What Are Options?

Options are financial derivatives that give the buyer the right, but not the obligation, to buy or sell an underlying asset at a specified price within a set time period. Call and put options are the two main categories of options.

Types of Options: Call and Put

  • Call Options: These provide the holder the right to buy the underlying asset.
  • Put options: Grant the holder the authority to liquidate the underlying asset. The Basics of Options Trading

Options trading involves speculating on the future direction of stock prices, but unlike stocks, options have expiration dates and can be complex due to various influencing factors. The following are some essential terms to understand:

  • Underlying Asset: The security on which the option is based (e.g., stocks, indices).
  • Option Premium: The price paid for the option.
  • Strike Price: The set amount that can be used to exercise the option.

The date by which an option expires and loses all of its value is known as its expiration date.

How Call Options Work

A call option gives you the right to buy the underlying asset at the strike price before the expiration date. Imagine you believe that a company's stock, currently priced at $50, will rise. You could buy a call option with a strike price of $55 expiring in three months. If the stock price exceeds $55 within that period, you can exercise your option to buy the stock at $55, potentially profiting from the price difference.


How Put Options Work

A put option, on the other hand, gives you the right to sell the underlying asset at the strike price before the expiration date. Suppose you own a stock currently priced at $50 and you fear it will drop. You can purchase a put option with a strike price of $45. If the stock falls below $45, you can sell it at the higher strike price, mitigating your losses.


Understanding Option Premiums

The option premium is the price you pay to purchase an option. 

It comprises two main components:


Time Value: the variation between the strike price and the underlying asset's current price.

Factors affecting option premiums include the underlying asset's price, volatility, time until expiration, and interest rates.


The Role of Strike Price

The strike price is crucial as it determines the level at which the option can be exercised. A call option is profitable if the stock price is above the strike price, while a put option benefits if the stock price is below the strike price.


Expiration Date in Options Trading

Options have a finite life and must be used by their expiration date, beyond which they expire worthless. This date is essential because it impacts the option's value and the strategy you might employ. Shorter expiration periods mean less time for the stock to move favorably, often making these options cheaper but riskier.


In-the-Money, At-the-Money, and Out-of-the-Money

  • In-the-Money (ITM): When the price of the underlying asset surpasses the strike price, a call option becomes ITM.

A put option is ITM if the asset's price is below the strike price.

  • At-the-Money (ATM): When the asset's price is equal to the strike price.
  • Out-of-the-Money (OTM): A call option is OTM if the asset's price is below the strike price. A put option is OTM if the asset's price is above the strike price.

Options Trading Strategies

  • Basic Strategies: Long Call, Long Put
  • Long Call: Buying a call option to profit from an anticipated increase in the underlying asset's price.
  • Long Put: Buying a put option to profit from an anticipated decrease in the underlying asset's price.
  • Advanced Strategies: Spreads, Straddles, and Strangles
  • Spreads: Combining multiple options to limit risk and potential profit.
  • Bull Call Spread: Buying and selling call options at different strike prices.
  • Bear Put Spread: Buying and selling put options at different strike prices.
  • Straddles: Buying both a call and a put option at the same strike price and expiration date, betting on significant movement in either direction.
  • Strangles: Similar to straddles, but with different strike prices for the call and put options.

Risk Management in Options Trading

Risk management is paramount in options trading. 

Techniques include:


  • Position Sizing: Putting a cap on the total amount of money invested in every trade.
  • Diversification: Spreading investments across different assets or strategies.
  • Stop-Loss Orders: Limiting losses by setting predefined departure locations.

Pros and Cons of Options Trading

Benefits of Trading Options
