Intellectual Property Intensity (IPI) and the Value-Growth Effect

  • Elli Malki

    (Financial-Tip)

Intellectual Property Intensity (IPI) measures the weight of IP in the firm’s total market value. IPI has a positive (convex) functional relationship with Price to Book (P/B) ratio, and thus may provide additional economic insight to the empirical value-growth effect. Growth firms have higher IPI while value firms are characterized by lower IPI. The large (small) weight of IP in growth (value) firms can explain their higher (lower) profitability. This is due to: (i) the monopolistic power that results from IP and (ii) the higher risk associated with IP. Thus, the lower (higher) returns that characterize growth (value) stocks should be attributed to market inefficiency and mispricing and not to lower (higher) risk. The positive bias in growth stock prices is explained by the inability of investors to fully account for the risk associated with IP. Using a sample of biotechnology companies I compare the forecasting ability of IPI versus P/B. I find that IPI has a superior forecasting ability over P/B.
