Glossary of Terms- Stocks and Options

Stock market terminology can be daunting, and stock options can be even
harder to understand. We have put together a glossary of common terms relating to options trading that may help.

Rather than list them in traditional alphabetical order, we have listed each in order of importance for a basic understanding of stock options trading.

Some very basic terms you may have heard before:

Bearish view is where the stock market or stock is expected to decline and usually is referenced by it's technical indicators and/or support/resistance.

Bullish a view someone has where they are expecting the stock market, or a stock price to rise.

Neutral is a view someone has where they are neither bearish or bullish. There are options trading strategies suited to this, requiring little or no movement.

Chart Indicators are the technical elements associated with a Stock Chart and a glossary of the various indicators (MACD, Stochastics, RSI, Williams, DMI, etc) are located in the Foundtion Learning Course.

Stock Options give the holder the right to buy or sell particular shares at a fixed pre-determined price within a fixed period of time. Stock options can be traded in the same way that the underlying stock can be bought and sold.

Underlying Security is the stock that an option taker has the right to buy or sell if they choose to exercise.

Some terms that relate to the mechanics of stock options:

Call Options give the holder the right to buy the underlying stock at a fixed pre-determined price within a certain, fixed period of time.

Put Options give the holder the right to sell the underlying stock at a fixed pre-determined price within a certain, fixed period of time.

Strike price This is the fixed, pre-determined price at which you can buy or sell the shares. This cannot be changed throughout the life of the option contract.

Expiry This is the date at which the option contract expires. This cannot be changed throughout the life of the option, and there after the contract is worthless.

Exercise The process of fulfilling the put option contract and buying or selling the shares. This can be done any time up to and including the option expiry date.

Premium The amount you pay for the option contract. Each stock has set strike prices for trading. Depending on where the strike price is in relation to the current share price,influences the amount you pay. Premium is the sum of both the options intrinsic valueand time value.

Contract Size The amount of underlying stock covered by an option contract. In the U.S this is 100 shares, and Australia it is 1,000 shares. This can vary at times. A broker is able to confirm this for you.

Writer is a trader or investor who sells an option.
Taker is a trader or investor who buys an option contract.

Some terms that relate to the pricing and values of stock options:

At the Money when an options strike price is the same as the current stock price, it is said to be at the money.

In the Money A call option is in-the-money when the underlying stock price is higher than the strike price of the call, and a put option is in-the-money when the stock price isbelow the strike price. The option would have intrinsic value.

Out of the Money A call option is out-of-the-money when the stock price is below the strike price, and a put option is out-of-the-money when the stock price is higher than the strike price. The option would have no intrinsic value.

Intrinsic Value is the difference between the current stock price and the strike price.This is the amount by which an option is in the money, and indicates the value of an option if it were to expire right now.

Time Value is the difference between an options current value and the intrinsic value.

Time Decay Options are made up of time value and intrinsic value. As you get closer tothe expiry date, the option value diminishes. This is called time decay. When you buy an option, you are buying time.

Fair Value is used to describe the value of an option as calculated by a mathematical model. Also used to indicate intrinsic value.

Theoretical Value The price of an option as calculated by a mathematical model.Overvalued describes a stock trading at a higher price than it logically should.
