The basic framework for identification is three-pronged. First, only companies with market capitalization of more than Rs.100 crore are taken. Second, to overcome cyclicality, the time period of analysis is fixed at a decade. Third, superior financial performance is defined here as revenue growth of 10% p.a. and ROCE in excess of 15% for each of the 10 year period. In the case of financial firms, the last criterion has been altered to 15% loan growth and with a ROE in excess of 15%. Mukherjea deconstructs the journey of each of the companies thus chosen and thanks to access to the management and a deep understanding of the equity markets; he is able to come up with a lot of interesting insights. There is information on the formative years, the initial struggle, the strategies, management wisdom and eventually what worked (aptly titled – the secret sauce). The book offers lots of interesting stories, whether it is about Asian Paints’ focus on technology and its hiring strategy of hiring or PJ Nayak's bold decisions on ESOPs or how technology up gradation, capital infusion and branch expansion led to Axis bank being where it is today. What is interesting for the reader is that he can easily identify with the journey and get a real understanding of why these companies succeeded and more importantly what kept them successful over prolonged periods. Towards the end, there is a chapter on value investing checklist and this will serve the relatively new entrants to the value-investing club.
