past. This statistic can be very telling, especially when determining how much to pay for an option. However, implied volatility is what is actually used when pricing options. What is 'implied' volatility? Implied volatility is how much the market expects the stock to move over the life of the option. If a biopharmaceutical company is waiting for some huge drug decision by the FDA their options will be incredibly pricey; when the decision is finally made the price of the options will collapse, but their stock price may too. In a sense it is excitement that drives options to become overpriced. When the excitement is gone, your money is too! Be wary of overpriced options!
Next time we'll talk about calendar spreads and learn more about volatility. After that I'll introduce you to a few option pricing calculator and more complex strategies involving options.

Yesterday, we talked about credit and debit spreads. We learned the pros and cons of each, and today we are ready to tackle a new aspect of spreading risk with bull and bear spreads. Although, many different setups can be created, there are basically two different risk appetites that can be achieved with bull and bear spreads.
Phil and Bob Follow Buffet
Our good friends Phil and Bob have yet again discovered a trade they like. Recently, Warren Buffet's company Berkshire Hathaway has acquired a large stake in the oil giant Exxon Mobil (Stock Symbol XOM.) Warren thinks inflation will soon set in and commodity prices will soar. Bob and Phil think Warren might be right, so they have decided to take up an option position in XOM. To best take advantage of this opportunity, Bob and Phil are both going to set up bull spreads. However, Bob and Phil aren't really sure how high XOM will go. Bob, the more conservative of the two, sees 80.00 by January, a large, but realistic move for XOM. On the other hand, Phil finds such a target likely, but believes the momentum will build and it will take XOM beyond its fundamental limits, all the way to 85.00.
Bob will set up a 75.00/80.00 spread. He will buy XOM January 75.00 calls, and sell January 80.00 calls for a net debit of 1.85. If XOM is at our beyond 80.00 when the option expires in January his profit will be 3.15, a significant amount for what seems to be a reasonable trade. Phil will take a different route. Phil will buy the January 80.00 calls, and sell January 85.00 calls for a net debit of .55. If XOM is at or above 85.00 when the options expire in January, Phil will have a large profit of 4.45! A very significant profit for such a small debit, but such a profit would require a very large move. A move that is unlikely for XOM.
As you can see, bull and bear spreads come in two different flavors. When the option you buy is more than one strike price away from the current price it is considered a more speculative and aggressive position (a Phil position, if you will.) In contrast, when the option is nearest the current strike price, it is considered a standard level of risk for a bull or bear spread, and a less risky position than simply buying a call or put.
You now know a good deal about bull and bear spreads. You can set them up in a variety of ways, debit or credit, aggressive or not-so-aggressive, bull or bear. As always, practice in a virtual account before you trade such spreads in a live account, it will save you money in the long run. Next, I will introduce you to one of the most complex and important topics in the world of options: volatility. Along with this, we will talk about the calendar spread. The calendar spread is a particularly useful strategy that offers a variety of unique opportunities.
Until next time,

Today we are going to explain the difference between a credit and debit spread. Overall, it is a simple concept, but must be explained before we continue talking about spreading risk.
Learning to Speak Optionese: Debit and Credit Spreads
With every spreading strategy there are two different setups, the credit spread or the debit spread.
A credit spread is created when you sell a call or put and buy a call or put of lesser value. Thus when you set up the spread you take in a net credit. If you're a bull you'll sell a put and buy a cheaper put. If you're a bear you'll sell a call and buy a cheaper call.
A debit spread is created when you buy a call and sell a call of lesser value. To open the position you must pay out a premium, or 'debit.' This is the classic spread I talked about when describing bull and bear spreads. Generally, people tend to open debit spreads. However, both types of spreads offer different advantages.
Which Spread Suits You?
Although debit spreads are used most often, you might prefer to use a credit spread. Let's start by talking about the advantages of using a credit spread.
Credit spreads make money when the trade moves in the direction you anticipated, which is to be expected. On top of that, if the underlying stock sits and does nothing all the way into expiration you make money off of the time decay! This is the sort-of double whammy that makes credit spreading very attractive. In two out of three market environments, credit spreads make money; it's good to have the odds on your side! Also, credit spreads don't cost anything to set up. Because you are taking in a credit, you don't have to pay any money to open the position! A lot of people like the idea of this, but I believe this is often deceiving. What you must have to set up a credit spread is margin (money in your account to back up the potential loss.) You must meet the margin for the maximum loss your position can suffer. What is the maximum loss? At expiration, your max loss is the distance between the two strike prices minus whatever time premium you received, (in the case of a call spread, higher strike price – lower strike price – time premium). This can be a substantial amount of money! If the spread between the strikes is a dollar you're talking about 100 bucks per spread, but more likely it will be 5, a whopping 500 dollars per spread! For this reason, I tend to stay away from credit spreads. I am not saying that credit spreads aren't great, they are - I even trade a particular strategy revolving around them – however, under most circumstances they are a bit too risky for my taste.
Generally, I create debit spreads. Debit spreads suffer from time decay, and if the position does not move in your favor, you can lose all the money you originally put out to open the position. Another problem I often have with debit spreads is liquidity issues with the call or put I am selling (the one of lesser value), I often ended up overpaying to open the position (buying at the ask for one call/put, selling at the bid for the lesser call/put), and then overpaying to close the position! Despite this, when the options have enough liquidity a debit spread is a great strategy to minimize capital exposure.
Overall, both credit and debit spreads offer unique opportunities; although, I prefer debit spreads you may prefer the prospects of credit spreads. Both spreads have their perks and pitfalls, and they can be rather quirky. I recommend experimenting with both types of spreads in a virtual account before you actually begin trading them. Tomorrow we're going to talk a bit more about spreading, and later this week we'll move on to talking about trade adjustments and how you can hedge and protect positions using options.

Today, we're going to talk about bull and bear spreads. This week we've already learned about buying puts and calls. Now we're going to build off of our previous knowledge and talk about spreads. Generally, the bull spread is a strategy that uses calls. A bear spread, on the other hand, uses puts. We will start by talking about bull spreads.
What is a bull spread? A standard bull spread requires the purchase of a call and the sale of a call with a higher strike price. Doing this limits profit potential, but because you take in the premium for selling the call with the higher strike price, your downside is limited.
So when should you buy a bull spread over a simple long call? Generally, bull spreads underperform long calls in a rising market. However, as expiration gets near, or when the position does not move in your favor, a bull spread is superior. Personally, I like bull spreads because they risk less capital than a simple long call. However, because I momentum trade, I generally just purchase long calls.
Another reason bull and bear spreads are attractive is that they take advantage of time decay. Because you are short a call at the same time that you are long a call your overall time decay is significantly less than were you just long a call. This is especially nice during option expiration week!
Now, let's introduce the bear spread.
What is a bear spread? A standard bear spread requires the purchase of a put and the sale of a put with a lower strike price. Doing this limits profit potential, but because you take in the premium for selling the call with the higher strike price, your downside is limited.
Conceptually, bull and bear spreads share the same perks, and suffer from the same pitfalls. We'll talk more in depth about the advantages and disadvantages of different spreads in the next post. After that, we'll discuss credit and debit spreads, and other spreading strategies.
Until then,

Hey guys, this week we'll finally be covering some basic option positions! I put the post about buying puts to bet on a decline up a little early but I'd just like to overview what we'll be talking about this week.
Something else to note, I've decided to wait to talk about how options are priced until we cover the Greeks. That information will fit better there, and hopefully, help you understand it better.
See you soon,
