Strike price意思

"Strike price" is a term used in the context of options trading, particularly in the financial markets. It refers to the price at which the underlying asset of an option contract can be bought (in the case of a call option) or sold (in the case of a put option).

In other words, the strike price is the price at which the option holder has the right to enter into a transaction for the underlying asset, if they choose to exercise their option.

For example, if you have a call option on a stock with a strike price of $50, you have the right to buy that stock at $50 per share, regardless of the stock's current market price, as long as the option is in-the-money (i.e., the stock price is higher than the strike price).

Similarly, if you have a put option on a stock with a strike price of $50, you have the right to sell that stock at $50 per share, regardless of the stock's current market price, as long as the option is in-the-money (i.e., the stock price is lower than the strike price).

The strike price is an important factor in determining the value of an option, as it affects the potential profit or loss that can be made from exercising the option.
