What is the reason why the stock notified the day before rose well the next day?

This kind of short message usually refers to what their members bought at the end of the day, but it must be closed every time it is sent to you. In fact, they don't have any members, let alone any late acquisitions. But how can they predict which stock will soar tomorrow? In fact, after the close every day, many institutions will make plans for which stock will open higher tomorrow. This kind of information about high opening is actually not difficult to obtain. After they got this information, they said that many funds will go up tomorrow, so let's pay for membership! However, they don't know which stock will open higher at the close tomorrow. They won't know until after the close, and they can only buy it tomorrow. We can't buy the stock at a low price when it opens tomorrow. That stock will be directly opened higher by the organization, and all we can buy are stocks that have risen to the top!
