致精进的你:
Hello, i can give you an example to understand this question.You invest $10 in a stock,you will suffer from a loss if the price of your stock drop.In this situation,you can use derivatives to hedge your exposure. Selling a future means that you lock a selling price in $7 when you enter into a contract.If the price of your stock drop to $2 ,you can still sell your stock at $7 when your contract expired.Buying a put option means you believe the price of your stock will drop in the future .When you buy a put option with strike price at $7,you can sell your stock at $7 when the price of your stock drop to $2 in the expiretion date.However,you will lose $8(from $10 to $2)without using hedging instrustments.
