Pulling up at the end of the session means that there is a big order to buy, and it may be bullish on the stock on the next trading day. After buying at the end of the day, it can be sold after making a profit on the next trading day, but it does not rule out the possibility of falling on the next trading day after the end of the day. The late rise may also be based on some good news or related large sums of money, which will make investors see the possibility of rising, leading to an increase in stock price buying and a rise in stock price.
