What is an option?

An option is a right. For example, if you buy a house and it is worth 1 million in June, and you think it will rise in three months, but you only have 50,000, you can use 50,000 to buy the right to buy and sell the house for the next three months. Three months later, if the house rises to 1.2 million, then because you have the three-month call option on the house, the profit you get is 120-100-5=15. With the three-month option on the house, you earn 150,000. But if the value of your house is less than or equal to 1 million after three months, your loss is the 50,000 you bought the option for.
