1. What Are US Stocks, A-Shares, Hong Kong Stocks, Japanese Stocks, and European Stocks?
1.1 US Stock Market
The US stock market is one of the most important equity markets in the world and is primarily centered around two major exchanges: the New York Stock Exchange (NYSE) and the Nasdaq Stock Market. It is home to many of the world's most innovative technology giants, financial institutions, and biotechnology companies, such as Apple, Microsoft, and Nvidia, making it a core hub of the global capital market.
Key features of the US stock market include the dominance of institutional investors, high pricing efficiency, strong disclosure requirements, and a mature regulatory framework. Its trading rules are also highly flexible, with support for T+0 trading and a well-developed short-selling mechanism. In addition, the US market leads the world in both market depth and liquidity. Through MEXC's partner licensed broker, investors can directly buy real shares of US-listed companies and participate in the growth of some of the world's top businesses.
1.2 Japanese Stock Market
The Japanese stock market is represented by the Tokyo Stock Exchange (TSE), with the Nikkei 225 serving as one of its best-known indexes. It is one of the largest stock markets in Asia and also one of the world's major mature markets.
Japanese stocks are characterized by a strong mix of traditional manufacturing and advanced technology industries. Sectors such as automobiles, electronics, and precision instruments are globally competitive. Trading is typically done in units of 100 shares, and the market is heavily influenced by movements in the Japanese yen. Foreign investors also play an important role in the Japanese stock market. In recent years, improvements in corporate governance and stronger shareholder return awareness have attracted growing interest from international investors.
1.3 A-Share Market
A-shares refer to stocks listed on the Shanghai Stock Exchange and the Shenzhen Stock Exchange and traded in RMB in mainland China. The A-share market mainly serves domestic Chinese companies and is one of the world's major emerging markets.
The A-share market is known for its high level of retail investor participation. Market sentiment and policy direction often have a significant impact on stock prices. It follows a T+1 trading system and applies daily price limits, which are generally ±10% for the main boards, ±20% for registration-based ChiNext and STAR Market stocks, and ±5% for ST stocks. In recent years, with the deepening of registration-based reforms and continued internationalization, the A-share market has been moving toward greater maturity.
1.4 Hong Kong Stock Market
The Hong Kong stock market serves as an important bridge between mainland China and global capital. Its main exchange is the Hong Kong Stock Exchange (HKEX). The market includes many high-quality mainland Chinese companies, such as H-shares and red-chip stocks, as well as international firms, giving it a high degree of internationalization.
Hong Kong stocks follow a T+0 trading system and have no daily price limits, but trading is conducted in board lots, with lot sizes varying by stock from 100 shares to several thousand shares. Trading costs, including stamp duty, are relatively high. The Hong Kong market is also known for its many high-dividend stocks. It is strongly influenced by international capital flows and is generally more volatile than some mature markets.
1.5 European Stock Market
The European stock market includes multiple exchanges such as the London Stock Exchange (LSE), Euronext, and the Frankfurt Stock Exchange. Together, they form one of the world's major capital market clusters.
European stocks are dominated by traditional industries such as finance, industrials, energy, and luxury goods. Representative companies include Nestlé, LVMH, and Volkswagen. European equities generally trade at lower valuations and place greater emphasis on steady operations and shareholder dividends, with dividend yields often higher than those of US stocks. At the same time, the European market is structurally more complex because it is influenced by different national policies and monetary frameworks across multiple countries.
