Volatility Events, Predictions and a Piece of Cake

Option trading is easy. Well, let me qualify that statement just a bit. To be fair, options are more complicated than more simple, linear assets like stocks. But there are some elements to options’ pricing that actually make them a little easier to trade from a valuation standpoint. To find out more about this feel free to visit the options information section of our website.

The most important thing to consider is predictability. You probably receive many unsolicited emails telling you how so-and-so can predict the market with 100% certainty and make you a billionaire overnight. On the other side of that coin, there is not a professor alive who will tell you that it is possible to predict the direction of the stock market with any statistical significance. The truth probably lies somewhere in the middle. But one thing for sure: predicting the direction of a stock is though, and you’ll be wrong often.

But, aside from directional implications of the underlying stock, there is an important pricing factor to options that is much more predictable: volatility shifts resulting from expected volatility events. All options have an imbedded component to their pricing relating to expected-future volatility. This is called implied volatility. It can be thought of as the expected future volatility implied by the market.

Sometimes volatility is quite predictable, and therefore, fluctuations in option prices resulting from implied volatility changes can be likewise predictable. So-called volatility events include earnings, Fed announcements, CPI, PPI, Retail Sales, Payrolls, GDP and more. Volatility events are often scheduled far in advance. Just google a financial calendar and see when CPI is scheduled to be released six months from now—you’ll easily find that information. Unemployment figures are always the first Friday of the month. And so on.

When volatility events are imminent, options get more expensive. Why? Hedgers and speculators brace for a potential move by buying options, creating price-pressuring demand. Look at a chart of implied volatility for a typical stock option class and take a look at its value in the few days leading up to earnings. Typically, it will increase right before earnings. Then afterwards, it tends to fall right back to its normal range.

Scheduled volatility events help option traders analyze the ebb and flow of option premium levels with the precision of predicting the moon cycle. But all volatility events are not predictable—only those that are regularly scheduled. Sometimes, volatility events come out of nowhere. Takeovers, CFOs cooking the books, these sort of things can take a trader by surprise.

Though not all volatility events are predictable, the fact that some are provides great value to option traders. Imagine knowing that a stock would almost always rise at a certain date every quarter! This makes option trading a little easier than stock trading in my opinion. Maybe not quite a piece of cake; but still advantageous over trading stocks.

It Happens Every Quarter

Classic parables of warning are often offered to traders considering exploring the world of option trading by those who do not understand the physiology of the various option “beasts”.  These “instructive” stories have various iterations, but one frequently repeated story has a core point of “wisdom” that can be illustrated by the following frequently encountered sequence of events:  A trader buys call options shortly ahead of correctly predicting better than expected earnings and the expected price rise of the underlying.  When the options open following this increase in price of the underlying, he has gained little if any profit from his long call.  The “obvious” conclusion?  The market makers are thieves, the options game is rigged, and I need to look elsewhere for trading opportunities.

Perhaps we should not throw the baby out with the bath water quite yet.  Is there some rational explanation for this behavior?  In a word, yes, there is.  In order to understand the phenomenon, we need to consider the physiology of an option.

One of the major determinants of the magnitude of the option time premium (aka extrinsic premium) is the implied volatility (IV).  There are various available databases available to track the history of this value, and a reproducibly observed phenomenon is that IV almost always stereotypically correlated with earnings releases. It typically spikes in anticipation of the release and the uncertainty surrounding this information and collapses very quickly following the release and the resultant price reaction of the underlying to this information.

It is this rapid, predictable decline in IV that results in the commonly observed sequence of events related in our parable.  If the purchased option contained significant time premium, it will have been devastated by the collapse of IV and the trader’s anticipated profits will have been erased or significantly reduced.

Armed with this knowledge, is there any way to immunize the trade against this sequence of events?  As you may have guessed, the answer is yes.  While description of the various strategies is beyond the scope of this brief post, suffice it to say that the category of vega negative or vega neutral trades holds the key to dealing successfully with this situation.
