LONDON/HONG KONG (Reuters) – As HSBC (HSBA.L) prepares to decide which country it should call home, a growing number of its investors want the bank to address a bigger question: what does it really want to be? HSBC’s board is due to meet later this month and is expected to discuss whether it should quit its UK headquarters and shift overseas, with Hong Kong seen as the most likely alternative. If the former is the case, London – as a major financial trading center with a favorable time zone – is the more obvious choice, some say.
