under normal circumstances, a listed company will greatly discount its ex-dividend share price if it implements a high proportion of share delivery and capitalization, but in fact, investors have not suffered losses due to the increase in the number of shares. Ex-dividend and ex-dividend have a neutral influence on shareholders. On the one hand, ex-dividend and ex-dividend can more accurately reflect the corresponding value of listed companies' share prices, on the other hand, it can also facilitate shareholders to adjust their shareholding costs and analyze profit and loss changes.

However, listed companies can increase their total share capital through high proportion distribution and lower their share prices through ex-dividend and ex-dividend, which can improve their liquidity. Listed companies with good stock liquidity are often favored by institutional investors if their performance is excellent, which is an important factor in the implementation of private placement and possible subsequent margin financing and securities lending business.

after the ex-right, if the ex-right is not dealt with, the share price of listed companies will form a big gap, which will cause abnormal changes in K-line and technical indicators, which is not conducive to investors' technical analysis. However, in general stock analysis software, there are options for restoring the K-line, which are divided into pre-restoring right and post-restoring right, and some softwares are lower restoring right and upper restoring right.

The so-called post-right refers to the adjustment of the current stock price according to the price before ex-right, that is, the market data after ex-right is converted back to the price before ex-right, but the stock price trend is coherent, which is convenient for investors to analyze the current profit margin according to the cost before ex-right.
