The Dark Side of Valuation is a comprehensive guide to valuing technology companies. It begins with an overview of the markets' dramatic shift towards technology stocks. It then identifies key valuation principles and techniques, demonstrating them through five case studies that encompass the entire technology company lifecycle: Amazon.com, Ariba, Cisco, Motorola, and a new IPO-ready startup. This book also covers the adaptation of discounted cash flow models for tech companies with limited histories, shifting business mixes, and volatile stock prices.
