I am working on retire early assignment. It is a trading application.... I have gone through lot of trading sites, have not been able to come to a conclusion about what this Holding entity actually means. does this Holding means Portfolio. I know we have to list all our assumptions. But is it right to assume something in business domain itself. I do not think do.can someone worked in this domain area shed a light on this. I accnot make headway with this.

It is ok to make assumptions about the business domain as long as you aren't simplifying the problem.
