Published: September 16, 2015 at 6:00 pm

Last Updated on

In the 7th version of the automated stock analyzer, two more valuation metrics have been added: The Graham Formula and the Graham Number. Bugs and suggestions made by users have been corrected/incorporated in this edition.

The automated stock analyzer

  • pulls annual (standalone/consolidated) and quarterly financials from Value Research online
  • pulls financials from morningstar and analyzes them, adjusted
  • pulls adjusted stock price history from money control, and
  • calculates intrinsic value six different ways!

Valuation models available:

1) Price Multiple Model

2) Sustainable Growth Rate

3) Book Value Growth Rate (Buffett’s approach to valuation)

4) Discounted Cash Flow (DCF) Thanks to Debasish Hazra  and Ninand Diveakr for pointing out a bug. This is now corrected

5) Reverse DCF Valuation

6) Graham formula  and Graham number

All necessary links for learning each valuation model is provided in the Excel sheet itself. Following the flow of information in the sheet, a new investor should be able to understand how the valuation is done.

Graham Formula:

This uses the EPS, EPS growth rate, the risk-free return and long-term corporate bond yields to arrive at the intrinsic value of a stock.

Graham number:

This is thumb rule valuation that uses 15 times earnings per share and 1.5 times book value.


Note
: I am not a stock investor. I only have an academic interest in stocks and do not have a feel for the limitations of valuation metrics and ‘when’ to use ‘what’.Both these metrics are described in his book, The Intelligent Investor.

Caveats to note before using the sheet pointed out byIndranealBalasubramaium
(1) Financial stocks like banks, housing finance companies and non-banking financial companies have balance sheet structures that are likely to be different from regular companies. Make sure to read the annual report and especially notes to financial statements.
(2) Take the time out to understand valuation models and how they are derived, what the implications are. Precision can give a false sense of accuracy, especially when dealing with an uncertain future. Better to be approximately right than exactly wrong.
