Portfolio Interrelationships and Financial Performance in the Context of European Firms

The linkage between the interrelationships of a firm’s lines of business and corporate financial performance has been the subject of extensive research in the strategy field. Yet very little research has examined this key relationship within firms operating in Continental Europe. This study investigates firm relatedness and its further relationship to accounting and market-based performance measures within a sample of European firms. The results confirm a positive and significant relationship between resource-based relatedness and firm performance for German, Swiss and Austrian multi-business firms. Thus, this study provides further evidence that resource-based relatedness of large diversified manufacturing companies can help explain variability in corporate financial performance across different institutional environments.
