The concept of volatility, and especially implied volatility is extremely important for option traders. We often refer to implied volatility, for it is the foundation of many of our strategies. However, when meeting the public, I find that many people don't have a clear concept of what implied volatility is, so this article will be educational for some readers, and merely review for others.

We have, in the past, often written about the fact that options can be used to help spot "hot" stocks, such as potential takeover candidates. Option premiums tend to inflate and/or option volume tends to increase prior to a major fundamental news event concerning the stock. The reason for this, of course, is that "insiders" — those who have prior knowledge of the news, or at least have a very educated guess — buy options because of the tremendous leverage available from the profitable purchase of an option.

Over the years, we have written many times about the problems in predicting or estimating volatility. However, it is necessary to attempt the task, because it is so crucial in determining which (option) strategies can be used.

What Is A “90% Day?”
A “90% Day” must satisfy two criteria: 1) either advances or declines comprise more than 90% of all issues that moved that day (unchanged issues don’t count), and 2) either advancing or declining volume was 90% or more of the sum of advancing and declining volume.

The question posed in the title above is one that should probably be asked more often than it is. Somehow, it has become something of a consensus in the option trading community that implied and historical (actual) volatility will converge. That’s not really true – at least not in the short term. Moreover, even if they do converge, which one was right to begin with – implied or historical? That is, did implied volatility move to get more in line with actual movements of the underlying, or did the stock’s movement speed up or slow down to get in line with implied volatility? In this article, we’ll look at some examples of what really happens with respect to implied and historical volatility, and we’ll try to draw some conclusions regarding this comparison.

Volatility
Volatility is merely the term that we use to describe how fast a stock, future, or index changes in price. When we speak of volatility in connection with options, there are two types of volatility that are important: historical volatility, which is a number that can be calculated mathematically by seeing how fast the stock has been changing in price over the past 10 days, 20 days, or any other time period that we want to examine. The other type of volatility that is important for option traders is implied volatility. Implied volatility is what the options are "saying" about future volatility: if it is high, then the options are predicting that the underlying instrument is going to become more volatile in the (near) future; if it is low, then the options are predicting that the volatility of the underlying will decrease. Thus there may be a difference between the historical and implied volatility. If the difference is large enough, then one can use options strategies to create a position with an "edge" — the "edge" being the differential between these two types of volatility.

We often write about volatility since it is the variable which most directly determines the price of an option. Oh, sure, the other variables are important — stock price, strike price, and time to expiration — but those are determinant things since we always know their value at any given time. However, volatility is the big question mark, the one variable that dances to its own beat, that can make or break a strategy even if the stock or futures price behaves as one expected.

In our last issue, the feature article discussed whether it might sometimes be preferable to trade the underlying stock as opposed to buying an at- or slightly in-the-money option. This week’s article is a follow-up to that discussion: we are going to look at various option strategies that are, in effect, almost like owning the underlying stock. The potential advantage of these option strategies is that they behave much like stock so time decay is not a major drag on the position. Moreover, leverage is available through these strategies (not as much leverage as one would have in an option, but decent leverage nonetheless). Leverage is neither good nor bad, but for those who want it, this is a way to achieve it without subjecting a position to onerous time decay.

We regularly have a column entitled "Volatility Trading". In this article, we want to look at the strategies that are applicable when one finds implied volatility is substantially out of line with where it "usually" is. As you will see, there is often more than one way to approach the situation, depending on which strategy you choose. You might choose to limit risk, but not at the expense of lowering your prospective profits unnecessarily; on the other hand, you want·to be prudent about your risk-taking.

The common perception among option traders is that option buying is the “best” approach to a speculative situation because of the great leverage that the calls or puts provide. But in many cases, ranging from extremely short-term holding periods to ones of more moderate length, where limited stock moves are likely, one may be better served by trading the underlying entity than by buying options. In this article, we’ll try to answer the question of which is better, an option position or a stock position. It turns out that the answer may be dependent on what one’s objectives are. Also, we’ll reconstruct some trading from past recommendations to see the option vs. stock results.
