This is the typical principle agent problem, it depends of the ownership of the company. If it is privately hold, then savings make sense and you have to optimize for sustainability, i.e. otherwise your private savings are nilified. But if the company is widely spread by shareholders, then you have the maximize value by concentrating on one product, and leverage by keeping down the risk factor while still maintaining a high enough earnings on capital rate. The risk is adverted by the shareholders themselves that have their own portfolio of companies.
