What does the term "strike price" refer to in options trading?

In options trading, the term "strike price" specifically refers to the price at which the underlying asset can be bought or sold when exercising an option. This price is predetermined at the time the option contract is created and is crucial in determining the potential profitability of the option.

For a call option, the strike price is the price at which the holder can purchase the underlying asset. For a put option, it represents the price at which the holder can sell the underlying asset. This concept is central to options trading because it helps investors assess whether exercising an option will result in a financial gain or loss, depending on the current market price of the asset compared to the strike price.

The other options do not describe the strike price accurately. The premium refers to the cost of purchasing the option itself, while broker fees pertain to transaction costs rather than the specifics of the option's terms. The market price of the underlying asset is also distinct from the strike price, as it reflects current trading conditions rather than the set price within the options contract.
