Does value creation vary more within industries than across them?
Core argument: Return on invested capital varies more within industries than across them over 1963–2023, underscoring that industry is important but does not dictate a firm's destiny.
Industries that create value in the aggregate nonetheless have companies that have neutral and negative [return on invested capital (ROIC) vs. weighted average cost of capital (WACC)] spreads. And industries that destroy value in the aggregate still have companies that create value. Exhibit 40 shows ROIC by industry from 1963 to 2023. There are a couple of important takeaways. First, the variance within industries is greater than the variance across industries. This underscores that the industry is important but does not dictate a firm’s destiny. All industries have companies that create and destroy value. The second takeaway is that adjusting ROIC for intangibles tends to pull the very high and very low ROICs toward the middle. The median and average ROICs are similar for both the traditional and adjusted calculations, but the distribution has less variance following the modifications.
