The valuation discount of multi-segment firms in Australia

Abstract

This paper refines the Berger and Ofek (1995) methodology to estimate the valuation discount of multi-segment firms in Australia between 1988 and 1998. Evidence is found that based on earnings before tax, the sample of multi-segment firms traded at a 29 per cent greater discount than a comparable portfolio of single segment firms over the sample period. To explain the results further analysis shows that the valuation discount was driven by poorly performing multi-segment firms rather than multi-segment firms per se. This raises questions about studies that conclude that diversification is value destroying.
