Well I have not been a big fan of IT companies in India whether it's about working for them or investing in their stocks for long term. The recent run up in stock prices of TCS, HCL Tech, Tech Mahindra and other IT staffing companies has only increased my worries as they are being perceived as technology companies and getting valuations accordingly.
TCS is now valued at around $90 billion in market value and is trading at a PE of 21 times FY-16 EPS. If one believes that TCS is an innovative technology company like Apple, Oracle or Google then the valuations are justified but what PE would you apply to an employment agency who has just grown at the rate of growth in number of employees in the company. With employee billing arbitrage gradually getting narrowed due to very high wage inflation in India and less than 2% wage inflation in western world the margins will gradually decrease over next 10 years on this business model.
