Expanding the market volume is generally a signal that the main players in the market are starting to flee. If investors are indeed interested in stocks with high trading volume, they should wait and take a look. They can draw a straight line on the closing price of the day of high trading volume. If the price hits this line in the future, they can consider buying. 2、 Never buy stocks that have skyrocketed. If a stock market is like a chopstick, soaring to the sky, it means that the market maker has already changed their position and left. If you enter again, you will be trapped. The surge is driven by large funds. When a stock rises to 300% or even higher and the original market main force withdraws and runs away, a new market main force will not form quickly. Usually, there are not many large buying orders to take over immediately, and the price is difficult to rise in the short term. 3、 Never buy stocks with major issues. Those who are seriously dealt with by the management will not enter first. If there is a significant increase in problematic stocks, it can be assumed that institutions are speculating. However, these stocks may face regulation or capital chain breakage, with huge risks. Following them can easily lead to failure, and retail investors cannot control them. It is not worth taking risks. 4、 We will resolutely not buy stocks that have been consolidating for a long time. This type of stock is usually one where the market maker has withdrawn their holdings but has not yet taken all their chips. When looking at a stock, one should look at its continuous trend, and those that have been consolidating for a long time without significant fluctuations should not be bought. 5、 We firmly refuse to buy stocks that are publicly beneficial. This is currently the most common misconception among investors. Even if the performance cannot be better, all Chinese investors can see and buy in, who can make money Moreover, performance can be artificially created. There is a famous saying in the market: "Good news that everyone knows is definitely not good news; bad news that everyone knows is definitely not bad; when all bad news is released, it is good news, and when good news is released, it may drop sharply.
