Bajaj Finance Limited

Has anyone analysed the valuation multiple for BHF? If the company lists at ₹140, representing a 100% premium, it would be trading at a P/B ratio of 6.4 based on the June 2024 book value. No other housing finance company is currently trading at such a high multiple. The market is assigning it a similar multiple to BFL (P/B of 6.04). Is this valuation sustainable?
