英文释义

(1) Calls and puts, as they are commonly called, are types of derivative financial securities, traded privately and on stock markets, which set a fixed price for a stock, bond or other commodity and an expiry date after which the owner of the option can no longer buy the commodity (call option) or sell it (put option). (2)The owner bets that the commodity the option represents will be worth more than the fixed price in the option some time before the call option expires. If it never reaches a worthwhile price, the owner doesn’t have to purchase the commodity, but they lose everything they paid for the option. If it does reach a worthwhile price, the owner can either exercise the right to buy the commodity, or sell the option to someone else willing to exercise the option. (3) Put options function in reverse. In this case, there is a buyer who will purchase the commodity at the predetermined price regardless of whether itsvalue rises or falls, but if the owner of the put option wants to make money, they have to buy the commodity at a lower price in order to resell it at a profit. Owners of put options hope that the value falls, because they can then buy the commodity at the low price and sell to the pre-existing buyer at the higher predetermined price. If the price never reaches an agreeable level for the owner of the put, they can allow the option to expire and not purchase the commodity, and all the owner loses is what they paid for the put. (4) The fixed or predetermined price used in call and put options is referred to as the strike price or exercise price
