We divide the economy into 9 distinct sectors. To create a portfolio that is truly diversified, it is important that you have exposure to most, if not all, of the different economic sectors. Within these sectors, there are a whole bunch of specific industries and sub-industries. You may find some more appealing than others. If you’re looking for more exposure to a certain sector and want to learn more about the different industries within that sector, use this section as a reference. We lay out all of the main industries in each sector, along with short descriptions and examples of stocks found in each one.
