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.

The analysis of an industry’s life cycle is useful for making projections about profit margins, earnings growth, trends in sales and profitability. To simplify things it is quite common to reduce the entire life cycle of an industry to 5 stages Such a 5-stage model is described by Reilly and Brown (2003). Abrief description of the different stages will follow next.

Pioneering development: A modest sales growth is accompanied by small or negative profit margins and profits. The firms face high R&D costs. Most recent examples are high-tech companies or internet-based companies with unproven business models. Most of the financing is obtained through venture capital or private equity.

Rapid accelerating growth: Demand for products and services grows and due to only few competitors, profit margins are high. Firms experience substantial backlogs and production capacity is being built up. At this stage successful companies will be able to access the capital markets for further financing.

Mature growth: An increasing number of competitors enter the market. The demand for the industry’s goods and services is satisfied, prices decline and profit margins begin to decline. At this stage financial discipline is important because future earnings might be lower due to competition. Companies with sustainable debt levels will benefit in the long run.

Stabilization and market maturity: The growth rate of the industry declines to the growth rate of the aggregate economy and profit growth will vary by industry due to different competitive structures. Competition will result in lower profit margins. In this stage industry trends will contribute to the development of aggregate credit quality.

Deceleration of growth and decline: Sales growth declines because of changes in demand and new substitutes. An increasing number of companies start to generate losses. The industry experiences a negative credit trend.
