Think about all the products that you use every day and who is producing them. These are the companies, which are here to stay. Also think about the material of these products. A product is consisting of many different materials and chemicals. Machinery has to form it maybe. All these are products, too. And with well used products, which you like they might be there to stay. Once a product is there to stay it will be sold well and the company is making continous profits. When you invest in these companies as a shareholder it’s your profit, too.
