If you find that your rights and interests have decreased after opening a position in commodity options, there may be the following reasons:
1. option fee: you need to pay the option fee when opening the position. Option fee is the cost of buying or selling option contracts, so your rights and interests will be reduced.
2. Transaction fees: In addition to option fees, transaction fees, including transaction commissions and transaction taxes, are also required. These expenses will also reduce your rights and interests.
3. Price change of subject matter: The value of commodity options is closely related to the price of subject matter. If you buy a call option, that is, you think the price of the subject matter will rise, but in fact the price of the subject matter will fall, then your rights and interests may decrease. On the contrary, if you buy a put option, you think the price of the subject matter will fall, but in fact the price of the subject matter will rise, which will also lead to the reduction of your rights and interests.
4. Time decay: the value of the option contract is affected by time decay, especially the closer to the expiration date, the faster the time decay. If you buy an option contract, but after a period of time, the price of the subject matter has not changed as expected, then your rights and interests may be reduced.
It should be noted that the above are just some common reasons that may lead to the reduction of rights and interests. The specific situation should be judged according to your transaction records and contract terms. If you are confused about the change of your rights and interests, it is recommended to consult a professional financial institution or financial consultant to get a more accurate answer.
