2.         Minimum trading unit and stock price rules for HK stocks

The minimum trading unit for HK stocks is “1 lot”, which may equal to 100 shares, 500 shares, 1,000 shares, 2,000 shares, etc., depending on stock price. For example, 1 lot equals to 100 shares for Tencent Holdings Ltd and 500 shares for BYD AUTO. Where share holdings are less than 1 lot, it is called “odd lot”. For instance, in Tencent Holdings Ltd, 1 lot equals to 100 shares, so if one holds 150 shares of Tencent, then 50 shares thereof become odd lot. Odd lot usually occurs when a company carries out bonus issue or rights issue.
