Module 3 Fundamental Analysis

Chapter 12

The Investment Due Diligence


12.1 – Taking stock

Over the last few chapters we understood how to read the financial statements and calculate a few important financial ratios. These chapters have laid the foundation to the final objective of this module which is – To use fundamental analysis to identify the stocks to invest. If you recollect in the earlier chapters, we had discussed about investable grade attributes. Investable grade attributes simply define the prerequisites of a company that needs to be validated before making an investment decision.  Think of the investable grade attributes as a checklist based on the fundamentals of the company. A company that satisfies most of the items in the checklist, is considered investment worthy.

Now this is where few differences come up. For instance, what I consider as an investable grade attribute may not be so important to you. For example – I may pay a lot of attention to corporate governance but another investor may choose not pay so much attention to corporate governance. He could simply brush it off saying “all companies have shades of grey, as long as the numbers add up I am fine investing in the company”.

So the point is, there is no prescribed checklist. Each investor has to build his own checklist based on his investment experience. However, one has to ensure that each item on the checklist is qualified based on sound logic. Later in this chapter, I will share a checklist that I think is reasonably well curated. You could take pointers from this checklist, if you are starting out fresh. We will keep this checklist as a guideline and proceed further in this module.


12.2 – Generating a stock idea

Now before we proceed further and generate a checklist, we must address a more basic issue. The process of investing requires us to first select a stock that looks interesting. After selecting the stock we must subject it to the checklist to figure out if the stock matches all the checklist criteria, if it does we invest, else we look for other opportunities.

So in the first place, how do we even select a stock that looks interesting? In other words, how do we generate a list of stocks that seems interesting enough to investigate further? Well, there are a few methods to do this –

  1. General Observation – This may sound rudimentary, but believe me this is one of the best ways to develop a stock idea. All you need to do is keep your eyes and ears open and observe the economic activity around you. Observe what people are buying and selling, see what products are being consumed, keep an eye on the neighborhood to see what people are talking about. In fact Peter Lynch, one of the most illustrious Wall Street investor advocates this method in his book “One up on Wall Street”. Personally I have used this method to pick some of my investments – PVR Cinemas Ltd (because I noticed PVR multiplexes mushrooming in the City), Cummins India Limited (because I noticed most of the buildings had a Cummins diesel generator in their premises), and Info Edge Limited (Info Edge owns, which is probably the most preferred job portal).
  2. Stock screener – A stock screener helps to screen for stocks based on the parameters you define and therefore helps investors perform quality stock analysis .For example you can use a stock screener to identify stocks that have a ROE of 25% along with PAT margins of 20%. A stock screener is very helpful tool when you want to shortlist a handful of investment ideas from a big basket of stocks. There are many stock screeners available; I personally like the Google finance’s stock screener and
  3. Macro Trends – Keeping a general tab on the macroeconomic trend is a great way of identifying good stocks. Here is an illustration of the same – As of today there is a great push for infrastructure projects in India. An obvious beneficiary of this push would be the cement companies operating in India. Hence, I would look through all the cement companies and apply the checklist to identify which amongst all the cement companies are well positioned to leverage this macro trend.
  4. Sectoral Trends – This is sector specific. One needs to track sectors to identify emerging trends and companies within the sector that can benefit from it. For example the non alcoholic beverages market is a very traditional sector. Mainly, three kinds of products are sold and they are coffee, tea, and packaged water. Hence, most of the companies manufacture and sell just these three products. However there is a slight shift in the consumer taste these days – the market for energy drink is opening up and it seems to be promising. Hence the investor may want to check for companies within the sector that is best positioned to leverage this change and adapt to it.
  5. Special Situation – This is a slightly complicated way of generating a stock idea. One has to follow companies, company related news, company events etc to generate an idea based on special situation. One example that I distinctly remember was that of Cox & Kings. You may know that Cox & Kings is one of the largest and the oldest tour operator in India. In late 2013, the company announced inclusion of Mr.Keki Mistry (from HDFC Bank) to its advisory board. Corporate India has an immense respect for him as he is known to be a very transparent and efficient business professional. A colleague of mine was convinced that Cox & Kings would benefit significantly with Mr. Keki Mistry on its board. This alone acted as a primary trigger for my colleague to investigate the stock further. Upon further research my colleague happily invested in Cox & Kings Limited. Good for my him, as I write this today I know he is sitting on a 200% gain
  6. Circle of Competence – This is where you leverage your professional skills to identify stock ideas. This is a highly recommended technique for a newbie investor. This method requires you to identify stocks within your professional domain. For example, if you are a medical professional your circle of competence would be the healthcare industry. You will probably be a better person to understand that industry than a stock broker or an equity research analyst. All you need to do is identify which are the listed companies in this space and pick the best based on your assessment. Likewise if you are banker, you will probably know more about banks than the others do. So, leverage your circle of competence to pick your investments.

The point is that the trigger for investigating stocks may come from any source. In fact, as and when you feel a particular stock looks interesting, just add it to your list. This list over time will be your ‘watch list’. A very important thing to note here is that a stock may not satisfy the checklist items at a particular time, however as the time progresses, as business dynamics change at some point it may match up to the checklist. Hence, it is important to evaluate the stocks in your watch list from time to time.


12.3 – The Moat

After selecting a stock, one has to run the checklist to investigate the stock further. This is called the “Investment due diligence”. The due diligence process is very critical and one has to ensure maximum attention is paid to each and every aspect of this exercise. I will shortly present a checklist that I think is reasonable. But before that, we need to talk about ‘The Moat’.

Moat (or economic moat) is a term that was popularized by Warren Buffet. The term simply refers to the company’s competitive advantage (over its competitors). A company with a strong moat, ensures the company’s long term profits are safeguarded.  Of course the company should not only have a moat, but it should also be sustainable over a long period of time. A company which possesses wider moat characteristics (such as better brand name, pricing power, and better market share) would be more sustainable, and it would be difficult for the company’s rivals to eat away its market share.

To understand moats, think of “Eicher Motors Limited”. Eicher Motors is a major Indian automobile manufacturer. It manufactures commercial vehicles along with the iconic Royal Enfield bikes. The Royal Enfield bikes enjoy a huge fan following both in India and outside India. It has a massive brand recall. Royal Enfield caters to a niche segment which is growing fast. Their bikes are not as expensive as the Harley Davidson nor are they as inexpensive as probably the TVS bikes. It would be very hard for any company to enter this space and shake up or rattle the brand loyalty that Royal Enfield enjoys. In other words, displacing Eicher Motors from this sweet spot will require massive efforts from its competitors. This is one of Eicher Motors’ moat.

There are many companies that exhibit such interesting moats. In fact true wealth creating companies have a sustainable moat as an underlying factor. Think about Infosys – the moat was labor arbitrage between US and India, Page Industries – the moat was manufacturing and distribution license of Jockey innerwear, Prestige Industries – the moat was manufacturing and selling pressure cookers, Gruh Finance Limited – the moat was small ticket size credits disbursed to a certain market segment…so on an so forth. Hence always invest in companies which have wider economic moats.

12.4 – The Due Diligence

The equity research due diligence process involves the following stages –

  1. Understanding the business – requires reading the annual reports
  2. Application of the checklist and
  3. Valuation – to estimate the intrinsic value of the business

In stage 1 i.e Understanding the business we dwell deep into the business with a perspective of knowing the company inside out. We need to make a list of questions for which we need to find answers to. A good way to start would be by posting a very basic question about the company – What business is the company involved in?

To find the answer, we do not go to Google and search, instead look for it in the company’s latest Annual Report or their website. This helps us understand what the company has to say about themselves.

When it comes to my own investing practice, I usually like to invest in companies where the competition is less and there is very little government intervention. For example, when I decided to invest in PVR Cinemas, there were only 3 listed players in that space. PVR, INOX, and Cinemax. PVR and Cinemax merged leaving just 2 listed companies in that space. However, there are a few new players who have entered this space now, hence it is time for me to re evaluate my investment thesis in PVR.

Once we are comfortable knowing the business, we move to stage 2 i.e application of the checklist. At this stage we get some performance related answers. Without much ado, here is the 10 point checklist that I think is good enough for a start –

Sl No Variable Comment What does it signify
1 Gross Profit Margin (GPM) > 20% Higher the margin, higher is the evidence of a sustainable moat
2 Revenue Growth In line with the gross profit growth Revenue growth should be in line with the profit growth
3 EPS EPS should be consistent with the Net Profits If a company is diluting its equity then it is not good for its shareholders
4 Debt Level Company should not be highly leveraged High debt means the company is operating on a high leverage. Plus the finance cost eats away the earnings
5 Inventory Applicable for manufacturing companies A growing inventory along with a growing PAT margin is a good sign. Always check the inventory number of days
6 Sales vs Receivables Sales backed by receivables is not a great sign This signifies that the company is just pushing its products to show revenue growth
7 Cash flow from operations Has to be positive If the company is not generating cash from operations then it indicates operating stress
8 Return on Equity >25% Higher the ROE, better it is for the investor, however make sure you check the debt levels along with this
9 Business Diversity 1 or 2 simple business lines Avoid companies that have multiple business interests. Stick to companies that operate in 1 or 2 segments
10 Subsidiary Not many If there are too many subsidiaries then it could be a sign of the company siphoning off money. Be cautious while investing in such companies.

Lastly, a company could satisfy each and every point mentioned in the checklist above, but if the stock is not trading at the right price in the market, then there is no point buying the stock. So how do we know if the stock is trading at the right price or not? Well, this is what we do in stage 3. We need to run a valuation exercise on the stock. The most popular valuation method is called the “Discounted Cash Flow (DCF) Analysis”.

Over the next few chapters, we will discuss the framework to go about formally researching the company. This is called “Equity Research”. The focus of our discussion on equity research will largely be on Stage 2 and 3, as I believe stage 1 involves reading up the annual report in a fairly detailed manner.

  1. Prashant Warrier says:

    This is great stuff….Presented beautifully…..The author mentions “equity Research” as the next topics but it doesnt seem to be here…..Is it waiting to be added over time?

    • Karthik Rangappa says:

      Thanks Prashant. Fundamental Analysis is work in progress, there are 4 more chapters pending before we wind up FA. Equity Research (Part1) will be uploaded in a day or 2 I guess. Please stay tuned for more.

  2. kishore says:

    Sir, you mentioned that high P/E stocks must be avoided whatever sector may be. But, you have purchased PVr wchich has high P/E of over 65. Pl. clarify

    • Karthik Rangappa says:

      I picked up PVR around March 2013, when the stock was trading ard 250 sorts. The PE was much lower then. Of course the PE has shot up now, but I would not worry about it for few reasons (1) My investment horizon is quite large (multi year) (2) Even if the stock cracks, I have a reasonable cushion (3) I will stay invested as long as the business moats continue to sustain.
      Needless to say, if I were to buy PVR now, I may not have done so.

  3. t rama says:

    what is EV/EBITDA, how it works in identifying stock. what is EV. Thanks

    • Karthik Rangappa says:

      EV is the enterprise value of the firm. It can be calculated as follows –

      EV = Market Cap of the stock + Debt – Cash. For example Bajaj auto has a market cap of 59239crs, Debt of 57Crs, and Cash if Rs.106crs. Hence EV would be

      = 59239+57-106
      Bajaj’s EBITDA is 4837 Crs

      Hence EV/EBITDA
      =12.23 times

      EV/EBITDA is a valuation metrics. In case of Bajaj Auto example it is telling me that at current price market price of Rs.2037, an investor has to payg 12 times Bajaj auto’s operational income (EBITDA). This can be considered expensive or cheap by comparing with its peer companies. For example TVS Motors is trading at 22.2 times, Eicher is trading 34 times.

      • Akshath says:

        So what is your view? As the EV/EBITDA compare to peers is cheap is it worth investing during march 2015 in Bajaj Autos? From only EV/EBITDA ratio

        • Karthik Rangappa says:

          You cannot invest based on this one ratio alone 🙂

          I’d suggest you look at the business in detail and then make a call on investment.

  4. Geetansh says:

    Sir how to find the intrince value(actual value) of the stock??



    Sincerely appreciate the efforts that you and Team Zerodha are taking to educate retail investors like me. Keep doing the great work. Looks like Zerodha is in a mission with symbiotic values where every one will end up getting profits 🙂

    Thanks Again,

  6. priya says:

    hi karthik,
    I am new to trading, each and very module from varsity is helping me shape my trading strategy. I am more confident day by day. thanks for doing the great work.
    Is it wise for freshers to invest in IPO?

    • Karthik Rangappa says:

      Thanks Priya. Glad you are liking Varsity!

      If the IPO is good then if does make sense to invest in the IPO. But please do make sure that the company qualifies all the required criteria.

  7. Michael Mathew says:

    Were can any one find the order books of a public limited company and how to get AGM and Conference reports?

  8. Vijai says:

    I need to shortlist the stocks using Stock screener in google finance.Please advise what are the criteria worth to be considered?
    I use Beta,Volume,P/E. Is it okay? which is the most important ?

    • Karthik Rangappa says:

      The screener design changes according to the trading requirement. For long term investments I’d look at things like margins, growth, ROE, ROC etc. But for active trading I’d look for support, resistance, indicator values etc.

  9. SAILAJA says:

    Hi Karthik,
    The second point in 10 point checklist, “Net Profit Growth” !! Should it not be “Net Revenue Growth” or “Net Sales Growth”?. It is contradicting with “Revenue growth should be in line with the profit growth” in last column.

  10. SAILAJA says:

    Many thanks for your confirmation and quickly changing it.

  11. Pandit Yogesh says:

    Why and how dilution it is not good for shareholder?

  12. Vishal Saini says:

    Thank you so much Karthik sir for educating all of us here..:)

    Could you elaborate point 6 of checklist “Sales backed by receivables is not a great sign” and also how to check debt level (point 4) ????

    • Karthik Rangappa says:

      Receivables is like a credit sale….wherein you sell your goods today but you receive your money much later. But when you sell, the company will acknowledge it as revenue….however, the real money will flow in much later. This is not a great thing as it would squeeze the company’s day to day operations.

      To check the debt level, just look at the long term and short term borrowings.

  13. sammandar khan says:

    In the earlier ROE chapter you said high ROE ( after 22% ) is not good but here in the stock screener. com you said. The ROE must be 25% along 20% PAT
    Please clear it

    • Karthik Rangappa says:

      Can you please help me identify the chapter in which I;ve said high ROE is not good? It must be a mistake.

      A high ROE is very desirable, especially if the business is not leveraged.

      • sammandar khan says:

        In Chapter 9th key takeaways 8no.

        If you mean both of high ROE & DEBTS are not good then what should be the ratio of these?
        Thanks a lot

        • Karthik Rangappa says:

          If the debt is high, then ROE tends to increase. So if a company has high ROE, make sure its debt is low. Maybe you can look at debt to equity ratio….something like 0.5 or lower is desirable.

  14. Dhinakaran says:

    Krathik, Thank you once again for the neat explanation.
    1) What is your advice in a > 22+ PE market? Do I need to stick with my positions or do i need to sell part/all of it ? Also what is your take on actively manged Debt funds / Equity portfolio?
    2) I was looking at a company called PAUSHAK limited. Till 2015 earnings were growing at 20% + but after that it became flat and the price dropped. is there any hints that I can use to find if the earnings is going to slow down.
    Thank you!

    • Karthik Rangappa says:

      1) A PE of 22 can be justified in many ways (industry, margins, quality etc). There is no hard and fast rule here. You will have to judge the company from many different angles and not just PE. In fact, personally PE is the last thing I look at.

      2) You will have to investigate – is it a cyclical business? How are the peers doing? Is the industry dependent on a commodity? Threat from cheap replacements from outside?

  15. Akash says:

    Dear Karthik, your material is the best one I have ever seen. It will be helpful for investors like me if you add a module on Mutual Funds also. Apart from that kindly have a separate module on small cap, mid cap and large cap stocks, investment strategies in these stocks etc.

    • Karthik Rangappa says:

      Thanks Akash. I’d love to put up a module on personal finance which will include mutual funds. Will also have a module on financial modelling soon where all these stocks can be discusses.

  16. Sandeep says:

    Hi Karthik,

    You are doing amazing job by helping small retail investors like me to avoid lots and lots of pitfalls that we face in the market. I came to know that you will have a module on financial modelling, it will be of great help to us. Your explanation style makes many complicated topics into simple ones. Once again thanks a lot from the bottom of my heart

    • Karthik Rangappa says:

      Happy to hear these words, Sandeep. Yes, we will have a module on Financial Modelling sometime this year.

  17. mohit_1607 says:

    Hi Karthik,
    First of all, thanks a lot for this excellent firsthand information. Would like to understand, what company reports to refer in case the latest annual reports are not available. Example: If am looking to invest now, I do not have the latest annual reports.

    • Karthik Rangappa says:

      Mohit, the latest AR will be made available within 30 days of filing the annual returns. Check on the company’s website under the investors section.

  18. siddartha says:

    Hi Karthik,

    Thanks for the detailed explanation on each section. It seems simple to understand.Can you please upload articles on how to select the mutual funds based on risk and time lines? It would be of great help to small investors like me 🙂

  19. Santosh Shetti says:

    Hi Karthik,

    What should be our approach while studying Quarterly Reports of the Company?
    Is it exactly same process as studying Annual Report ?
    Please guide.

    Thanks & Regards 🙂

  20. Rushikesh says:

    Really nice explanation, specially practical explanation with examples like PVR, Echer Motors, etc which makes understanding lot easier.
    I only have one question, can u pl tell me how to know what amounts of ratios r to be maintained in each and every category. like debt/equity ratio should be less than 0.5 and gross profit margin should be more than 20%…etc
    I want to know how will I ever know what are the correct ratio amounts I should maintain .

    • Karthik Rangappa says:

      There are no hard and fast rules here, Rushikesh. This is because not two companies are the same – sector, business profile, dynamics etc – everything varies.
