The Hong Kong Stock Exchange (HKG) is one of the most prominent stock exchanges in the world. It is located in the Central District of Hong Kong, and is commonly referred to as the HKEx. It is the ninth largest stock exchange in the world in terms of market capitalization, valued at over USD$4 trillion. HKG is home to some of the largest and most influential publicly traded companies in the region, such as Tencent, China Mobile, AIA Group, Ping An Insurance, and China Construction Bank.

The Hong Kong stock exchange was founded in 1891, and is the oldest in Asia. It has been a leader in the Asian markets, and has grown tremendously in size. It originally was just a web-based trading platform, and expanded to include physical trading in the '80s.

The exchange features over 2,400 securities, including both stocks and derivatives. These products allow investors to access a large variety of investments and trading opportunities. It is one of the most liquid markets in the world, with high liquidity providing transparency and surety for investors.
