This study examines company-specific factors that may help explain the choice of an exportmarket strategy and explores how the selected export strategy contributes to explaining company's export performance (XP). Concentrating on a specific area within a broad spectrum of export behavior analysis has enabled us to examine these factors in greater depth. The results of our research, which was carried out using a sample comprising Spanish exporting companies, show a firm's size, a firm's age, and a firm's greater foreign ownership in its share capital are all determining factors for adopting a strategy geared to export-market diversification. A greater level of investment in R&D and greater international commitment are also important in this regard. We suggest reinforcing these two factors because there is evidence of a better XP among firms that have a wider range of foreign markets.
