First, stock concentration, or chip concentration, is used to observe whether a stock has a large amount of funds to raise. If the main force buys a stock repeatedly, the chip concentration of the stock will become higher, indicating that the average number of shares held by each shareholder increases and the number of shareholders decreases; On the other hand, if a stock has no main force or the main force has not completed the shipment, then its chip concentration will become lower, indicating that the average number of shareholders per household will decrease and the number of shareholders will increase. The more inconsistent people who participate in stock trading evaluate the stock price, the greater the trading volume. Conversely, the more consistent the evaluation, the smaller the transaction volume. The former means that the long and short sides have great differences of opinion, and the stock price has risen and fallen sharply in the melee; The latter is long and short, the views of both sides are slightly the same, the operation is relatively inactive, and the price rise and fall will be very limited.
Second, judging the stock concentration: judging the equity distribution of chips is the basic premise of stock market operation. If the judgment is accurate, the hope of success will increase a lot. There are several ways to judge the distribution of equity.
1. According to the statements of listed companies, if the capital structure of listed companies is relatively simple, there are only state shares and tradable shares, and most shareholders of the former 10 hold tradable shares. There are two ways to judge: one is to accumulate the outstanding shares before 10, depending on how much you have mastered. This situation is suitable for analyzing the degree of participation of institutions. The second is to guess the situation after 10. Some people think that if the last shareholder holds no less than 0.5%, it can be judged that the chip concentration of the stock is relatively concentrated, but the dealer sometimes practices fraud. He kept the chips of his former shareholders. It is difficult to see the change since then, but one thing is certain. If the shareholder 10 holds less than 0.2% of the tradable shares, it will be lower later, so it can be judged that the concentration is low.
2. The stock market publishes the trading information of stocks with an increase or decrease of more than 7% every day through the public information system, mainly the names and trading amounts of the top five business departments or seats with the largest trading amount. If a stock rises a lot, most of them are concentrated buyers. If the transaction volume drops, most of the announcements are concentrated sellers. This information can be found on the computer or in the newspaper. If the transaction amount of these business office seats also accounts for 40% of the total transaction amount, it can be judged that there is strong access.
