Why this method for this business
The justified P/B and residual income models are most appropriate for a bank with a wide moat and sustainable ROE, as they align with the capital-light nature of banking and the importance of book value and excess returns.
The models behind the number

Who computed this
A language model (qwen3:8b) selects the valuation method and the judgement inputs for AU Small Finance Bank Limited: which models suit the business, the moat, the growth and margin assumptions. It does not produce the number. The fair value itself is computed in Python by a deterministic engine (version 2026.08.1) from those inputs, so the same inputs always give the same result and every figure above can be traced to a source.

How we value stocks
We estimate what a business is worth from its own economics: cash flows, returns on capital, and a multiple justified by its quality, rather than from where the share price has been. A fair value estimate is a view, not a verdict, and it is only as good as the inputs listed above.
