Unlike the Australian and US exchanges, The Hong Kong Exchange does not use alphanumeric stock codes. Instead, the Hong Kong Exchange uses solely numerical codes to identify a specific stock.
Examples of these include '700' for the stock 'Tencent' or '1299' for the stock 'AIA'. This differentiates from other markets which use alphanumeric codes such as 'TLS' for 'Telstra' or 'AAPL' for 'Apple'.
When you're searching for a stock using SelfWealth, you do not have to use the numerical code to search for the share. Instead, simply search for the name of the holding (e.g. 'Tencent' or 'AIA') and you will get the same result.
