maybe what you said is different from what I said. But let me say here that in the stock market. Speculation is the main use of some news by those big capital institutions. Raise the price of something that is physical or unnecessary. And the concept. That is to say, the same type of objects that are similar to the hype are combined into a whole.

For example, the first two years are more classic. After the futures are listed. All kinds of vegetable hype. Chinese cabbage that should have been sold in autumn and winter. Because the hype is low. As a result, a large number of Chinese cabbages are all rotten in vegetable fields. Because if you collect it and sell it. The transportation fee is even more expensive than the vegetable price.

and the other one is hyping up the high price. It's what many people have heard of' garlic is cruel'
