The minimum trading unit for HK stocks is “1 lot”, which may equal 100 shares, 500 shares, 1,000 shares, 2,000 shares, etc., depending on the stock price. For example, 1 lot is equal to 100 shares for Tencent Holdings Ltd and 500 shares for BYD AUTO. Where shareholdings are less than 1 lot, it is called “odd lot”.
