Strike Price
What Is a Strike Price?
The strike price is the predetermined price at which the holder of an options contract can buy or sell the underlying asset. The strike price is specified in the options contract and remains fixed throughout the life of the option.
The profitability of an option often depends on how the market price compares to the strike price.
Why It Matters
The strike price determines whether an option is profitable, unprofitable, or worthless at expiration. Investors evaluate strike prices when selecting options contracts to align with their expectations for market movement.
Understanding strike prices is essential for options trading strategies.
How Strike Prices Work
When trading options, investors choose contracts with specific strike prices.
For example:
- call options benefit when the market price rises above the strike price
- put options benefit when the market price falls below the strike price
The relationship between the market price and strike price influences the option’s value.
Example
An investor buys a call option with a strike price of $100. If the stock price rises to $120, the option may increase in value because the investor has the right to buy at $100.
