(1) Automatic rights recovery means that the stock software automatically judges whether it has the right to be extinguished on that day. According to the comparison between yesterday's closing price and the closing price of the previous trading day received today, if the two are not equal, it can be confirmed that the right is extinguished today, and then the delivery plan is calculated to recover the right. This method has many problems and cannot be accurately restored.
(2) Accurate right recovery is to accurately calculate the right recovery price according to the rights distribution of listed companies, the conversion of reserve funds into share capital, and the rights issue. And the ex-dividend quotation scheme of the exchange. Calculation formula of accurate composite weight:
Before reinstatement: price after reinstatement = [(price before reinstatement-cash dividend)+price of issued (new) shares × change ratio of circulating shares ]=( 1+ change ratio of circulating shares)
After reversion: price after reversion = price before reversion ×( 1+ change ratio of circulating shares)-allotment price × change ratio of circulating shares+cash dividend.
3. In the stock market, reinstatement refers to restoring the stock price and trading volume, drawing the stock price trend chart according to the actual ups and downs of the stock, and adjusting the trading volume to the same equity caliber. After stock ex-dividend and ex-dividend, the stock price has changed, but the actual cost has not changed. For example, the original shares in 20 yuan are 10 yuan after giving away ten shares for free, which is actually equivalent to 20 yuan. Judging from the K-line chart, this price seems very low, but it is likely to be an all-time high. 4. The so-called "reinstatement" is to repair the stock price and trading volume, draw the stock price trend chart according to the actual rise and fall of the stock, and adjust the trading volume to the same equity caliber. For example, a stock circulated 50 million shares the day before ex-dividend, with a price of 10 yuan and a turnover rate of 10%. After 65,438+00 is sent to 65,438+00, the ex-dividend price is 5 yuan, and the circulation is 654,380+million shares. Ex-dividend day out of the stock market, closing in 5.5 yuan, rising. After the reinstatement, the share price was 1 1 yuan, which was 10% higher than the previous day's 10% 0 yuan, and the trading volume was 5 million shares, which truly reflected the stock price fluctuation on the stock price chart, and the trading volume was similar before and after the ex-rights.
