An option contract is a financial derivative. It is a legal agreement that works at a fixed rate called “strike price” for a limited time frame. In this consent, the buyer has an option to buy or sell an asset, and he has to exchange some money for a guaranteed option. The unique part of this contract is that the property under the option contract frame can not be purchased or sold to another member until a specified time is up. The option contract can apply in the real estate industry, where buyers can buy or sell any property.

Option Contract at a Glance

An options contract is a financial service where the seller sets an option for buyers to buy any commodities within a decided time and at a fixed price rate. The buyer is not forced to buy or sell, but he has an option regarding underlying securities.

In an options contract with legally acceptable terms, the seller has no right to cancel the contract after accepting money in terms of exchange. The real estate transactions also use an option contract for their business. Here, a buyer can investigate a particular property to buy before other steps. A deal is done when the buyer agrees to the terms and conditions regarding the consent.

The end period of the contract is a time limit up to the specified time given in the agreement.

Option Contract’s Working

Three many terms associated with an option contract are:

  1. The expiry date of the option contract.
  2. The strike price.
  3. Fundamental assets.

Option agreements typically specify that you can buy call choices as leveraged bets on the value of stocks. On the other hand, you usually buy put options for profit as the prices fall. Option buyers can purchase shares with calls, but they can only buy the amount covered in a contract for a fixed strike price. The opposite also occurs: Buyers have an opportunity to sell (not the obligation), but they can only sell shares at an agreed price.

Call options can be purchased as an advantage of inventory thankfulness. The Call option buyers can buy any underlying asset with the set amount at the contract’s start, but they are not obligated.

Put option buyers are the ones who want to make a profit with decreased prices. The buyers of the put option contract can sell their assets at a fixed price at the start of the agreement, but they are also not bound to do this.

This option contract works against those stockpiles that are unpredictable, and it allows shareholders to speculate or hedge against them. The positive point of the option contract is it costs a minimal amount that stocks are costing themselves.

Option Contract Risk Measurement

The option contract uses the term GREEK to determine dimensions related to the risk for taking an option position or portfolio position. The variables that represent option contracts are related to Greek symbols. An incorrect hypothesis is the outcome of the risk variable linked with another variable.

Investors use a variety of greek signs to check and manage options.

  1. These Greek signs are delta, theta, gamma, vega, and rho.
  2. Delta determines the rate of $1 of an asset and option price.
  3. Theta defines the change of time and the associated cost.
  4. Gamma detects the rate of change of $1 of the delta option and its price.
  5. Vega checks options’ value and implied volatility of an asset’s price.
  6. Rho determines the 1% change rate of the option’s value and interest.


It determines the change price of $1 in an underlying security and an option price. Call option range between zero to one delta, whereas the put option has a zero to negative one value range. For instance, someone invests at 0.50 delta for the call option transaction, and if the price increases to $1, he gains a profit of 50 cents. Investors can also create a delta-neutral option for trading. It also denotes the hedge ratio. For example, the 0.40 standard American call option requires the sale of 40 shares of the stockpile to be a hedge. Option’s portfolio net delta can also be used to obtain the portfolio’s hedge ratio.


The rate of time change concerning price is determined by theta. It is also known as the time decay of an option. An option price is directly proportional to expiration time, and other things are equal, specified by theta.


It is also known as second-derivative. Gamma determines the rate of change of $1 of the option’s delta concerning the price of an asset. It also influences the stability of the delta option. For example, if a long call option has a delta of value 0.50 and a gamma of value 0.10, it will be increased or decreased by 0.10 if there is a rise or low in $1.

Gamma has less influence on delta when options have an extended expiration date and vice versa. Therefore, Delta gamma neutral will require both delta and gamma investment. That means the delta will be near zero if prices move slightly.


It is the rate of change of the option’s value and the implied volatility of an asset with a 1% change. For example, a 1% alteration in implied volatility increases 10 cents of vega if the option value of vega is 0.10.


Rho determines the 1% change rate between the option’s value and interest. For instance, the call option price is $1.25, and its rho is 0.05. It will increase to $1.30 if the interest rate increases by 1%. For a put option, it is the opposite of the call option. Long time expiry with at-the-money has high rho value.

Minor Greeks

Greeks also have their second or third derivatives. These are lambda, vera, speed, zomma, color, epsilon, and ultima. These symbols can be used in trading options for strategy building. They are operating in special software to detect complex risk factors concerning these.

Types Of Options Contracts

The options contract has two major types. These can be call options and put options.

Call Options

A call option can be defined as allowing the buyer to buy an asset at a fixed price within the given time. If the cost of the acquisition increases, the financier buys calls, and if the price goes down, they go for selling calls.

Put Options

A put option is for buyers to sell their assets at a specified price within the stipulated time frame. The investor puts buyers when asset price goes up and sellers when prices decrease.

Pros And Cons Of Call And Put Options


  1. Call option buyers can purchase a stock lower than the market.
  2. The put option buyer can benefit by selling at a strike price, that is, the amount that is lower than the market’s strike price.
  3. A fee has been given to the option seller from the writer for a draft.


  1. If a market is down, the put option seller has to buy the stocks at a higher strike price.
  2. High stock prices can put call option writers in a risky position as they are forced to buy the stock at a higher price.
  3. A minimum fee has to be paid to the writers from option buyers.

Uses Of Options Contract

In the finance and real estate world, prices always go up and down. The option contract can be helpful for these industries. This consent seems intricate, but it helped many sellers and buyers according to their terms.

For example, an investor wants to invest in a clothing industry whose share is $2 each. However, he still wanted to do some research on his behalf about the company shares, so he paid 2 cents per share with a promise to buy the same amount for the next three months. If he cannot complete this project, it is a breach of the contract.

After a couple of days, you find that the company you are searching for is featured in a renowned magazine. The stock price of this featured company went to $50 from $2. You have an option contract agreement with this company, and you can still buy those shares only for $2. The total amount you spent is $2.02 per share. If you start your own company, you can take advantage of this option contract. This contract allows employees to buy the company’s stock at a low price.
