Thoughts on business risk

T

There are several business models which are seem to be inherently more risky and then there are some businesses which may not be risky to begin with, but changes in industry dynamics can make them risky for some time.

The indian pharma industry seems (atleast to me) to be one such industry. This industry is one of the few industries which is in the process to globalizing. A few years back companies like ranbaxy, Dr reddy’s lab etc got into the mode of releasing generics of blockbuster drugs which were going off patents. I remember distinctly that some of these companies were selling at fairly high PE. The analyst’s could see only a bright future and market was pricing accordingly. To be fair, there were murmurs of litigation risks etc, but somehow that was not visible in the price (with PE of 40 and more).

Later some of these companies had high profile clashes with pharma giants and lost some of the law suits. As a result the stock crashed when the expected payoffs did not materialise. I would look at this strategy of the pharma companies akin to bets in a casino, but where the odds in your favor. What I mean is that the expected payoff is positive in the companies favor, but often some of these bets could fail. So if the market values these companies as if all the bets are going to succeed, then there is a distinct over-valuation. But at the same time, every time a bet fails, if the market prices the company based on the latest failure, then there could be underpricing happening.

The problem (for me only) with the above business model is that I am not able to project the cash flow for such companies as I am not competent to evaluate the odds of success for such bets (investor who can could and should profit from it).

The business risk in the other globalizing star ‘IT services’ seems to be lower as these companies have used mainly labor arbitrage in the initial phases which is a lower risk strategy. However the market recognises that and has bid the stock prices up and so we have a lot of stock related investment risk.

I was have started analysing the textile industry recently. This industry seems to be globalising with the quotas gone. My initial thoughts on the business risk are

  • execution risk for some companies. Not all managements have the capability to manage ‘hyper’ (50%+) growth. Look at arvind mills track record in mid to late 90’s. They invested heavily in denim using debt. The denim cycle turned south and this company was left saddled with huge debt
  • Commodity nature of the product could result in pricing pressure on an ongoing basis
  • Limited leverage with customers – Being a supplier to one of the major retailers will constantly expose these companies to pricing pressure and stiff competiton

Warren Buffett on Benjamin Graham

W

Found the following post on motley fool. I am waiting eagerly for the complete transcript of the Q&A though (emphasis mine)

I recently had the pleasure of taking a large group of students to Omaha for a Q&A with Buffett. When available, I’ll post the results of that Q&A if there is any interest here. In the meantime, I thought I’d mention my most memorable take-away from that meeting.A student noted that Buffett has been a much more successful investor than Graham, and yet Buffett attributes much of his success to Graham, why is that?For the first time, I heard Buffett address this issue head on. Buffett said that it’s true, Graham never got really rich from investing. Ben was much more interested in ideas than in making money. However, the lessons Ben taught are very profitable (in order):1. Stocks represent part ownership in the business. Before Ben, Warren charted prices and did lots of other silly stuff. Ben’s perspective was eye-opening.2. The concept of Mr. Market is vital. The market is very efficient, but not perfectly efficient–and that difference can make you very, very rich. At any point in time, the market price is usually, but not always, appropriate. An intelligent investor is one who can tell the difference between the current market price for a stock and a resonable interpretation of what that part of the business is really worth.3. The margin of safety concept is also vital. Once an intelligent investor discerns the difference between the current market price for a stock and a resonable interpretation of what that part of the business is really worth, it becomes important to build in an appropriate margin of safety.These lessons are Graham’s most important contribution to Buffett and to you and me. Graham’s sensible perspective, combined with Phil Fisher’s (and T. Rowe Price’s) insights on wonderful companies, has made all the difference for Buffett. If we are paying attention, they can make all the difference for us too.

My investing philosophy

M

I think it is extremely important to have well defined investing philosophy to guide one’s decisions and to also to keep your head when there is too much fear or greed in the market.

With the Indian market touching new highs everyday, resisting the urge to get on the bandwagon is fairly important. I have had a loosely defined approach with which I have become comfortable both in terms of the risk and the return and most importantly I am able to sleep soundly in the night.

So here goes my personal investing philosophy (in no specific order)

  1. Invest in companies with sustainable competitive advantage in my own circle of competence with a time horizon of 3-5 years.
  2. Invest in companies where the risk reward ratio is atleast 3:1 in my favor and I have a ‘variant perception’ from the market.
  3. Avoid investing based on any macro-economic point of view or short term opinion (mine or someone else) of the market
  4. Try to beat the market by 5% over a period of 10 years and lowest possible risk (the key word being try)
  5. Avoid loosing money

Thoughts behind each point

  1. I feel comfortable investing in a company whose business is simple to understand and preferably will increase its intrinsic value over a period of time. This enable me to practise a buy and hold philosophy
  2. I prefer 3:1 odds in my favour and a 40-50% discount from conservatively calculated intrinsic value as it enable me to get an average return of 18% per annum
  3. I have avoided investing based on macro-economic point of view or any short term outlook as I am not good at it and consider most of it as noise to be avoided
  4. A return of 5% over the market give translate roughly into 17-18% per annum. Not exactly a return which would get me into investing hall of fame, but over a long period of time it is good for me as it comes with low risk
  5. Point 5 has meant that I have passed a lot of opportunities which looked good, but were not obvious slam dunks. As a result I have been guilty of omission than commision (though I have had my share of duds)

So how has above philosophy worked for me. I would say pretty well, because I think I have been able to achieve more than my targeted returns with very low risk and most importantly, have been able to sleep well.

Please feel free to share your investing philosophy

One way of looking at market valuation ?

O

I have followed a thought process (and here) in terms of looking at market valuation in terms of PE bands. So if the market is below a PE of 12 or below, it likely to be undervalued (odds are favorable for an investor – to the tune of 7:1 or better). At the same time if the PE is more than 20, the market is moving towards overvaluation (unless there is a recession in the economy and earnings are really depressed) and the odds are against an investor (1:3 or worse). However, I found it difficult to form a firm opinion between the above PE levels. The market is typically between these two levels 60-70 % of times and as result I am inactive and not buying an ETF or Index funds. However if the market drops below a PE of 12 or below, I usually start buying actively and if the market goes above a PE of 20, I start a slow liquidation.

I don’t use the above approach to individual stocks, where it is possible for me to have a better idea on whether the stock is over or undervalued (provided the stock is in my circle of competence).

I was pleasently surprised to find the following reply from Warren buffett in his Q&A at Wharton.

I would suggest downloading the Q&A (pdf) and going through the complete transcript for other nuggets of wisdom from buffett.



Q: You made an argument for 7% returns over the next decade in Fortune. Given that (1) profit margins are at least 30% above historical averages, (2) the ratio of prices/GDP is at least 25% above historical averages, and (3) interest rates are ~25% below historical averages, assuming mean reversion, wouldn’t one conclude that while economic earnings growth plus dividends may be 7%, that we are at an unsustainable valuation plateau?


A: We are near the high-end of the valuation band, but not really at an extreme. I have commented on the market 4 or 5 times in Forbes interviews previously (1969, 1974, 1981, and 1977 in Fortune). Most of you can say if something is overvalued or undervalued, you can spot the occasional extreme cases.
There is a big band of valuation and the idea is to calibrate extremes. When I look at a business, I look for people with passion. I can recognize a 98 or a 6, not a 63 (emphasis mine). This rule is good enough in life and investment. You refer to my 2001 article, but returns have not exceeded 7%, so I guess that this is not that precise of a band.


My hurdle rate for active investing

M

I use a hurdle rate which I need to cross if I need to justify the time and effort I spend on investing actively, rather than using a mechanical approach of rupee cost averaging (using an ETF or an index fund)

A rupee cost averaging approach of investing Rs 1000/- per month, every month for the last 10 years would have lead to an average return of around 15% per annum (As an added factor, I added a filter of stopping the plan when the market P/E exceeded 25. I added this filter to ensure that I would avoid putting money in the market when the market seemed overpriced by a decent margin).

This strategy would work even better with a mutual fund with a good long term record of beating the market by a resonable margin (resonable being +3% above market return over a period of 5 years or more).

So in effect if the portfolio of stocks picked by me, does not exceed this hurdle rate of 15% per annum (for a rolling cycle of 5 years and not for every year), then it would not justify the time and the effort.

Luckily till date I have exceeded this rate. But the results are not conclusive, because it could be due to dumb luck. I would consider the results to be conclusive only if I can achieve this kind of outperformance for a period of 10 years or more.

The World According to “Poor Charlie”

T

Found this great interview with charlie munger. Some interesting excerpts from the interview

How much of your success is from investing and how much from managing businesses?
Understanding how to be a good investor makes you a better business manager and vice versa.
Warren’s way of managing businesses does not take a lot of time. I would bet that something like half of our business operations have never had the foot of Warren Buffet in them. It’s not a very burdensome type of business management.
The business management record of Warren is pretty damn good, and I think it’s frequently underestimated. He is a better business executive for spending no time engaged in micromanagement.

Your book takes a very multi-disciplinary approach. Why?
It’s very useful to have a good grasp of all the big ideas in hard and soft science. A, it gives perspective. B, it gives a way for you to organize and file away experience in your head, so to speak.

How important is temperament in investing?
A lot of people with high IQs are terrible investors because they’ve got terrible temperaments. And that is why we say that having a certain kind of temperament is more important than brains. You need to keep raw irrational emotion under control. You need patience and discipline and an ability to take losses and adversity without going crazy. You need an ability to not be driven crazy by extreme success.

How should most individual investors invest?
Our standard prescription for the know-nothing investor with a long-term time horizon is a no-load index fund. I think that works better than relying on your stock broker. The people who are telling you to do something else are all being paid by commissions or fees. The result is that while index fund investing is becoming more and more popular, by and large it’s not the individual investors that are doing it. It’s the institutions.

What about people who want to pick stocks?
You’re back to basic Ben Graham, with a few modifications. You really have to know a lot about business. You have to know a lot about competitive advantage. You have to know a lot about the maintainability of competitive advantage. You have to have a mind that quantifies things in terms of value. And you have to be able to compare those values with other values available in the stock market. So you’re talking about a pretty complex body of knowledge.

What do you think of the efficient market theory, which holds that at any one time all knowledge by everyone about a stock is reflected in the price?
I think it is roughly right that the market is efficient, which makes it very hard to beat merely by being an intelligent investor. But I don’t think it’s totally efficient at all. And the difference between being totally efficient and somewhat efficient leaves an enormous opportunity for people like us to get these unusual records. It’s efficient enough, so it’s hard to have a great investment record. But it’s by no means impossible. Nor is it something that only a very few people can do. The top three or four percent of the investment management world will do fine.

What would a good investor’s portfolio look like? Would it look like the average mutual fund with 2% positions?
Not if they were doing it Munger style. The Berkshire-style investors tend to be less diversified than other people. The academics have done a terrible disservice to intelligent investors by glorifying the idea of diversification. Because I just think the whole concept is literally almost insane. It emphasizes feeling good about not having your investment results depart very much from average investment results. But why would you get on the bandwagon like that if somebody didn’t make you with a whip and a gun?

Should people be investing more abroad, particularly in emerging markets?
Different foreign cultures have very different friendliness to the passive shareholder from abroad. Some would be as reliable as the United States to invest in, and others would be way less reliable. Because it’s hard to quantify which ones are reliable and why, most people don’t think about it at all. That’s crazy. It’s a very important subject. Assuming China grows like crazy, how much of the proceeds of that growth are going to flow through to the passive foreign owners of Chinese stock? That is a very intelligent question that practically nobody asks.

Ibbotson finds 10% average returns back to 1926, and Jeremy Siegel has found roughly the same back to 1802.
Jeremy Siegel’s numbers are total balderdash. When you go back that long ago, you’ve got a different bunch of companies. You’ve got a bunch of railroads. It’s a different world. I think it’s like extrapolating human development by looking at the evolution of life from the worm on up. He’s a nut case. There wasn’t enough common stock investment for the ordinary person in 1880 to put in your eye.

Are you an expert ?

A

Found this new article from ‘Michael J. Mauboussin‘ from Legg Mason capital management ( Links to his other articles can be found on the sidebar and his website).

A highly relevant article for an investor, especially if one is looking at improving his expertise (not necessarily trying to become an expert)
Found the following excerpts very interesting (emphasis mine, comments in italics)

  • What it takes to become an expert appears remarkably consistent across domains. In field after field, researchers find expertise requires many years of deliberate practice. Most people don’t become experts because they don’t put in the time.
  • Experts train their experiential system. Repeated practice allows experts to internalize many facets of their domain, freeing cognitive capacity.
  • Intuition is only reliable in stable environments. In domains that are nonlinear or nonstationary, intuition is much less useful.
  • Expert investors exist. Unfortunately, it is not clear that their skill sets are transferable. Expert investors are likely a product of both mental hard wiring and hard work.

And

Experts are not casual about their domain. They build their lives around deliberate practice and practice every day, including weekends. But experts also report sleep and rest as critical elements of their results, and they avoid overtraining or overexertion. Evidence shows that performance diminution in cognitive tasks coincides more with reductions in deliberate practice than with aging.

As it turns out, expertise requires about ten years, or ten to twenty thousand hours of deliberate practice. Little evidence exists for expert performance before ten years of practice. 3 Even prodigies like Bobby Fischer (chess), Amadeus Mozart (music) and Wayne Gretzky (sports) required a decade of practice to generate world class results – So I have a long way to go. But I enjoy the process of learning, so it is both fun and profitable

Expected value and value to be expected

E

I saw this concept in the book ‘A mathematician plays the stock market’ which I am reading currently and liked the explaination and its relevance to me as an investor.

Expected value is essentially the sum of product of gain/losses from an investment and the associated probabilities. The expected value is the most likely result from an investment.

Let me explain

Let us consider a stock S. I have reasons to believe that the stock would decrease in value by 10%, with a 80% probability. At the same time, there is a long shot product if successful could result in bumper profits and could increase the stock price by 100%. However the chances are just 20% for this event.

So in the above scenario the expected value from the stock is = (-10%)*.8+(+100%)*.2 = 12%
However value most likely result to be expected from such as stock (atleast 80% of the time) is a return of –10%.

A large group of positive ‘expected value’ investment with negative ‘value to be expected’ should be profitable over a period of time. This is same as the principle of arbitrage or value investing from ben graham. The above concept is also critical if one is dealing with options. For example, sellers of put options have a negative expected value (sometimes very high), but a small positive ‘value to be expected’.

So next time if some analyst talks of a positive ‘value to be expected’, you may want to check the assumptions and figure out the ‘expected value’ of the recommendation

The wisdom of Martin Whitman

T

Found the following article on capitalideasonline (bold emphasis and italic comments are mine)

In an investment classic “Greatest Investing Stories”, there is a brilliant piece on Martin Whitman.

“We don’t carry a lot of excess baggage,” he says in the flatted vowels of his native Bronx. “A lot of what Wall Street does has nothing to do with the underlying value of a business. We deal in probabilities, not predictions.”

“The record entitles him to argue that “There are only two kinds of passive investing, value investing and speculative excess.” For the last two years, like 1928-1929 and 1972-1972,” continues Whitman, “we’ve had nothing but speculative excess.”

“These days, argues Whitman, management has to be appraised not only as operators of a going business, “but also as investors engaged in employing and redeploying assets.”

“As a long-term investor looking to a number of possible exit strategies, Whitman glories in the freedom to ignore near-term earnings predictions and results. Acidly, he argues that Wall Street spends far too much time “making predictions about unpredictable things.”

“His search is for companies backed by strong financials that will keep them going through hard times (“safe”), selling at a substantial discount below private business or takeover value (“cheap”). Buying quality assets cheap almost invariably means that the company’s near-term results are rocky enough to have turned off Wall Street. “Markets are too efficient for me to hope that I’d be able to get high-quality resources without the trade-off the near-term outlook not being great,” says Whitman. He chuckles and runs a hand through a fringe of white hair. “When the outlook stinks, you may not have to pay to play.”

“It’s a lot better than being called an indexer or an asset allocator,” he says, taking another poke at standard Wall Street dogma.”

“Whitman’s job is to sniff out what is wrong, and figure out the trade-offs against what is right, particularly in terms of some form of potential asset conversion.”

“Among the most common wrongs Whitman tries to avoid:

a) Attractive-seeming highly liquid cash positions that on inspection prove to be in the custody of managements too timid to put surplus assets to good use;
b) Seductively high rates of return on equity that often signal a relatively small asset base;
c) A combination of low returns on equity and high net asset value that may simply mean that asset values are overstated;
d) High net asset values that may point to a potentially sizable increase in earnings, but which just as often point to swollen over-head.

I have seen point b come up in several of my stock screens. Based purely on the screen, the company looks attractive. Digging deeper show some asset write offs which has artifically raised the return on equity.kind of highlights the risk of relying blindly on stock screen (I never do that though, generally using them to generate a finite list of companies to look at deeper)

“Whitman’s willingness to take on companies like the stereotypical “sick, lame, and lazy” he treated as a pharmacist’s mate – the old salt, in Navy slang, still thinks of himself as having been a “pecker checker” – is not unalloyed. Buying seeming trouble at a discount, Whitman ignores market risk (current price swings). Whitman worries all the time, though, about investment risk (the possibility he may have mis-judged a temporary illness that will prove terminal).”

“As smallish niche producers, often protected by proprietary tech­niques, the equipment manufacturers seemed less vulnerable to shake out, and had better “quality” assets. Unlike the far more capital-intensive chip makers, with their heavy investments in bricks and mortar, the equipment producers operate out of comparatively low-cost clean rooms, and buy, rather than make, most of their components. Research and development costs are high, but Whitman cannily focused on com­panies that expensed rather than capitalized them. Those running charges understated earnings, making them seem particularly weak in the down cycle. So much the worse for Wall Street.”

“Whitman continued to buy a cross section of equipment producers at quotes he regarded as “better than even first stage venture capitalists have to pay, and for companies already public and very, very cash rich.”

“Whitman was averaging down, a key part of his strategy, but anathema to Wall Street’s momentum players.”

Should be done only if one is sure of what he is doing and has strong reasons to believe that the market is wrong ( ‘I feel the stock will do better’ does not quality)

“Most,” he thought, “ought to do okay and a few ought to be huge winners, but there would be a few strikeouts.” The exit strategy for the strikeouts, in a consolidating industry, would almost certainly be acquisition.”

“Beyond diversification, Whitman protected himself by loading up on management that fit his two acid tests: good at day-to-day operations and equally good as asset managers.”

“Once again scoffing at market risk, Whitman underlines the com­forts of being cushioned by strong financials. “When you’re in well­-capitalized companies, if they do start to dissipate, you get a chance to get out.” “On the other hand,” he continues, “when you’re in poorly cap­italized companies, you better watch the quarterly reports very closely.”

“That’s because he thinks in terms of multiple markets. What may seem to be a very rich price to an individual investor can be a perfectly reasonable one for control buyers looking to an acquisition. They can afford to stump up a premium because of the advantages control brings. Among them is the ability to finance a deal on easy terms with what Whitman calls “OPM” (Other People’s Money) and “SOTT” (Something Off The Top) in the form of handsome salaries, options, and other good­ies that come with general access to the corporate treasury.”

Read the book ‘Value Investing : A Balanced Approach’ for a better understanding of multiple market referred to by martin whitman.

“Shop depressed industries for strong financials going cheap and hang on. By strong financials Whitman means companies with little or no debt and plenty of cash. What’s cheap? No hard and fast rules. “Low prices in terms of the resources you get,” he generalizes.”

“Some of his other pricing rules of thumb:

a) For small cap, high-tech companies, a premium of no more than 60 percent over book – about what venture capitalists would pay on a first stage investment.
b) For banks, Whitman’s limit is no more than 80 percent of book value.
c) For money managers, Whitman looks to assets under management (pay no more than two percent to three percent).
d) For real estate companies, he zeros in on discounted appraised values rather than book.”

Good reference point to look at when doing your own valuations for any of these type of companies

“Whitman, thumbing his nose at convention, has clearly established himself as an outside force on Wall Street. Despite the philosophical linkage, he even backs off from identification with what he calls Graham & Dodd Fundamentalists. The basic similarities are striking: long-term horizons, a rigorous analytic approach to the meaning behind reported numbers, and an unshakeable belief that probabilities favor those who buy quality at the lowest possible price. Like Ben Graham, Whitman scoffs at the academicians who hold that stock prices are set by a truly knowledgeable and efficient market. Acknowledging his debt to Graham, Whitman argues that his calculated exploitation of exit strategies has added a new dimension to value investing.”

“Whitman says, “I couldn’t be a trader. I’m very slow with numbers. I have to understand what they mean.”

“It’s the art of the possible,” he says. “The aim is not to maximize profits, but to be consistent at low risk. I never mind leaving something on the table.”

“Whitman, look to a credit against the probability of a default. He looks beyond the credit to see what can be got when it does default-yet another variant on “safe and cheap.”

“Whitman backs this contention with a notably unsentimental view of how Wall Street really works. He argues that heavy reliance on short-­term earnings predictions as the key to market values makes trend play­ers of money managers. Such linkages are the stuff of stock market columns. The Genesco shoe chain allows that fourth quarter earnings will “meet or exceed” analysts’ estimates, and the stock pops with a gain of almost 25 percent. Sykes Enterprises, a call-center specialist, signals that earnings will be down, and the stock falls by a third.”

“Making forecasts about future general market levels,” writes Whitman in Value Investing, “is much more in the realm of abnormal psychology than finance.”

“Analysts who focus on earnings trends to the exclusion of asset val­ues, continues Whitman, tend to think laterally. “The past is prologue; therefore, past growth will continue into the future, or even accelerate.” Unfortunately, the “corporate world is rarely linear,” and becomes a particularly dangerous place for trend players who leave no ‘margin of safety in concentrating on high multiple growth stocks.”

“A bargain that stays a bargain isn’t a bargain.”

I think he is refering to a value trap. A company which stays cheap forever either due to poor management or because the intrinsic value is shrinking

Arithmetic return is what you see, geometric return is what you get

A

I am reading a fairly enjoyable book ‘A Mathematician plays the stock market’ (see section ‘currently reading’ under sidebar). Found the discussion on geometric mean v/s arithmetic mean (for returns) fairly relevant for an investor.

Let me explain

Arithmetic mean (or returns) is the simple average of returns over the time period being considered.

For ex: consider a stock X that has the following returns for the year
Week 1 : + 80 %
Week 2 : -60 %

The average return for a two week period is +10%. The ‘average’ return for the year would be 1.1^52 = 142 times the original investment. If average return is what an investor gets, then anyone can be fabulously rich in no time.

Geometric mean of the same stock will be derieved by the following formulae
Total return = (1+0.8)*(1-0.6)*(1+0.8)…….( for 52 weeks) = 0.000195

The scenario in the above formulae is that the investor makes a positive return the first week, followed by negative the next and then positive and so on. So the real return he/she actually gets is less than 1 % of capital invested

Another example
An investor is on the lookout for a hot mutual fund. He looks at the mutual fund rankings and sees a fund, which has returned 100 % last year. He invests his money in the fund. The hot fund promptly proceeds to lose 50% next year ( reversion to mean or maybe bad luck ).

The return the fund publicizes is 25 % (average for 2 years ). An investor who was invested for 2 years is lucky to get his money back. The performance chasing investor looses half his money. The fund manager and his company get their asset management fee and are able to show great performance at the same time.

Reminds me of a famous title of a book – ‘where are customer’s yatch?’

There is another interesting discussion happening on the BRK board on MSN (registration required ) on the same topic.
