What is Strike Price in Options? Meaning and Examples

The strike price is the fixed price at which a call or put option can be exercised on or before its expiry date.

In the case of a call option, the strike price is the amount at which the underlying asset can be bought. Conversely, for a put option, it is the price at which the asset can be sold.

On the expiration date, the strike price at which the option is exercised is referred to as the “exercise price.” This price plays a key role in calculating profits, losses, and the breakeven point for any options trade.

While the strike price remains constant throughout the life of the option contract, the market price of the underlying asset fluctuates. Therefore, the difference between the stock price and the strike price determines the option’s “moneyness,” regardless of whether it’s a call or put option.

This article delves into the meaning of strike price, its role in options trading, and the factors that influence it.

Understanding Strike Price in Options

In the world of finance, options are contracts that grant the buyer the right—but not the obligation—to buy while the seller must honor the contract if the buyer chooses to exercise their option at a predetermined price within a specified timeframe. This predetermined price is referred to as the strike price. The underlying asset could range from stocks and commodities to indices.

Strike Price vs. Spot Price

The strike price is the agreed price at which the underlying asset can be bought or sold, while the spot price represents its current market value. Regardless of the spot price fluctuations, the strike price remains fixed as per the contract terms.

Example:

Imagine a stock currently trading at ₹100. A trader anticipates the stock price will rise above ₹120 within a week. Another market participant offers a call option with a strike price of ₹110 at a premium of ₹3. If the stock price rises to ₹120, the trader exercises the option to buy at ₹110 and sells in the market at ₹120, gaining ₹7 (after accounting for the ₹3 premium). Conversely, if the price falls below ₹113, the trader incurs a loss limited to the premium paid.

Strike Price in Put Options

Put options allow traders to sell an underlying asset at a predetermined strike price. The buyer of a put option pays a premium to gain this right.

For instance, if a seller offers a put option with a strike price of ₹110 and the spot price falls to ₹100, the buyer can sell the asset at ₹110, profiting from the price difference after deducting the premium.

Key Factors Influencing Strike Price

The selection of a strike price depends on multiple factors, including:

1. Risk-to-Reward Ratio
   Traders evaluate the potential gains relative to the risks involved before deciding on a strike price.
2. Implied Volatility
   High volatility often increases the likelihood of profitable trades, prompting traders to choose strike prices based on market projections.
3. Liquidity
   Highly liquid options contracts with smaller tick sizes and extended timeframes offer flexibility, encouraging traders to opt for such contracts.

What Are Multiple Strike Prices?

While an individual options contract features a single strike price, traders often employ strategies involving multiple contracts with varying strike prices. This diversification aids in managing risks and maximizing returns.

Strike Price vs. Exercise Price

Though often used interchangeably, there is a subtle difference between these terms. The strike price refers to the price specified in the contract, while the exercise price comes into play only when the option is executed.

Conclusion

A clear understanding of the strike price is essential for successful options trading. As a critical component of the decision-making process, it helps traders evaluate risks and rewards effectively.
