Call put什么意思

"Call" and "put" are terms used in the context of options trading in the financial markets. Specifically, they refer to two types of options: call options and put options.

A call option gives the holder the right, but not the obligation, to buy a certain underlying asset at a specified price (the strike price) on or before a certain date (the expiration date). The buyer of a call option hopes that the price of the underlying asset will rise above the strike price, allowing them to exercise the option and buy the asset at a lower price than the current market price.

A put option, on the other hand, gives the holder the right, but not the obligation, to sell a certain underlying asset at a specified price (the strike price) on or before a certain date (the expiration date). The buyer of a put option hopes that the price of the underlying asset will fall below the strike price, allowing them to exercise the option and sell the asset at a higher price than the current market price.

In summary, a call is an option to buy, while a put is an option to sell.
