There are many differences between the Hong Kong securities market and the mainland market, including 1. The Hong Kong securities market is more international and has more institutional investors. The transaction volume of overseas and local institutional investors accounts for approximately 65% ??of the total transaction volume (39% respectively)

and 26%), and the transaction volume of overseas investors accounted for more than 40% of the total transaction volume.

Since investors from various places may make different judgments on securities valuation and market prospects, mainland investors should be more cautious when participating in the Hong Kong securities market.

2. In terms of product types, the Hong Kong securities market provides different types of products, including equity securities, equity warrants, derivative warrants, futures, options, CBBCs, exchange-traded funds, unit trusts/mutual funds, and real estate investment trusts.

Funds and debt securities provide investors with different risk appetites with choices under different market conditions.

There are also many differences in trading arrangements between the two markets. For example: 1. The mainland market has a price limit system, that is, if the fluctuation range exceeds a certain percentage, the relevant shares will stop trading for a specified period of time; the Hong Kong market does not have this system

.

In addition, according to Hong Kong law, Hong Kong's securities and futures exchanges may not suspend trading unless instructed by the Hong Kong Securities and Futures Commission after consulting the Financial Secretary of the Hong Kong Special Administrative Region.

2. In the Hong Kong securities market, when the stock price rises, the color displayed on the stock quotation screen is green, and when the stock price falls, it is red; in the Mainland, the opposite is true.

3. The Hong Kong securities market mainly uses Hong Kong dollars as the trading currency; the mainland stock market uses RMB as the trading currency.

4. In Hong Kong, securities firms can arrange for investors to sell securities that have been purchased earlier on the same day, commonly known as "same-day fresh" trading.

Mainland China requires securities to be transferred into the account before they can be sold.

Investors are advised to discuss with their securities firms whether "same-day fresh" trading is allowed.

5. The Hong Kong securities market allows regulated short selling transactions.

6. Hong Kong’s securities clearinghouse settles securities and clears payments with securities firms on T+2.

All clearing arrangements between securities firms and their clients are commercial agreements between securities firms and investors.

Therefore, investors should inquire with securities dealers about payment settlement arrangements before trading, such as whether immediate payment is required when purchasing securities, or when they can get their money back after selling securities.
