Stock Options - The Basics
By Russ O Brown
My last article touched on the volatility and some basics of volatility's influence on options. Now I would like to start with the basics and give our readers an overview of how options function. This and the following articles in this options series will not be a complete options education. However it should provide a foundation on which you can build a solid understanding on how to properly use options. Some of the references used, assume that you have an understanding of trading stocks.
In order to fully understand options we must start with the basics, this is our foundation. Understanding terms and definitions is vital to understanding how to properly implement options. Some important terms and definitions follow:
Call~ May be a bullish position. The right to, but not an obligation to purchase a given amount of stock (usually in quantities of 100 shares) for a pre-determined price, at a pre-determined future date.
Put~ May be a bearish position. The right to, but not the obligation to sell a given amount of stock (usually in quantities of 100 shares) for a pre-determined price, at a pre-determined future date.
Trend ~ The direction of stocks or indices over a minimum of five trading periods.
Greeks~ The underlying factors that drive the price of options.
Delta ~ the amount an option's theoretical value will change for a corresponding one-unit (point or dollar) change in the price of the underlying stock (equity option), or value of the underlying index (index option).
Gamma ~ the amount an option's delta will change for a corresponding one-unit (point or dollar) change in the price of the underlying stock (equity option), or value of the underlying index (index option). Also known as the Delta of the Delta.
Rho ~ the amount an option's theoretical value will change for a corresponding one-unit (percentage-point) change in the interest rate used to price the option contract.
Theta ~ the amount an option's theoretical value will change for a corresponding one-unit (one day) change in the number of days to an options expiration. It is a measurement of an option's theoretical time decay.
Vega ~ the amount an option's theoretical value will change for a corresponding one-unit (one percentage-point) change in the contract's implied volatility.
IV ~ a consensus in the marketplace of an underlying stock or index's expected volatility as predicted, or implied, by an option's price. It can be calculated with an option pricing model as the volatility assumption that would be used to generate a theoretical value for a call or put that is equal to its current market price, and is expressed as annualized standard deviation in percentage form.
Bullish~ Believing the price of stocks will trend higher.
Bearish ~ Believing the price of stocks will trend lower.
Neutral ~ When the market trades in a range over an extended time.
Expiration ~ (American style options) Option contracts technically expire the third Saturday of each month, since the stock markets are closed on Saturday it is generally accepted as the third Friday of each month.
Bid ~ The price the brokerage firm will pay per share for an options contract.
Ask ~ The price a brokerage firm will accept per share for an options contract.
Spread ~ The difference of the bid and ask price.
Exercise ~ The decision to purchase the underlying equity at the option contract strike price.
Assignment ~ For an equity option, the writer must sell (for a call) or buy (for a put) 100 shares of underlying stock at the strike price per contract.
Long ~ Holding a position in anticipation of the equity continuing in the present trend.
Short ~ The investor has assumed the obligation to buy 100 underlying shares at the strike price if assigned on the short put.
Time Decay ~ The premium of at- and out-of-the-money options consists only of time value. It is time value that is affected by time decay as well as changing volatility, interest rates and dividends. Also termed extrinsic value.
Leaps ~ Long-term Equity AnticiPation Securities, or LEAPS, are long-term option contracts. Equity LEAPS calls and puts can have expirations up to three years into the future, and expire in January of their expiration years. Index LEAPS may have expirations of up to five years into the future and generally expire in December of their expiration years.
These are the basic options definitions; there are more complex definitions for the varied strategies; which will be covered in later articles. I know terms and definitions are not the adrenaline pumping rush of actually placing a trade. However, I have found over the years that having a good understanding of the basics makes it easier to learn the more complex attributes. Understanding these terms, what they mean, when, and where they are used, is vital before entering a position. Another important aspect prior to entering a position is to have an understanding of the terms used by your broker and how to place the correct limits on your order.
Prior to entering an option position make sure you fully understand all the mechanics of your chosen strategy. Before implementing a strategy that is new to you; trade it on paper until you are comfortable with how it works and how to exit the position correctly. As prior articles have stated, have a plan and trade your plan. When in doubt stay out of the trade, there will always be another opportunity.
