1. In terms of trading mode. The trading mechanism of A shares is T+ 1, and the current shares cannot be sold on the same day, so they can only be sold the next day. The trading mechanism adopted by Hong Kong stocks is T+0, which can be sold on the day of buying.
2. From the perspective of trading varieties. A-shares include stocks and funds, while Hong Kong stocks include stocks, options, Hang Seng Futures and hedge funds.
3. Price limit. There is a daily limit on the rise and fall of A-shares, that is, the maximum rise and fall in one day does not exceed 10%, and the rise and fall range of risk warning stocks and stocks that have not completed the share-trading reform is 5%, while there is no limit on the intraday rise and fall of Hong Kong stocks.
4. The stock market of A shares is free, and Hong Kong stocks do not provide free information. If you want to view instant messages, you need to pay, and the quotes on financial websites and some trading software will be delayed. A shares rose red and fell green. Hong Kong stocks, like overseas securities markets, are green when they rise and red when they fall.
5. There are other points to understand:
(1) The clearing and settlement of Shanghai-Hong Kong Stock Connect is conducted in RMB, and foreign currencies such as USD are not used. Shanghai-Hong Kong Stock Connect implements the closed path management of funds, and the funds obtained from selling securities must be returned to the original road and cannot be retained in the local market.
(2) Transaction rate: The stamp duty rates of both places are 0.65438+ 0% of the turnover, but the Shanghai stock charges one way and the Hong Kong stock charges two ways. Transfer fees and Shanghai Stock Exchange charge according to a fixed proportion of the number of transactions, while Hong Kong stocks charge according to a fixed amount. The dividend tax in Shanghai stock market is divided into 5%, 10% and 20% according to the holding time, while local enterprises in Hong Kong stocks do not collect dividend tax, while mainland enterprises collect 10%.
(3) The upper limit of the number of stocks declared for a single transaction in Shanghai Stock Exchange is no more than 6,543.8+0,000 shares, that is, 6,543.8+0,000 shares, while the upper limit of Hong Kong stocks is 3,000 shares.
(4) Calculation of closing price. The closing price of Shanghai stock is the weighted average price of all transactions in the last minute (including the last transaction), while Hong Kong stock chooses the median of the five closing prices recorded every 15 seconds in the last minute as the closing price of the stock.
