Common errors in DCF models

C

Found this great article from Michael Mauboussin, Chief Investment Strategist of Legg Mason Capital Management (LMCM). It is a 12 page article on the common errors investors commit in using the DCF (Discounted cash flow) model.

Personally my approach to valuation (which is not original and mainly developed from reading) is to create a DCF model for three scenarios. I extend the current business condition and create an as-is scenario. So the assumption is that the current growth rates, margins, competitive situation etc will continue as is. The second scenario is an optimistic scenario where in I try to calculate the intrinsic value using the most optimisitic assumptions for growth rates, margins, competitive intensity etc. The third scenario is the pessimistic scenario with poor growth rates, high competitive intensity etc.

I try to associate probability against each scenario and try to calculate the expected value.

So expected value is = intrinsic value (as is) * probability for ‘as is’ + instrinsic value (optimistic scenario)* probability for optimisitic scenario + intrinsic value (pesimistic scenario) * probability for pessimistic scenario.

I also cross check the above expected value with ratio based valuations.

The above approach forces me to think harder on all my assumptions. Also when the annual results are declared for any company I have invested in, I go back to my excel spreadsheet and relook at the numbers, assumptions etc and calculate the new intrinsic value again. This gives me an idea on whether I should sell, buy more or hold.

I am not able to post my valuation / analysis spreadsheet on the blog. If any one is interested, please e-mail me on rohitc99@indiatimes.com

portfolio construction – Size of a bet

p

My earlier tendency when adding a stock to my portfolio was to allocate an arbitrary amount of money to it. The actual bet or the size of the position was initially a fixed amount of money and later it became a fixed percentage of the portfolio (around 5 % usually).

However later I read several articles and charlie munger’s thoughts on investing and have modified my approach. After I have identifed a stock and am willing to commit money to it, I try to evaluate how confident I am about the stock. I try to quantify this confidence level in terms of the margin of safety, which is the discount at which the stock is selling from the intrinsic value of the stock. So if the intrinsic value of the stock (as calculated by me) is 100, and if the stock is selling at 60, then the discount is 40%. So higher the discount or margin of safety, higher my confidence.

In addition, I try to calculate the odds on the stock too. I use the following formulae to calculate the odds

Intrinsic value (under most optimisitic assumptions of growth, profit margins etc) – current price / (current price – intrinsic value (under most pessimistic conditions)

So my cut off in terms of odds is 3:1 and I typically look at stocks selling at a discount of 40% to intrinsic value. The above may seem to be very stringent criteria in terms of selecting stocks, especially under current market conditions. But this criteria has served me well, as I am able to build a huge margin of safety in my purchases. Ofcourse I am using the above criteria for my long term holdings.

My bet or size of the position is generally 2% or 5 % and a max of 10% if my level of confidence is very high. However I am not into portfolio balancing. So if my best idea has done well and is now say 20% of my portfolio and I think is still undervalued, I let it run and remain in the portfolio. The only time I would sell would be if the fundamentals of the company deteriorate or the company becomes highly over valued.


Side note : Just read that capital account convertibility may be introduced in india. That could have major implications for all of us as investors as it is possible that we may be allowed to invest out of india. I think currently we can do that with a limit of 25000 usd, but it is with restrictions. Lets see what kind of freedom the capital account convertibility brings in. I am however optimistic and excited about it.

To invest or not to invest ?

I was looking at one of my first few posts

Market now offering 10:1 odds

And

Investing based on odds …Does it work ?

And saw that back in 2004, the market odds were 10:1

So what are current odds?

With a PE ratio of around 19, the current odds are around 1.4:1 . These odds are based on the last 6 years data. Its very easy to calculate the odds. Just export the nifty PE data from the their website here. The odds are basically the number of days the nifty closed at a PE of more than 19 to the total number of days.

Now the above calculation is very simplistic and one can argue, backward looking. So if you believe the earnings will continue to grow rapidly, interest rates would remain at the current level and the ROE of the indian industry would remain at the current level (around 24%) or increase, then maybe the odds are better. But frankly the margin of safety does not exist. In may 2004, the odds were 10:1 and the expected returns much higher. That’s not necessarily the case now.

The above does not mean that there no investment opportunities out there. Its just that there is no low hanging fruit now. Back in 2003 or 2004, just putting money into the index was good enough. Any PE or valuation screen was throwing up a huge number of stocks. But now, I am not finding too many companies. I am currently looking at Micro inks and Asahi glass and would be posting my analysis soon.

update 21st : saw this update on moneycontrol – With the Sensex touching 11K today, analysts told Moneycontrol that the benchmark is fairly priced at current levels and apart from fundamentals, liquidity is trying to find value in Sensex stocks.

see this table in the article for the valuation of the top sensex stocks

what is magical about 11k ? read this speech by warren buffett at wharton (question 3) where he talks of valuation in terms of band. So it may be possible to say that 10-11k is fairly valued with a certain set of assumptions. But giving a precise number is trying to bring a level of mathematical certainty to something (valuation in this case) where it may not be possible to do so

Do read this speech by warren buffett. I learnt a lot from it

Options as a defensive strategy

O


I got the following comment from abhijeet on my previous post. Instead of replying directly to the comment, I thought of putting my thoughts on options in a separate post.

I have been studying options and futures on and off for sometime (read a few books on it). However I am still not an expert or anywhere close to it to commit a meaningful amount of money to a position. However as a start, I have started looking at options as a defensive strategy. Let me explain

For various reasons I do not have a firm opinion on the valuation of IT firms. One can argue that the future is bright (see the latest issue of
business today for no. of IT deals coming up for renewal this and next year), but at the same time there are several known factors which could upset the applecart. In the end there is little margin of safety in the true graham sense.

So if I hold IT stocks and have a fixed time horizon to sell the stocks, then buying put options is good strategy to limit the losses (and still have an upside). However this strategy is not a costless strategy. It may not be a strategy with a positive expected value. But buying puts acts like an insurance. In the end it would prevent something truly bad from happening to my portfolio, but it is not strategy to make money.

I still look at using options as a defensive strategy as I am not comfortable with an approach which could have an unlimited downside.

Covered call writing as mentioned in comment could be strategy to make money, but I have not tried it at all and not sure how much I could make (net of all the commissions, spreads on the options) unless I had a strong opinion on the stock on which I am writing the covered call. The other risk which I see in options is that not only one has to be correct on the stock, but one has to get the timing right (which I am very bad at – have been wrong more than 50 % of the time whenever I have tried timing)

In the final analysis, even if I am not planning to put any significant money in options, I see a definite value in learning about it.

Time is more valuable than money

T

A strange topic to write on and that too after a gap of almost 15 days. Not sure if anyone missed my posts, but I surely missed posting something on my blog.

I was away mainly due to my regular job demands. So during the last few weeks I did not have much opportunity to analyse any new companies or look at any new investment ideas. But I did have a chance to reflect on time as a key constraint.

Although time is a constraint for anything you do in life, I tend to think of time as a constraint or limitation on my much effort I can devote to investing and reading. Having a job, family and all other assorted interest puts a limit on what I can or cannot do in investing.

Thinking in reverse, I more or less know that I cannot do the following due to my time constraints

  • options trading: It’s a specialised field, requires day to day supervision and lots of effort. Other than the fact that I am no way an expert in it, it is too risky for me as I just do not have the time or the stomach for it
  • Deep value investing: This is the quantitative mode of value investing. I understand this form investing fairly well (atleast I think so), but this form of investing require more effort as one has to churn the portfolio more often. Also tempramentally, I am not comfortable with these ‘cigar-butt’ companies which are lousy companies, but may give a decent return. Also to practise this kind of investing, one has to diversify into a decent number of companies and then track them atleast quarterly
  • Day trading: No time and no temprament for it at all. It looks like easy money these days. But long time back I made a promise to myself to invest into opportunities which I understand and avoid the ones I don’t. In the end I may miss some easy money, but avoid the pain too
  • Gold/ Commodity trading: No time, special knowledge or temprament here


So by this reverse exclusion approach leaves me with searching for good companies with sustaniable competitive advantage which I can hold for long term. It may seem to be a very small area to work in, but it is not. For the size of my portfolio, if I can find 1-2 good companies a year, it is good enough.

Going forward (time permitting) I plan to expand my investment activity to special situation and deep value investing. But that is still some time off.

Also those of you who would have invested in reliance as an arbitrage situation, the bet would have paid off. Pre-split reliance was selling around 850 – 900 a share. Post spilt it is around 1140 a share. A 25 % return in 2 months.

Now I would like to boast that I made a killing and had some terrific insight …blah blah !!. That’s not true. I tried doing a sum of parts analysis before the split and read some articles on this arbitrage situation. Eventually I got stuck on two points

  • How to value reliance infocomm. Conservative valuations (v/s bhart telecom) showed back of the envlope value of 275 per share (300 now). In the end I was not sure of how to value it
  • If reliance infocomm could be valued at 275 per share, the value of the core business was at around a PE of 12 on current year earnings. Again I was not a 100 % sure if that was undervalued as the petrochemical business is on an upswing and the earnings were at a peak


In the end, as I was not very confident on my analysis, I did not make a big commitment. I am not regretting it though. I would rather do nothing if I am not sure than do something just because others are doing it (does not pay to have others think for you). However I am trying to reverse engineer the arbitrage and see how I could have analysed it better and ‘forseen’ this opportunity.

In anyone has an insight or did this in dec/jan before the split, please share with me. I would like to learn from you

Thinking independently

T

There is generally no shortage of recommendations, tips, or get rich – schemes which are pedelled to the general public. You will notice that the number of such ‘schemes’ (for want of better word) increase almost proportionately with the rise in the corresponding asset or the market. So if there is bull market in gold, you will find more of such tips for the gold market. If the stock market is up, then you will get such schemes for the stock market.

Just think about it, how many recommendations or tips did you see for gold in 1999 (gold was 3900 at that time) or for the stock market in 2003.

And now gold is being touted as an investment and so are a lot of low grade stocks. Mutual funds who are supposed to be for the small investors are no better. Try to check on the number on new launches in the last one year versus 2003. I don’t blame the industry for more launches now, because the subscription would be low if the fund gets launched during the bear market. What irritates me that these funds play on your greed. Now you can argue that if one is greedy then one deserves to be punished for it (well , I definitely was for all the IT funds I bought in 2000). But is the behaviour of the mutual funds not that of a drug dealer who supplies the drug to an addict (rather than a doctor or counseller who prevents it)

So what is the antidote to all of the above. The starting point of this post was this comment from abhijeet . If you know that there are people trying to part you from your money, either by preying on your greed or fear or through fraud, how does one protect himself? Here is what I think

No. 1 protection is knowledge. Learn how to invest. I have mad
e it a point never to invest money in any opportunity if I don’t know what are the risks in it (rewards will take care of itself). Now, I have lost a number of opportunities by that, but have also avoided severe losses.

In my case, I tend to remember the losses far more (I think my pain for loss is far more than average) than an average person. It is not the loss of money which has hurt (that hurts too) as much as loss of faith on my own skills. In cases where I have made a bad decision, I tend to remember that very long, even if I may not have lost as much.

As a result, I am extremely cautious in making my investment. That is not same as avoiding it though. The difference is that I try to do as much homework as possible on an opportunity. I try not to make a decision immediately if I find a good opportunity. I make my notes and wait for a couple of days. Then when the intial excitement of finding an undervalued stock is gone, I tend to be more rational.

Finally, I never go any one recommendation. I read a lot of broker reports, blogs etc. but never accept any recommendations on face value. So if I find a recommendation, I try to analyse it on my own and reach my own conclusions.

In some areas which are out of my circle of competence or interest, I don’t even bother. They include gold, commodities etc. Does not mean that one cannot make money on them, just that I am not competent to do it.

Finally, my thinking is derieved from this quote from warren buffett

‘Risk is not knowing what you are doing’

ps: by the same logic, please do not base your decision on stocks which I post here.

Portfolio size matters!

P

The above may sound strange. Ofcourse, warren buffett has famously said that large amounts of capital act as an anchor on investment results, but then it is more so for the professional investor and certainly not for individual investors like us.

But I have different viewpoint and it goes like this. For me investing is more of risk than return. Before I look at the likely returns, I tend to look at what I could lose under the worst case scenario. Now the worst case scenario for an individual stock is ofcourse 100%. But it likely that during a market downturn, the portfolio can drop by 25% or more (even for a conservative investor)

It is under these conditions that the portfolio size becomes important. How much is the portfolio as a % of your networth? If it is 20-25 %, I can rationally handle a loss of upto 50%. But if the portfolio is 100% of my networth, I think I would not be rational if the portfolio drops by 50% or more. I could very likely panic and sell at the bottom. Now you may feel that you would not react in that fashion and it is quite likely. But believe me, if you are one of those who started investing seriously in 1998-99 and saw your portfolio go down right upto 2003, you would have wondered when it would end.

Ofcourse looking back at 2003 now, feels like april/ may 2003 (the lowest point of the indian market) was a wonderful time to start investing as the great bull market was ahead of you. But if history was any guide at that time, the market has gone nowhere in the last 10+ years and one had to have the conviction to hold onto and better add to your portfolio at that time (with a negative performance to boot!). It is precisely for this reason that I am conservative in my approach and once I have a few years of experience and have gone through atleast one bear and bull market will I increase my equity portfolio as % of my networth.

So next time when you hear some one brag that he had fanatastic return last year on his portfolio, ask him what % of his networth has he put into equity and has he gone through a bear market with that percentage. If he/she has a high % of networth in the stock market, has had a fanatastic run in the last 2-3 years and is feeling that he/she is the next warren buffett, smile and better, pray for him that he pulls out before the next bear market.

So what if one is levearged and has more than 100% in the market and has seen only the bull market. Unfortunately these are the people who hit the headlines when the market tanks.

My Worst invesment decision till date

M




My decision to sell L&T in 2003 (after holding for 4 years) has been my worst investment decision till date. Although my cost basis was 190 odd (pre-divesture) and I sold at 230 odd (again pre-divesture) and did not lose money on it, I consider it to be one of my worst decisions because of the following reasons

  1. The stock has since then become a 10 bagger (sells at around 2250 without considering the value of cemex)
  2. I sold off because I became exasparated with the management. Between 2001 and 2003, they would constantly pay lip service to divesting the cement division and would then drag their feet on it. What I failed to realise at that time was that the Kumarmangalam birla group would be able to force the management to divest the business eventually.
  3. Did not appreciate the importance of the business cycle. The E&C sector was in doldrums at that time and as a result L&T (E&C) division profits were depressed. The E&C sector turned around big time after 2003 and every E&C company has benefited since then
  4. Did not do the sum of parts analysis – basically that the sum of value of the various L&T divisions was more than the complete entity.

In the end, my regret is not that I missed a 10 bagger. What clearly pricks me is that my analysis was sloppy and I did not evaluate all the factors clearly. I was looking at the company with a rear mirror view (the Margins and the ROE were poor then and I expected it to continue).

However, I have tried to learn something from this disaster. So here goes

  • understand the sector dynamics when investing in a stock.
  • Appreciate the importance of business cycle. Although predicting it is not critical, but a basic understanding is a must.
  • Focus on sum of parts versus looking at a company as a whole, especially if the company has various different businesses.
  • Have patience
  • Try to avoid a rear mirror view.

Have you had such an experience?

Kelly’s betting system and portfolio configuration

K


Michael J. Mauboussin recently published a paper on the legg mason website called ‘size matters’ on the Kelly criterion and importance of money management.

The paper is slightly technical on probability and an extremely good read. The key point of the paper is that investors should use the kelly criteria of defining the optimum bet size based on the edge or information advantage one has over the market. The formulae is very simple, namely

F = edge/odds

Where F is the percentage of portfolio one should bet. Edge being the expected value of the opportunity and odds being gain expected from the opportunity.

So if one has a meaningful variant perception or edge over the market (translating into a positive expected value) and expects to win big, then the above formulae helps in deciding the size of the bet as a percentage of the portfolio.

In simple terms, if one’s expected value (probability of gain*gain+probability of loss*loss) is high and the gain is also high, then one should bet heavily.

Conceptually I find the above approach very compelling. My own approach has been the similar. For example, if I am confident of a stock (after all the necessary analysis), I tend to allocate a higher amount of money. My definition of low, medium and high is around 2 % , 5% and 10 % of portfolio for a single stock.

Ofcourse the above approach is sub-optimal and would not lead to highest returns over a long period of time. It is not that I have a problem with the formulae. My problem is how do I know that my ‘edge’ is really an edge. Ofcourse whenever I have put money into a stock, the unstated assumption is that I have an edge. but then i invested in tech stocks in 2000 thinking i had an edge. Although I have a quantitative approach of going for a high expected value with a 3:1 odd, I cannot be sure.
So to safeguard myself (against my own ignorance, risk aversion or stupidity or whatever you can call it), I tend to adopt a suboptimal approach which gives me lower returns, but lets me have sound sleep (I have sleep test for risk, if I lose sleep on something, then it is too risky)

But irrespective of how one executes the above concept, it is a very sound one and should be followed to manage risk prudently

Value investing and the role of catalyst

V

As a value investor I have always been concerned about a value trap. A Value trap is a company, which remains cheap forever, and you are not able to make any money out of it.

Now a company can be a value trap for a variety of reasons, which can be

1.The company performance keeps deteriorating and as a result the intrinsic value keeps going down
2.The market just ignores the company and the sector because there is nothing exciting happening in that sector and most of the companies are hardly glamorous
3.Management action can result in a value trap too. The management keeps blowing away the excess cash into unprofitable diversification instead of returning it to the shareholders

So how does one avoid a value trap. I think this is a very important consideration of value investors especially if one is investing in ‘graham’ style bargains. A ‘Catalyst’ is something which one should look out for to avoid a value trap.

A catalyst can be any of the following

1.Likely management action such as buyback, bonus etc
2.Likely asset conversion opportunities such as LBO, de-merger, accquisitions (think L&T for an example of de-merger)
3.Likely shift in demand supply in favor of the company due to changes in the business cycle – steel and commodity companies in the last few years come to mind.
4.Regulatory changes – Banking comes to mind
5.Unexpected earnings increase
6.Finally time – However one should have a defined time horizon in which one would expect the investment to work out.

So when I look at value or deep value stock, I tend to look beyond the numbers. Is there a likely catalyst, which would unlock the value, or am I getting into a value trap? and how long will it take for the catalyst to be play out. That would define my expected returns too.

Ofcourse this concept of catalyst is not some original concept of mine. It is referred to frequently by Mario gabelli and Marty whitman.
