Firms with central or well-connected boards of directors earn superior risk-adjusted stock returns. Initiating a long position in the most central firms and a short position in the least central firms earns an average risk-adjusted return of 4.68% per year. Firms with central boards also experience higher future growth in return-on-assets (ROA) with analysts failing to fully reflect this information in their earnings forecasts. Return prediction, growth in ROA, and analyst forecast errors are concentrated among firms with high growth opportunities or firms confronting adverse circumstances, consistent with boardroom connections mattering most for firms that stand to benefit most from the information communicated and resources exchanged through the network of board members. Overall, our results suggest that board of director networks provide economic benefits that are not immediately reflected in stock prices.

We examine how the information produced by analysts when they initiate coverage contributes to the mix of firm-specific, industry-, and market-wide information available about the firm. We hypothesize that the first analyst to initiate coverage provides low-cost market and industry information allowing him/her to follow more stocks, whereas subsequent analysts provide firm-specific information to distinguish themselves from existing analysts. We use stock return synchronicity to measure the mix of information available about a firm, with higher synchronicity indicating more industry and market information. Coverage initiations of firms with no prior analyst coverage increase synchronicity, suggesting that analysts produce industry- and market-wide information. In contrast, analysts initiating coverage on firms with existing coverage appear to focus on producing firm-specific information as these initiations lead to reduced synchronicity. Together, our findings indicate that the type of information that analysts produce at initiation depends on the information provided by other analysts. Data Availability: All data are available from public sources identified in the paper.
