I've got Bsc Business Management and I want to study my masters in something relating to Investment, Risk Management, Insurance, and Information Technology. Has anyone got an idea of a course I can do that will be beneficial for me in future. Institutions in London will be preferred.

Depends what you want to go into i suppose. If you wanted to go into investment banking, don't bother doing a masters. I can't help with the rest. I think you need to carefully consider the few areas you could see yourself going into. Then, look at these careers and see if a masters is really needed. Get help from a careers service centre.
