Do investors actually value sustainability indices? Replication, development, and new evidence on CSR visibility

Abstract

Abstract Research SummaryIn this study, we replicate and expand Hawn et al.’s study (Strategic Management Journal, 2018, 39, 949–976) that used Dow Jones Sustainability World Index (DJSI) events to measure variations in firms' Corporate Social Responsibility (CSR)‐activism and examined their effect on a firm's stock price. We use DJSI events to capture variations in firms' CSR visibility, holding CSR activism constant by restricting our analyses to CSR‐equivalent firms. First, we find similar results on stock price (i.e., no impact) and on trading volumes. Second, because professional market participants pay more attention to CSR‐oriented firms and use visible cues such as DJSI events, we study and find that additions to DJSI lead to more analysts following a firm, and that continuations on the DJSI lead to an increase in equity being held by long‐term investors. Managerial SummaryWe replicate and complement a recent study that showed that the events of a firm's addition, continuation, or deletion in a major sustainability index (DJSI) had little impact on stock market reactions (Hawn et al. Strategic Management Journal, 2018, 39, 949–976). We redefine the comparison set that was previously used and compare across observationally equivalent firms in terms of CSR orientation in order to isolate the visibility effect of DJSI events. We find that these events do not significantly impact stock price and trading volumes. However, we expand the analysis and find that sustainability events attract more attention from financial analysts and lead to an increase in the percentage of shares held by long‐term investors indicative of a trend that professional investors pay more attention to CSR‐visible firms over time.
