Futures are financial products, just like stocks. But it's not the same as stocks.

Stock trading is the ownership of the company (it is only divided into many rights, which is understandable).

Futures trading contract. For example, when rice is ripe next year, if I sell rice, the price will be cheaper because everyone is selling it. Then I set a price with the buyer, write a contract, and agree on the approximate price of the contract next year. This guarantees me a certain profit.

But there may be a flood next year, or a bumper harvest, or the whole market is short of food, etc., and there will be certain risks. Some people just take a fancy to the possible benefits of this risk, so they copy futures. . . .

That's probably what it means.
