One of the characteristics involving option trades that is certainly particularly vexing to the new trader is the nearly infinite variation by which individual options might be combined to produce a seemingly infinite array of options. These combinations of various individual options are more than a theoretical exercise; each individual combination often produces an exclusive Profit & Loss blackberry curve.
We have discussed earlier the concept of a calendar spread. To review in brief, a calendar spread is constructed simply by selling a quicker dated option and purchasing a longer dated choice at the same affect price in the same type of option, possibly puts or phone calls. The profit engine will be the difference in the corrosion rate of the time quality between the two alternatives. A fundamental characteristic of options is that the time high quality embedded within a shorter dated option decays at a quicker rate than that covered within a longer old option.
Additional characteristics of this trade construction are that the array of profitability extends over the variably broad range and the maximum potential profitability takes place at options conclusion when the price of the root is precisely at the hit price of the calendar.
Before the trader goes in trades such as this, it is important to understand the pertinent risk factors. I find it beneficial when thinking when it comes to risk to remember that alternative trades must be regarded as in terms of the risk introduced by each of the three primal forces of alternatives: time, price of the root, and implied unpredictability.
In the case of a calendar trade, the passage of time along with the inevitable erosion of your energy premium is the fundamental revenue engine. Generally, chance in the calendar trade decreases with the passing of time as more of the eroding time premium accrues to the benefit of the trade.
The effect the next primal force, the price of the main, can be easily seen in the actual graph above; pay particular attention to the fact that there is both a great upside and disadvantage breakeven point and the trade must be managed with both these profitability borders in mind.
Finally, the usually overlooked impact of the implied volatility should be considered. This element is the most frequently overlooked variable in the trade but is arguably the key factor in deciding to use this trade structure. The starting point for considering this variable is the current status with the implied volatility regarded within a historical composition. It is important that the longer out dated options not be inside the upper portion of their particular historical volatility assortment. If one were to purchase these options at the initiation of the calendar spread, there would be an important risk of volatility fall as the implied movements was to revert to the mean. This would negatively impact the trade.
