I guess you must understand that stocks are actually spot transactions, with one hand paying and one hand delivering.
Futures, on the other hand, are standard forward contracts, which stipulate the subject matter, quantity and delivery period.
So futures are not specific commodities, but contracts.
The most fundamental difference between futures and spot (stock) lies in the leverage principle margin system (margin).
If the margin leverage is calculated by 10 times, that is,10,000 yuan can be used for business.
Futures are divided into commodity futures and financial futures according to different subject matter.
Commodity futures are easy to understand, and it is a standard order and supply contract with a certain commodity as the subject matter.
Financial futures, such as SSE 300 index futures currently traded in China, are the subject matter of SSE 300 index.
If you think this index will go up or down, then buy or sell this futures contract.
Options are more virtual, buying and selling are neither spot nor futures (forward contracts), but a kind of "right".
For example, stock options, do you think a stock is 5 yuan now, and it may go up in the future?
You can buy a right (pay a fixed royalty), and the content of the right is:
At some point in the future, you have the right to buy a specified number of shares at the price of 5 yuan per share.
You can exercise this right when it expires or you can give it up.
As for whether to implement or give up, you have to understand: of course, if it goes up, it will be implemented, and if it falls, it will give up.
The profit brought by the implementation is the incremental profit of the stock MINUS the royalties paid at the beginning.
So the biggest loss of this operation is fixed, that is, the royalties paid.
