http://forum.valuepickr.com/t/how-to-analyze-nbfc-companies/5347/24?u=atuld

  1. When to use P/E ratio and when to use Price to Book while analysing NBFCs?

  2. Is it a correct approach to ignore the P/B when company paying the Dividend regularly?

  3. What is the link of above two ratios with respect to RoE? Specially if a company is generating a good RoE (e.g > 25) and healty NIM and low GPA/NPA?

Can someone help in identifying above?

Thanks.
