Northern International (000065): The stock price of Northern International also saw a significant increase before shipment. On February 11, 2009, the stock price of Northern International quickly rose after opening. Faced with this rapid upward trend, investors will inevitably actively participate. Therefore, during the process of rising stock prices, there were dense signs of amplification in trading volume. Due to the enthusiastic buying of investors, opportunities were created for the main force to sell, so the main force took the opportunity to sell their chips. Due to the selling pressure of the main force and the rapid rise of stock prices in a short period of time, the stock price has fallen rapidly, and the trading volume has also significantly shrunk, indicating that investors' enthusiasm for participation has significantly decreased during the process of stock price decline. The decline in trading volume has brought inconvenience to the main players' shipments, so how can we attract investors to enter and operate again? There is a way to attract more investors to enter and operate as long as the stock forms a strong upward trend again. So the main force intentionally controlled the stock price to perform a strong consolidation at the average price line, making investors feel that the stock price was a normal consolidation caused by a rapid upward trend in a short period of time, and consolidation would still lead to a strong upward trend in the stock price. The main force utilizes the mentality of retail investors to carry out shipment operations. Indeed, after a strong consolidation above the average price line, the stock price has once again increased in volume and then made another strong consolidation to attract more buying orders. Due to investors having gained their first 'experience', there were constant buyers during the stock price consolidation. In addition, the main force intended to raise the stock price to attract investors, so the stock price quickly hit the daily limit up. From the chart below, we can see that as the stock price approaches the limit up, the trading volume once again increases intensively, reaching the highest volume during the trading session. This indicates that the main force's selling effect is very good. When the stock price is locked at the limit up, if the main force does not want to sell, the trading volume on the limit up board should become smaller and smaller. However, after the stock price reaches the limit up, there are signs of increasing trading volume, indicating that the main force is secretly selling. The reason why the volume cannot be increased may be that the main force holds more funds and is afraid of causing market panic and causing trouble for the main force's future shipments. At the same time, it also indicates that the stock price will still have a high point in the later stage. From the perspective of turnover, the main force will repeatedly fluctuate and increase shipments in the later stage. However, the main force has already started to sell, and investors should pay close attention to it. Figure 4

Figures 5 and 6 show the time charts of Northern International's main shipments using the daily limit up method on February 12 and 13, 2009, respectively.

Figures 7, 8, and 9 show the main shipment charts of Northern International on March 10, 11, and 12, 2009, respectively. Friends have seen the trend of the stock in the later stage. Currently, due to the significant increase in stock price, no one dares to chase after it. Therefore, the main players are unable to sell their chips as they wish for the time being. In the later stage, they can only slowly find ways to sell, and the length of time is related to the main players' holding amount. It cannot be ruled out that there is still a possibility of a rise in the later stage, but the purpose is still to sell.
