At the heart of strategic management is the definition of a company’s business unit strategy, which is supported by corporate portfolio management. While the concept of corporate portfolio management, its role within the strategic management process, as well as the corresponding corporate portfolio instruments have been extensively addressed by literature, the communication of corporate portfolio information towards a company's shareholders and other stakeholders has not received in depth research attention yet. This book offers an innovative research approach by creating a concept for corporate portfolio communication including its dimensions, extent and communication, based on which stock market and behavioral CEO antecedents are investigated.
