ABSTRACT
The Nigerian economy is today in dire need of funds from both internal and external sources for investment. These funds are not
forthcoming. The problem is compounded by the fact that expertise in management especially investment menagement is virtually lacking. Perhaps because of the mathematics involved, few people have ventured into the field. The study is undertaken in order to show that an investor could
collect data of almost any security and analyse it, using simple statistical tachniques and see how such a security fares.
He could then form suitable portfolios based on simple guidelines.
He could then decide whether to diversify within or across industries
