Why do industry averages matter?
The pervasive effect of reversion to the (industry) mean is stronger than many good competitive positions as barriers to entry tend to get broken down. On the positive side, terrible businesses generally get a break when better management comes in. Terrible industries profit when raw materials become cheaper or technology makes capex less burdensome. As a result both negative and positive ROIC’s tend towards their cost of capital.
Extrapolating a firm’s current margins and asset turnover is a capital mistake.
