Investors reap greater profits when trading stocks of firms with more connected boards
Companies could benefit from director networks because connected directors might divulge information they heard as members on other boards. Of course, that also means things spoken of in your boardroom might be part of the human capital those directors can use on other boards. Yet an expert says it's entirely possible that the corporation that hires a highly connected director gets more benefit from that director than what it might lose in information leaking out and hitting the market a little bit early.
