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.
