Cheap and durable (price matters !)



Starting note: This is a long post and I am going to cover a lot of ground. I have tried to cover a vast topic in a few pages, which is usually the subject of entire books. As a result, I have tried to simplify and generalize in several cases to make a point.

In the previous post, I tried to make the point that it is not enough to say that a company has a moat and then rush to your broker to put in an order. One needs to answer a couple of questions
 -          Does the company really have a sustainable competitive advantage or a durable moat? A high return on capital is a necessary but not a sufficient condition to demonstrate the presence of a moat
-          It is also important to judge the depth and durability of the moat. Deeper the moat and longer it survives, more valuable is the company

Do not focus too much on the math
I received a few emails asking me about the calculations on how I arrived at the PE ratios. As I said in my previous post, the math is not important for the point I am making - longer a company earns above its cost of capital, higher is its intrinsic value.

I would suggest that you use the standard DCF model and apply whatever assumptions you like for growth, ROE, free cash flow etc and just play around with the duration of the moat or the period for which the company can earn above the cost of capital. It should be quite obvious that longer the duration, higher is the value of the company.

For the really curious, I have uploaded my calculations here. Prepare to be underwhelmed!

Market implied duration
The other point i would like to make is by turning around the equation – If the company has a high PE ratio, the market is telling you that it expects the company to earn above its cost of capital for a long time.

For illustration, let’s take the example of Page industries (past numbers from money control, future numbers are my guess).
Future expected ROE = 50% (roughly 53% in 2014)
Future growth rate = 30% (40% growth in 2010-2014)
Terminal PE = 15
Current price = 14000 (approximately)

If I put in these numbers into DCF formulae, I get a Moat period of around 10 years.

So the market expects the company to grow its profit by 30% per annum for the next 10 years and maintain its current return on capital. This means that the company will earn a profit of  2000 crs by 2025.

So do I think that page industries will maintain its moat for 10 years or longer and grow at 30%?

I don’t know !

However if I did own the stock or planned to buy it, my next step would be to analyze the competitive strength of the company and see if the moat would survive 10 years and beyond, because if it didn’t I would be in trouble as a long term investor.

Precision not possible
In the previous example I used a fancy formulae and a long list of assumptions to suggest that the market considers page industries to have a competitive advantage period or moat (CAP for short) of 10 years.

Once you put a number to some of these fuzzy concepts, it appears that you have solved the problem and are ready to execute.

Nothing could be farther from the truth.

Anytime someone tries to give you a precise number on intrinsic value of a company, look for the assumptions behind it. As you may have read, the best tool for fiction is the spreadsheet.

The above calculation should be the starting and not the end point of your thinking. I typically do the above kind of analysis to look at what the market is assuming and put it into three broad buckets

2-5 years : Market assumes a short duration moat
5-8 years : Market assumes a medium duration moat
8+ years : Market assumes a long duration moat (bullet proof franchise)

Let’s look at some way to analyze the moat and bucket it in some cases

Measuring the moat
A substantial part of my post has been picked up from this note by Michael Mauboussin. The first version of this note was published in around 2002 and the revised one in 2013 (download from here)

If you are truly interested in learning how to discover and measure moats, I cannot stress this note enough (some important parts in the note have been highlighted by me) . Read it and then re-read it a couple of times. The only point missing from this note is the application of the concepts – Michael mauboussion does not provide any detailed examples of applying the concepts to a real life example.

Model 1: Porter’s five forces analysis
I am not going to write a detailed explanation of this model – you can find this here. I have used this model to analyze IT companies in the past – see here. A few more posts on the same topic can be found here and here.

Let me try to explain my approach using an example from the past. Lakshmi machine works was an old position for me (I no longer hold it). As part of the analysis, I did the five forces review of the company/ industry which can be downloaded from here

A few key points about the analysis
-          The entry barriers were quite high in the textile machinery industry. Once a company like LMW has established itself and achieved a market share in excess of 50%, it was difficult for a new competitor to achieve scale. A textile mill with only LMW machines finds it easy to maintain and repair these machines (due to accumulated learning) or get this done from LMW which has a large service network. LMW, due to a large install base, is able to provide a high level of service (network effect) at a low cost (due to scale of operations). So we have a case of positive loop here–  Largest company is able to provide a cost effective solution and high levels of service and still earn a good return on capital

-          The other factors such as Supplier power, substitute products etc are not critical to evaluate the industry

-          There is a certain level of buyer concentration, but the machinery segment has far higher concentration and hence the balance of power is still with LMW

-          Finally rivalry is muted as LMW has a level of customer lockin . A satisfied customer will prefer to continue with the same supplier (Who is also cost effective) as it allows it to achieve a higher uptime in operations and lower cost of maintenance (maintenance team needs to maintain only one brand of machines)

The above is also visible in the form of a very high return on capital for LMW – The company  had a negative working capital for 10+ years and earned 100% + on invested capital at the time of this analysis

As I analyzed the company in 2008, I felt strongly that the company had a medium (5-8) or a long duration moat. It was not important to arrive at a precise number then, as the company was selling at close to cash on books and the business was available for free. Surely a business with a medium term moat was worth more than 0 !

Model 2: Sources of added value
The second mental model i frequently use is the sources of added value – production advantages, customer advantages and government (pages 34-41 of the note)

I have uploaded the analysis for CERA sanitary ware (current holding), I had done in 2011. Look at the rows 14-19 for the details.

A few points to note
-          The company enjoys scale advantages from demand, distribution, advertising etc. As the company gets bigger, these cost advantages would increase ensuring that the company will be able to price its product at the same level as its competitors and still earn a good profit

-          The company also enjoys customer side advantages from brand/ trademarks and availability

As you run through this checklist/ template, you will notice that a company could have either production or customer advantages due to various factors. However a company which has both has a powerful combination. If these two sources of value are working together and growing, then we may be able to say that the company has a medium or long duration moat

In case you are curious, I thought that CERA had a small to medium moat in 2011. This has expanded since then and the company most likely has a long duration moat now.

Model 3: High pricing power
Another key indicator of competitive advantage is the presence of pricing power. The following comment from warren buffett encapsulates it

“The single most important decision in evaluating a business is pricing power. If you’ve got the power to raise prices without losing business to a competitor, you’ve got a very good business. And if you have to have a prayer session before raising the price 10 percent, then you’ve got a terrible business.”

How do you evaluate this ? Look for clues in the annual report or management responses to questions in conference calls. Does the management talk of margins being impacted severely due to cost pressures ?

For example – Companies like Page industries or asian paints are generally able to pass through cost increases to customer without losing volumes. When the input costs drop they can either increase their margins or use this excess profit in advertising and promotions and thus strengthen their competitive position. Can steel or cement companies do the same ?

Other miscellaneous models
  1. Is the competitive advantage structural (based on the business) or the management. An advantage based on the management is a weak moat and can change overnight if the same team is not in charge
  2. Industry structure : A duopoly or an industry with limited competition is more likely to have companies with competitive advantage. Look at batteries, two wheelers or sanitaryware for example. One is likely to find companies with medium or long duration moats in such industry structures.
  3. Govt regulation : This can be due to special ‘connections’. If you find a moat due to this factor, be very careful as this can disappear overnight
A brief synthesis
I have laid out various models of evaluating the competitive advantage of a company. Once you go through this exercise, you can arrive at a few broad conclusions
-          No moat: A majority of the companies do not have a moat. As you go through the above models and are hard pressed to find anything positive, it is an indicator that the company has no competitive advantage. Even if the company has been earning a high  return on capital in the recent past, it could be a cyclical or temporary phenomenon. Look at several commodity companies which did well in the 2006-2008 time frame, only to go down after that.
-          Weak moats : If the moat depends on single a production side advantage such as access to key raw material or government regulation, it’s a weak moat (think mining or telecom companies). The company can lose the advantage at the stroke of a pen, law or whims and fancy of our politicians. In addition the pricing power of such companies is very low. I would categorize such a moat as a weak one and not give it a duration of more than 2-3 years.
-          Strong, but not quite : If the moat depends on customer advantages such as brands or distribution network, the moat is much stronger. A company with a new brand which is either no.1 or no.2 has a much stronger moat. I tend to give the moat a medium duration (5-8 years). The reason for being cautious at this stage is that the company clearly has a competitive advantage, but the strength has not been tested over multiple business cycle. In addition, in some case the business environment is subject to change and one cannot be too confident of the durability of the moat. The example of LMW or CERA in the past is a good one for this bucket
-          The bullet proof franchise :These are companies with multiple customer and production (scale related) advantages. These companies are able to command high margins, can raise prices and at the same time have a very competitive cost structures due to economies of scale. These companies have demonstrated high returns of capital over 10+ years and continue to do so. In such cases, one can assume that duration of the moat is 10+ years. These cases are actually quite easy to identify – asian paints, nestle, Unilevers, pidilite, HDFC twins and so on.

Moats are not static
A key point to keep in mind is that moats are not static, but changing constantly. In some cases the moat can disappear overnight if it depends on the government regulation (such as mine licenses), but usually the change is slow and imperceptible and hence easy to miss.

If you can identify the key drivers of a company’s moat, then you can track those driver to evaluate if the management is strengthening or weakening the moat. For example, the moat of an FMCG company is driven by its brands and distribution network. As a result, it is important to track if the management is investing in the brand and deepening/ widening the distribution network.

In the case of LMW, I think the moat has slowly shrunk due to the entry of Reiter ltd. Reiter was the technology partner and equity holder in LMW. The two companies have since parted ways and Reiter is now competing aggressively in the same space.

LMW has repeatedly indicated that they are now facing a higher level of competition in India and consequently there has been a slow drop in operating profit margins. In addition one can see an increase in the working capital usage too. I cannot precisely state that the moat duration has shrunk from 10.7 years to 6.3 years, but there is increasing evidence that the moat is under pressure. As a result, I exited the stock a few years back.

Putting it all together
Let’s assume that you have done a lot of work and figured out that company has moderate moat possibly 5-8 years. At this point, you can plug in the required variables into a DCF model and analyze the market implied duration of the moat (the way we did for Page industries)

If the market thinks that the company has no moat or a minimal moat, than you have a probable buy. If however the market implied moat is 10+ years, then the decision would be to avoid buying the stock, not matter how good the company

The above sounds simple in theory, but is far more difficult in practice – I never promised that I will be giving you a neat, fool proof formulae of making a lot of money by doing minimal work :)

The moat of a long term investor
If the all of the above sounds too fuzzy and cannot be laid out in a neat formulae, you should actually feel very happy about it. Think about it for a moment – if something is fuzzy and requires a combination of a wide experience, insight and some thinking, it is unlikely to be done successfully by a computer or fresh out of college analysts. 

Can a research analyst go and present this fuzzy thinking to his head of research, who wants a precise target price for the next month ?

So any investor who has a long term horizon and is ready to invest the time and effort to do this type of analysis will find very little competition. It is a general rule of business that lower competition leads to higher returns – the same is true for investing too.

If you buys stocks, the way most people buy shoes, TV or fridges – after due research on features, durability (how long the consumer durable will last) and then compare with price, the result will be much better than average

It is all about durability


The easiest way to justify a high PE stock is to say that it has a moat or in other words a sustainable competitive advantage. Once these magic words are uttered, no further analysis or thinking is needed. If there is a moat, it does not matter if the stock sells at a PE of 30 or 70. It is all the same.

On seeing this type of analysis I am reminded of the following the quote from warren buffett
“What the wise do in the beginning, fools do in the end.”
Moat =high PE, but high PE is not always = Moat

A company with a moat may be justified to have a high PE, but a high PE does not mean the mean presence of a moat.

Even if the company supposedly has a moat, it is important to judge the depth and durability of this moat. In addition , the company should also have the opportunity to re-invest future cash flows into the business at high rates of return to create further value.

Lets explore some of these aspects in further detail

More than knee deep

The depth of the moat is simply the excess returns a company can make over its cost of capital. If a company can earn 30% return on capital, we can clearly see that the moat is deep (18% excess return).

This aspect of the moat is the easiest to figure out – Just pick the financials of the company for the last 10 years and check the return on capital of the company. If the average returns are higher than the cost of capital , then we can safely assume that the company had a moat in the past (the future is a different issue).

I personally use 15% return on capital as a threshold. Any company which has earned 15% or higher over an entire business cycle (roughly 3-5 years) is a good candidate for the presence of a moat in the past. Its important not to consider a single year in the analysis as several cyclical companies show a sudden spurt in profitability, before sliding into mediocrity.

The durability factor

The presence of a moat in the past, is only the starting point of analysis. 

The key questions to ask are
-          Is the moat durable -  will the moat survive in the future ?
-          How long will the moat survive ?
-          Will the moat deepen (Return on capital improve), remain same or reduce.

All these factor are very important in the valuation of a business.  Let try to quantify them. I will be using the discounted flow analysis (without doing the math here) and will also be making some simplifying assumptions
  1. EPS = 10 Rs
  2. Return on capital (ROC) = 22%
  3. Growth in profits = 15 %
  4. Company is able to maintain this return on capital and growth for 10 years. After that the ROC drops to 12% and growth to 8% (leading to a terminal PE of around 12)
If you input the above numbers into a DCF model, the fair value comes to around 230 (PE = 23) 
Lets play with these numbers now – Lets assume we underestimated the durability of the moat. The actual life of the moat turns out to be 20 years and not the 10 years when we first analysed the company. If that is the case, the fair value comes to around 430 (PE=43)
I just described the case of several companies such as HDFC bank, Asian paints, Nestle etc. In case of these companies, the markets assumed a certain excess return period, which turned to be too conservative. Anyone who bought the stock at a high looking PE, was actually buying the stock cheap.



The above point has been explained far better by prof. sanjay bakshi in this lecture.
Lets look at a few more happy cases. Lets assume that the company actually ends up earning an ROC of 50% with a growth of 20%. If you plug in these numbers, the fair value  turns out to be around 440 (PE=44). I may have just described what has happened to page industries since 2008.

 So what are the key points?

The market  when valuing a company is making an implicit assumption on the future return on capital, growth and the period for which both these factors will last (after which they regress to the averages). 

An investor makes an above average return only if these numbers turn out to be better than the assumptions built into the stock at the time of purchase.

What happens if the moat turns out to be weak or non existent ?

You have a dud !

Lets assume in our example, that the business tanks after you buy it. It is never able to earn more than 12% return on capital and grows at around 8%.

If the above unhappy situation happens, then the true fair value of the company is around 120 (PE=12). If this turns out to the case, then you will suffer from a 50% loss of capital as the market re-values the company.

Examples ? Look at the case of  bharti airtel. The company was selling at around 470 or PE of 23 in 2007. The company had an ROC of 31% and growth in excess of 15%. The market was assuming an excess return period of 8-10 years at that point of time.

What has happened since then ? The stock price has dropped by around 25% from its peak over the last 8 years – a loss of 2% per annum, which is not exactly a great return.

The reasons are not difficult to see (as always, in hindsight). The telecom market after growing at a breakneck speed till 2007-08 started slowing down. In addition the competitive intensity of the industry increased with almost all other players losing money for most of the time. If these problems were not enough, Bharti went ahead and made an expensive acquisition (Zain) in Africa which suppressed the return on capital further.

In effect all the key drivers of value, turned south from 2007-08 onwards resulting in a loss for the long term investor.

We can derive some key points from the discussion till now
-          A high return on capital in the past is a necessary, but not a sufficient condition to demonstrate the presence of a moat
-          It is also important to judge the depth and longevity or durability of moat. If your estimate is correct and turns out to be higher than that of the market, then you will excess returns. If not, be prepared to lose money or at best make market level returns .
-          As a corollary a buy and hold works only if you get the durability aspect correct. If the moat shrinks and disappears, a buy and hold strategy will not save you  

So how does one figure out the durability of the moat. There is no magical formulae where you can punch in a set of numbers and out will pop the duration. It is a highly subjective exercise and the topic of the next post.
