John Mason of SeekingAlpha.com reviewed The End of Competitive Advantage, by Rita Gunther McGrath, published by the Harvard Business Review Press in 2013.
I like to think of myself as a “value investor.” That is, I believe that I invest in quality companies that are underpriced. In terms of the quality of the organizations I like to invest in, I look for firms that have established a competitive advantage in their industries and are earning at least a 15% return on equity, after taxes. To judge the quality of management and its staying power, I look for those organizations that have a sustainable competitive advantage, defined as earning a 15% return on equity, after taxes, for a period of five to eight years. And, to capture the fact that a stock may be underpriced, I look for a low price/earnings ratio.
Other factors that have been important in my analysis are the industry share the company achieves and protects and the stability of this share over time. Of course, these are the quantitative factors and must be supplemented by other factors, such as an examination of management, industry make-up, and governmental factors that might contribute to firm performance.
Well, starting right here, Dr. McGrath starts to eat away at this picture. For one, she argues that industry boundaries are no longer that important. She argues that “arenas” are more crucial in the modern environment. The important thing in today’s world is that there are connections between “the outcomes that particular customers want (the jobs to be done)” and “the alternative ways those outcomes might be met” (page 10). Industry lines are not the determinants of what products one should be producing and what markets they should be sold in. Thus, don’t just look to the competitors that fit nicely into the definitions of what a particular industry does. To read the entire review, click here, and register on the site.
