Before embarking on your adventurous journey into the wondrous world of Options trading, it would probably be a good idea to familiarize yourself with what these trading
instruments actually are. The following resources will help you do just that. You will want to pay particularly close attention to "Long Option Spread" Strategies
since that is what the Expiry Week website is all about.
Options Basics Tutorial
You can navigate to the Option Evaluator from the Expiry Week Home page by clicking on the link labeled "Option Evaluator".
The Entry Date on the Evaluator shows the trading day for which the calculations are valid. You can use this date to determine when Expiry Week has finished performing its nightly updates.
We provide analysis for the following option strategies.
The date on which an option ceases to exist.Stock Target
If the selected strategy is "Buy Call Spread", an upper target price for the stock will be displayed. If the selected strategy is "Buy Put Spread", a lower target price for the stock will be displayed. The upper and lower stock targets are derived from the average amount the stock can be expected to move based on the number of trading days remaining between the displayed Entry Date and Expiry Date. We determine the average amount a stock can be expected to move using the implied volatility of the underlying options.Target Return
We calculate returns based on the assumption the stock will close exactly at our projected target on expiry day. Since there are bid and ask related costs associated with closing each leg of an option position, you should expect to receive a bit less than the actual intrinsic value of your position if you sell it on the open market on expiry day. To adjust for this reality Expiry Week uses 95% of an Option Spread's maximum expected value when calculating Target Return.Model Rating
A stock's Model Rating is a prediction that a stock will move up or down in price between the Entry Date and the currently selected Expiry Date. We use a mathematical definition of directional movement based on the following rules.
The Buy Strike is the option strike price at which you should position the long side of your trade; this will always be the strike price that is closest to
the current stock price. The Sell Strike is the option strike price at which you should position the short side of your trade; this will always be the strike
price that is closest to our projected Stock Target (Lower Target for a Put Spread and Upper target for a Call Spread).
Visit our Trade Options With A Mathematical Edge page to find out why these are the optimal strike prices to choose.
You can change the Buy Strike and Sell Strike on the evaluator when evaluating the potential return on a particular option position.
If you wish to be more aggressive you can push the buy strike closer to the projected target. This will increase you potential return but also increase the amount the stock needs to move in order for you to break even. A good rule of thumb is to only take a position if the target return is at least 100% so that the potential risk on each and every trade is offset by an equal or greater potential reward.
This represents the net cost associated with the Option Strategy you are executing. You need to supply the price of the option position manually and then press the Evaluate button to get the value of Target Return.
The Option Evaluator displays a link in the upper right corner labeled "Option Screener". Clicking this link will display a list of the 25 best available trades for the currently selected Product, Model, Strategy and Expiry Date. Trade candidates are displayed sorted by maximum return potential so that you can explore each candidate working down from the top of the list until you find one that you feel comfortable trading. Clicking on a symbol in the Option Screener will drop that symbol into the Evaluator along with the previous days closing Stock Price. Supply the current stock price and press "Submit" to get an updated target price for the stock along with the optimal Buy and Sell Strikes to use when buying a Spread.Product:
