Finding and tracking what the big institutions and investment houses have been buying into can be a great guide as to what you should look at buying into. Boutique fund managers with a good track record of the stocks they buy into go to a great deal of trouble to research the stocks they buy. They have professionals looking into all facets of the stocks and have access to information and direct contact with the company's directors that small investors just don't have access to. Once they have properly researched a stock and they buy it they are putting their money where their mouth is.
