Harald Rubner: Corporate Portfolio Management

rubner_harald_thumb_lgHarald Rubner is a senior partner and managing director in BCG’s Cologne office. He is a core member of the Energy and Corporate Development practice areas. He joined BCG in 1993 in the firm’s Düsseldorf office.

Harald has been a BCG Fellow since 2008. His research topic is corporate portfolio management (CPM).

CPM is at the heart of corporate strategy, and it is currently high on the corporate agenda. Changing industry structures, ongoing pressure to focus a firm’s activities, increasingly efficient M&A markets, and the constant chase for value-creating growth opportunities have all brought the corporate portfolio to top management’s attention. Moreover, both activist shareholders and the growing activities of private-equity firms and hedge funds are challenging boards to review their portfolio strategies.

At the same time, many companies realize that their established portfolio-management concepts do not provide answers to some of their most pressing strategic questions. New challenges require new concepts, and a lot of innovation has taken place in recent years.

Harald has led a broad range of strategy assignments in the energy and industrial goods sectors and with private-equity firms. He has a particular interest in transaction costs, portfolio management, and dynamic strategies.

Harald holds degrees in engineering from the RWTH Aachen and in economics from the University of St. Gallen. He earned his doctorate in new trends in value chain architecture and transaction costs.
