Corporate bond investors should target industries with a balanced business risk and financial risk profile. In mature industries cash flows become increasingly predictable and capital expenditures of companies tend to stabilize.

In such an industry the task is to select those companies who succeeded in controlling their cost structures and operate at efficient levels.

Those sectors will show a stable credit trend. Structural changes might push a whole industry into a declining stage. Companies out of those industries will experience structural losses, hence their credit metrics will deteriorate. Management will have no options available to stop this trend. In a next step the competitive environment of an industry has to be analyzed.

The 5-Forces diagram by Michael E. Porter summarizes best the interaction of an industry with its economic environment. An understanding of those relationships is essential for the projection of credit trends in a sector. The competitive environment determines profit margins and the pricing power of companies.

For a fixed income investor the best investments will be in sectors whose life cycle is in stages 3 and 4. Stage 1 is characterized by high business and financial risk. The rewards can be substantial but fatal losses can occur as well. The traditional financing sources for early stage industries are venture capital, private equity followed by the equity market. In stage 2 an industry will experience accelerating growth in sales and profits, but it can be assumed that all generated funds will be reinvested to grow the business, and financial discipline will not be a priority to management. Bondholder unfriendly corporate actions across the industry will increase the downside potential for corporate bond investors.

Finally, while the subjects of industry analysis and the identification of relative value between sectors are covered in more detail below, it should be noted that the sector allocation has a substantial influence on the risk profile of a corporate bond portfolio. Sectors differ not only with respect to the goods or services they produce, but also with respect to their sensitivity to the economic environment. Therefore, investors usually distinguish between cyclical and noncyclical sectors. In general, cyclical industries are those where the ability to generate revenues and cash flows is closely linked to the business cycle. Usually, this is due to the fact that the companies in those sectors produce goods or services for private consumption or that belong in the category of capital expenditures. Typical examples of cyclical sectors therefore are the automotive and the capital goods sector.
