Stock Picking Philosophy from Charles Munger - Part 9




The following came from a 1994 article by Charles Munger, best known as one of the lead Berkshire Hathaway investors with Warren Buffett.

As a warning, its very long and talks about a lot of topics from role of math and psychology, business management, stock picking, etc but its very informative.

I've picked out a few more juicy paragraphs from it but if you have time, make sure to read it.  I've broken it up into several smaller chunks that I found interesting and will post them out over a few days.

  • Sector Rotation
In the stock market, some railroad that’s beset by better competitors and tough unions may be available at one-third of its book value. In contrast, IBM in its heyday might be selling at 6 times book value. So it’s just like the pari-mutuel system. Any damn fool could plainly see that IBM had better business prospects than the railroad. But once you put the price into the formula, it wasn’t so clear anymore what was going to work best for a buyer choosing between the stocks. So it’s a lot like a pari-mutuel system. And, therefore, it gets very hard to beat.

What style should the investor use as a picker of common stocks in order to try to beat the market—in other words, to get an above average long-term result? A standard technique that appeals to a lot of people is called “sector rotation”. You simply figure out when oils are going to outperform retailers, etc., etc., etc. You just kind of flit around being in the hot sector of the market making better choices than other people. And presumably, over a long period of time, you get ahead.

However, I know of no really rich sector rotator. Maybe some people can do it. I’m not saying they can’t. All I know is that all the people I know who got rich—and I know a lot of them—did not do it that way.


  • Not worrying about yearly tax avoidance
Another very simple effect I very seldom see discussed either by investment managers or anybody else is the effect of taxes. If you’re going to buy something which compounds for 30 years at 15% per annum and you pay one 35% tax at the very end, the way that works out is that after taxes, you keep 13.3% per annum.

In contrast, if you bought the same investment, but had to pay taxes every year of 35% out of the 15% that you earned, then your return would be 15% minus 35% of 15%—or only 9.75% per year compounded. So the difference there is over 3.5%. And what 3.5% does to the numbers over long holding periods like 30 years is truly eye-opening. If you sit back for long, long stretches in great companies, you can get a huge edge from nothing but the way that income taxes work.

Even with a 10% per annum investment, paying a 35% tax at the end gives you 8.3% after taxes as an annual compounded result after 30 years. In contrast, if you pay the 35% each year instead of at the end,  your annual result goes down to 6.5%. So you add nearly 2% of after-tax return per annum if you only achieve an average return by historical standards from common stock investments in companies with tiny dividend payout ratios.

But in terms of business mistakes that I’ve seen over a long lifetime, I would say that trying to minimize taxes too much is one of the great standard causes of really dumb mistakes. I see terrible mistakes from people being overly motivated by tax considerations.

Warren and I personally don’t drill oil wells. We pay our taxes. And we’ve done pretty well, so far. Anytime somebody offers you a tax shelter from here on in life, my advice would be don’t buy it.
In fact, any time anybody offers you anything with a big commission and a 200-page prospectus, don’t buy it. Occasionally, you’ll be wrong if you adopt “Munger’s Rule”. However, over a lifetime, you’ll be a long way ahead—and you will miss a lot of unhappy experiences that might otherwise reduce your love for your fellow man.

There are huge advantages for an individual to get into a position where you make a few great investments and just sit back and wait: You’re paying less to brokers. You’re listening to less nonsense. And if it works, the governmental tax system gives you an extra 1, 2 or 3 percentage points per annum compounded.

And you think that most of you are going to get that much advantage by hiring investment counselors and paying them 1% to run around, incurring a lot of taxes on your behalf’? Lots of luck.

  • Focusing on your competitive edge
Again, that is a very, very powerful idea. Every person is going to have a circle of competence. And it’s going to be very hard to advance that circle. If I had to make my living as a musician…. I can’t even think of a level low enough to describe where I would be sorted out to if music were the measuring standard of the civilization.

So you have to figure out what your own aptitudes are. If you play games where other people have the aptitudes and you don’t, you’re going to lose. And that’s as close to certain as any prediction that you can make. You have to figure out where you’ve got an edge. And you’ve got to play within your own circle of competence.

If you want to be the best tennis player in the world, you may start out trying and soon find out that it’s hopeless—that other people blow right by you. However, if you want to become the best plumbing contractor in Bemidji, that is probably doable by two-thirds of you. It takes a will. It takes the intelligence. But after a while, you’d gradually know all about the plumbing business in Bemidji and master the art. That is an attainable objective, given enough discipline. And people who could never win a chess tournament or stand in center court in a respectable tennis tournament can rise quite high in life by slowly  developing a circle of competence—which results partly from what they were born with and partly from what they slowly develop through work.

So some edges can be acquired. And the game of life to some extent for most of us is trying to be something like a good plumbing contractor in Bemidji. Very few of us are chosen to win the world’s chess tournaments. Some of you may find opportunities “surfing” along in the new high-tech fields—the Intels, the Microsofts and so on. The fact that we don’t think we’re very good at it and have pretty well stayed out of it doesn’t mean that it’s irrational for you to do it.

  • Investors vs Investment management
I think the reason why we got into such idiocy in investment management is best illustrated by a story that I tell about the guy who sold fishing tackle. I asked him, “My God, they’re purple and green. Do fish really take these lures?” And he said, “Mister, I don’t sell to fish.”

Investment managers are in the position of that fishing tackle salesman. They’re like the guy who was selling salt to the guy who already had too much salt. And as long as the guy will buy salt, why they’ll sell salt. But that isn’t what ordinarily works for the buyer of investment advice.

If you invested Berkshire Hathaway-style, it would be hard to get paid as an investment manager as well as they’re currently paid—because you’d be holding a block of Wal-Mart and a block of Coca-Cola and a block of something else. You’d just sit there. And the client would be getting rich. And, after a while, the client would think, “Why am I paying this guy half a percent a year on my wonderful passive holdings?”

So what makes sense for the investor is different from what makes sense for the manager. And, as usual in human affairs, what determines the behavior are incentives for the decision maker.

  • Sometimes technology improvements don't benefit the company
The great lesson in microeconomics is to discriminate between when technology is going to help you and when it’s going to kill you. And most people do not get this straight in their heads. But a fellow like Buffett does.

For example, when we were in the textile business, which is a terrible commodity business, we were making low-end textiles—which are a real commodity product. And one day, the people came to Warren and said, “They’ve invented a new loom that we think will do twice as much work as our old ones.”
And Warren said, “Gee, I hope this doesn’t work because if it does, I’m going to close the mill.” And he meant it.

What was he thinking? He was thinking, “It’s a lousy business. We’re earning substandard returns and keeping it open just to be nice to the elderly workers. But we’re not going to put huge amounts of new capital into a lousy business.”

And he knew that the huge productivity increases that would come from a better machine introduced into the production of a commodity product would all go to the benefit of the buyers of the textiles. Nothing was going to stick to our ribs as owners.

That’s such an obvious concept—that there are all kinds of wonderful new inventions that give you nothing as owners except the opportunity to spend a lot more money in a business that’s still going to be lousy. The money still won’t come to you. All of the advantages from great improvements are going to flow through to the customers.

Conversely, if you own the only newspaper in Oshkosh and they were to invent more efficient ways of composing the whole newspaper, then when you got rid of the old technology and got new fancy computers and so forth, all of the savings would come right through to the bottom line.

In all cases, the people who sell the machinery—and, by and large, even the internal bureaucrats urging you to buy the equipment—show you projections with the amount you’ll save at current prices with the new technology. However, they don’t do the second step of theanalysis which is to determine how much is going stay home and how much is just going to flow through to the customer. I’ve never seen a single projection incorporating that second step in my life. And I see them all the time. Rather, they always read: “This capital outlay will save you so much money that it will pay for itself in three years.”

So you keep buying things that will pay for themselves in three years. And after 20 years of doing it, somehow you’ve earned a return of only about 4% per annum. That’s the textile business.

And it isn’t that the machines weren’t better. It’s just that the savings didn’t go to you. The cost reductions came through all right. But the benefit of the cost reductions didn’t go to the guy who bought  the equipment. It’s such a simple idea. It’s so basic.

  • Efficiency of Chain Stores
On the subject of advantages of economies of scale, I find chain stores quite interesting. Just think about it. The concept of a chain store was a fascinating invention. You get this huge purchasing power—which means that you have lower merchandise costs. You get a whole bunch of little laboratories out there in which you can conduct experiments. And you get specialization.

If one little guy is trying to buy across 27 different merchandise categories influenced by traveling salesmen, he’s going to make a lot of poor decisions. But if your buying is done in headquarters for a huge bunch of stores, you can get very bright people that know a lot about refrigerators and so forth to do the buying.


  • Profitability differences due to competition 
Here’s a model that we’ve had trouble with. Maybe you’ll be able to figure it out better. Many markets get down to two or three big competitors—or five or six. And in some of those markets, nobody makes any money to speak of. But in others, everybody does very well.

Over the years, we’ve tried to figure out why the competition in some markets gets sort of rational from the investor’s point of view so that the shareholders do well, and in other markets, there’s destructive competition that destroys shareholder wealth.

If it’s a pure commodity like airline seats, you can understand why no one makes any money. As we sit here, just think of what airlines have given to the world—safe travel, greater experience, time with your loved ones, you name it.

Yet, the net amount of money that’s been made by the shareholders of airlines since Kitty Hawk, is now a negative figure—a substantial negative figure. Competition was so intense that, once it was unleashed by deregulation, it ravaged shareholder wealth in the airline business. Yet, in other fields—like cereals, for example—almost all the big boys make out. If you’re some kind of a medium grade cereal maker, you might make 15% on your capital. And if you’re really good, you might make 40%. But why are cereals so profitable—despite the fact that it looks to me like they’re competing like crazy with promotions, coupons and everything else? I don’t fully understand it.

Obviously, there’s a brand identity factor in cereals that doesn’t exist in airlines. That must be the main factor that accounts for it.

And maybe the cereal makers by and large have learned to be less crazy about fighting for market share—because if you get even one person who’s hell-bent on gaining market share….For example, if I were Kellogg and I decided that I had to have 60% of the market, I think I could take most of the profit out of cereals. I’d ruin Kellogg in the process. But I think I could do it.

In some businesses, the participants behave like a demented Kellogg. In other businesses, they don’t. Unfortunately, I do not have a perfect model for predicting how that’s going to happen.
For example, if you look around at bottler markets, you’ll find many markets where bottlers of Pepsi and Coke both make a lot of money and many others where they destroy most of the profitability of the two franchises. That must get down to the peculiarities of individual adjustment to market capitalism. I think you’d have to know the people involved to fully understand what was happening.

  • Bureaucracy
The great defect of scale, of course, which makes the game interesting—so that the big people don’t always win—is that as you get big, you get the bureaucracy. And with the bureaucracy comes the territoriality—which is again grounded in human nature.

And the incentives are perverse. For example, if you worked for AT&T in my day, it was a great bureaucracy. Who in the hell was really thinking about the shareholder or anything else? And in a bureaucracy, you think the work is done when it goes out of your in-basket into somebody else’s in-basket. But, of course, it isn’t. It’s not done until AT&T delivers what it’s supposed to deliver. So you get big, fat, dumb, unmotivated bureaucracies.

They also tend to become somewhat corrupt. In other words, if I’ve got a department and you’ve got a department and we kind of share power running this thing, there’s sort of an unwritten rule: “If you won’t  bother me, I won’t bother you and we’re both happy.” So you get layers of management and associated costs that nobody needs. Then, while people are justifying all these layers, it takes forever to get anything done. They’re too slow to make decisions and nimbler people run circles around them.

The constant curse of scale is that it leads to big, dumb bureaucracy—which, of course, reaches its highest and worst form in government where the incentives are really awful. That doesn’t mean we don’t need governments—because we do. But it’s a terrible problem to get big bureaucracies to behave.
So people go to stratagems. They create little decentralized units and fancy motivation and training programs. For example, for a big company, General Electric has fought bureaucracy with amazing skill. But that’s because they have a combination of a genius and a fanatic running it. And they put him in young enough so he gets a long run. Of course, that’s Jack Welch.


  • The Dangers of Yes Men
Television was dominated by one network—CBS in its early days. And Paley was a god. But he didn’t like to hear what he didn’t like to hear. And people soon learned that. So they told Paley only what he liked to hear. Therefore, he was soon living in a little cocoon of unreality and everything else was corrupt—although it was a great business.

So the idiocy that crept into the system was carried along by this huge tide. It was a Mad Hatter’s tea party the last ten years under Bill Paley.

And that is not the only example by any means. You can get severe misfunction in the high ranks of business. And of course, if you’re investing, it can make a lot of difference. If you take all the acquisitions that CBS made under Paley, after the acquisition of the network itself, with all his advisors—his investment bankers, management consultants and so forth who were getting paid very handsomely—it was absolutely terrible.

For example, he gave something like 20% of CBS to the Dumont Company for a television set manufacturer which was destined to go broke. I think it lasted all of two or three years or something like that. So very soon after he’d issued all of that stock, Dumont was history. You get a lot of dysfunction in a big fat, powerful place where no one will bring unwelcome reality to the boss.

  • Advantages of Scale:
Just as in an ecosystem, people who narrowly specialize can get terribly good at occupying some little niche. Just as animals flourish in niches, similarly, people who specialize in the business world—and get very good because they specialize—frequently find good economics that they wouldn’t get any other way.

And once we get into microeconomics, we get into the concept of advantages of scale. Now we’re getting closer to investment analysis—because in terms of which businesses succeed and which businesses fail, advantages of scale are ungodly important.

For example, one great advantage of scale taught in all of the business schools of the world is cost reductions along the so-called experience curve. Just doing something complicated in more and more volume enables human beings, who are trying to improve and are motivated by the incentives of capitalism, to do it more and more efficiently

Well, if you were Procter & Gamble, you could afford to use this new method of advertising. You could afford the very expensive cost of network television because you were selling so many cans and bottles. Some little guy couldn’t. And there was no way of buying it in part. Therefore, he couldn’t use it. In effect, if you didn’t have a big volume, you couldn’t use network TV advertising which was the most effective technique.  

So when TV came in, the branded companies that were already big got a huge tail wind. Indeed, they prospered and prospered and prospered until some of them got fat and foolish, which happens with prosperity—at least to some people….

And your advantage of scale can be an informational advantage. If I go to some remote place, I may see Wrigley chewing gum alongside Glotz’s chewing gum. Well, I know that Wrigley is a satisfactory product, whereas I don’t know anything about Glotz’s.

So if one is 40 cents and the other is 30 cents, am I going to take something I don’t know and put it in my mouth—which is a pretty personal place, after all—for a lousy dime?

So, in effect, Wrigley , simply by being so well known, has advantages of scale—what you might call an informational advantage.

Similarly, all these huge dvantages of scale allow greater specialization within the firm. Therefore, each person can be better at what he does.

And these advantages of scale are so great, for example, that when Jack Welch came into General Electric, he just said, “To hell with it. We’re either going to be # 1 or #2 in every field we’re in or we’re going to be out. I don’t care how many people I have to fire and what I have to sell. We’re going to be #1 or #2 or out.”

That was a very tough-minded thing to do, but I think it was a very correct decision if you’re thinking about maximizing shareholder wealth. And I don’t think it’s a bad thing to do for a civilization either, because I think that General Electric is stronger for having Jack Welch there.


  • Disadvantages of Scale
And there are also disadvantages of scale. For example, we—by which I mean Berkshire Hathaway—are the largest shareholder in Capital Cities/ABC. And we had trade publications there that got murdered where our competitors beat us. And the way they beat us was by going to a narrower specialization.
We’d have a travel magazine for business travel. So somebody would create one which was addressed solely at corporate travel departments. Like an ecosystem, you’re getting a narrower and narrower specialization.

Well, they got much more efficient. They could tell more to the guys who ran corporate travel departments. Plus, they didn’t have to waste the ink and paper mailing out stuff that corporate travel departments weren’t interested in reading. It was a more efficient system. And they beat our brains out as we relied on our broader magazine.

That’s what happened to The Saturday Evening Post and all those things. They’re gone. What we have now is Motocross—which is read by a bunch of nuts who like to participate in tournaments where they turn somersaults on their motorcycles. But they care about it. For them, it’s the principal purpose of life. A magazine called Motocross is a total necessity to those people. And its profit margins would make you  salivate.

  • Inefficiency of efficient market hypothesis
The first question is, “What is the nature of the stock market?” And that gets you directly to this efficient market theory that got to be the rage—a total rage—long after I graduated from law school.

And it’s rather interesting because one of the greatest economists of the world is a substantial shareholder in Berkshire Hathaway and has been for a long time. His textbook always taught that the stock market was perfectly efficient and that nobody could beat it. But his own money went into Berkshire and made him wealthy. So, like Pascal in his famous wager, he hedged his bet.

Is the stock market so efficient that people can’t beat it? Well, the efficient market theory is obviously roughly right—meaning that markets are quite efficient and it’s quite hard for anybody to beat the market  by significant margins as a stock picker by just being intelligent and working in a disciplined way.

Indeed, the average result has to be the average result. By definition, everybody can’t beat the market. As I always say, the iron rule of life is that only 20% of the people can be in the top fifth. That’s just the way it is. So the answer is that it’s partly efficient and partly inefficient.

  • Race track betting as a model for stock market
The model I like—to sort of simplify the notion of what goes on in a market for common stocks—is the pari-mutuel system at the racetrack. If you stop to think about it, a pari-mutuel system is a market. Everybody goes there and bets and the odds change based on what’s bet. That’s what happens in the stock market.

Any damn fool can see that a horse carrying a light weight with a wonderful win rate and a good post position etc., etc. is way more likely to win than a horse with a terrible record and extra weight and so on and so on. But if you look at the odds, the bad horse pays 100 to 1, whereas the good horse pays 3 to 2. Then it’s not clear which is statistically the best bet using the mathematics of Fermat and Pascal. The prices have changed in such a way that it’s very hard to beat the system.

And then the track is taking 17% off the top. So not only do you have to outwit all the other betters, but you’ve got to outwit them by such a big margin that on average, you can afford to take 17% of your gross bets off the top and give it to the house before the rest of your money can be put to work.
Given those mathematics, is it possible to beat the horses only using one’s intelligence? Intelligence should give some edge, because lots of people who don’t know anything go out and bet lucky numbers and so forth. Therefore, somebody who really thinks about nothing but horse performance and is shrewd and mathematical could have a very considerable edge, in the absence of the frictional cost caused by the  house take.

Unfortunately, what a shrewd horseplayer’s edge does in most cases is to reduce his average loss over a season of betting from the 17% that he would lose if he got the average result to maybe 10%. However, there are actually a few people who can beat the game after paying the full 17%.

  • Importance of making fewer but larger bets
Here again, look at the pari-mutuel system. I had dinner last night by absolute accident with the president of Santa Anita. He says that there are two or three betters who have a credit arrangement with them, now that they have off-track betting, who are actually beating the house. They’re sending money out net after the full handle—a lot of it to Las Vegas, by the way—to people who are actually winning slightly, net, after paying the full handle. They’re that shrewd about something with as much unpredictability as horse racing.

And the one thing that all those winning betters in the whole history of people who’ve beaten the pari-mutuel system have is quite simple. They bet very seldom.

It’s not given to human beings to have such talent that they can just know everything about everything all the time. But it is given to human beings who work hard at it—who look and sift the world for a mispriced be—that they can occasionally find one.

And the wise ones bet heavily when the world offers them that opportunity. They bet big when they have the odds. And the rest of the time, they don’t. It’s just that simple.
That is a very simple concept. And to me it’s obviously right—based on experience not only from the pari-mutuel system, but everywhere else.

And yet, in investment management, practically nobody operates that way. We operate that way—I’m talking about Buffett and Munger. And we’re not alone in the world. But a huge majority of people have some other crazy construct in their heads. And instead of waiting for a near cinch and loading up, they apparently ascribe to the theory that if they work a little harder or hire more business school students, they’ll come to know everything about everything all the time.

To me, that’s totally insane. The way to win is to work, work, work, work and hope to have a few insights.

How many insights do you need? Well, I’d argue: that you don’t need many in a lifetime. If you look at Berkshire Hathaway and all of its accumulated billions, the top ten insights account for most of it. And that’s with a very brilliant man—Warren’s a lot more able than I am and very disciplined—devoting his lifetime to it. I don’t mean to say that he’s only had ten insights. I’m just saying, that most of the money came from ten insights.

So you can get very remarkable investment results if you think more like a winning parimutuel player. Just think of it as a heavy odds against game full of craziness with an occasional mispriced something or other. And you’re probably not going to be smart enough to find thousands in a lifetime. And when you get a few, you really load up. It’s just that simple.

...



And it makes sense to load up on the very few good insights you have instead of pretending to know everything about everything at all times. You’re much more likely to do well if you start out to do something feasible instead of something that isn’t feasible. Isn’t that perfectly obvious?

How many of you have 56 brilliant ideas in which you have equal confidence? Raise your hands, please. How many of you have two or three insights that you have some confidence in? I rest my case.

Stock Picking Philosophy from Charles Munger - Part 1


The following came from a 1994 article by Charles Munger, best known as one of the lead Berkshire Hathaway investors with Warren Buffett.

As a warning, its very long and talks about a lot of topics from role of math and psychology, business management, stock picking, etc but its very informative.

I've picked out a few more juicy paragraphs from it but if you have time, make sure to read it.  I've broken it up into several smaller chunks that I found interesting and will post them out over a few days.

  • Graham and the father of value investing

The second basic approach is the one that Ben Graham used—much admired by Warren and me. As one factor, Graham had this concept of value to a private owner—what the whole enterprise would sell for if it were available. And that was calculable in many cases.

Then, if you could take the stock price and multiply it by the number of shares and get something that was one third or less of sellout value, he would say that you’ve got a lot of edge going for you. Even with an elderly alcoholic running a stodgy business, this significant excess of real value per share working for you means that all kinds of good things can happen to you. You had a huge margin of safety—as he put it—by having this big excess value going for you.

But he was, by and large, operating when the world was in shell shock from the 1930s—which was the worst contraction in the English-speaking world in about 600 years. Wheat in Liverpool, I believe, got down to something like a 600-year low, adjusted for inflation. People were so shell-shocked for a long time thereafter that Ben Graham could run his Geiger counter over this detritus from the collapse of the 1930s and find things selling below their working capital per share and so on.

...

Of course, the best part of it all was his concept of “Mr. Market”. Instead of thinking the market was efficient, he treated it as a manic-depressive who comes by every day. And some days he says, “I’ll sell you some of my interest for way less than you think it’s worth.” And other days, “Mr. Market” comes by and says, “I’ll buy your interest at a price that’s way higher than you think it’s worth.” And you get the option of deciding whether you want to buy more, sell part of what you already have or do nothing at all.

To Graham, it was a blessing to be in business with a manic-depressive who gave you this series of options all the time. That was a very significant mental construct. And it’s been very useful to Buffett, for instance, over his whole adult lifetime.

However, if we’d stayed with classic Graham the way Ben Graham did it, we would never have had the record we have. And that’s because Graham wasn’t trying to do what we did.

For example, Graham didn’t want to ever talk to management. And his reason was that, like the best sort of professor aiming his teaching at a mass audience, he was trying to invent a system that anybody could use. And he didn’t feel that the man in the street could run around and talk to managements and learn things. He also had a concept that the management would often couch the information very shrewdly to mislead. Therefore, it was very difficult. And that is still true, of course—human nature being what it is.

And so having started out as Grahamites which, by the way, worked fine—we gradually got what I would call better insights. And we realized that some company that was selling at 2 or 3 times book value could still be a hell of a bargain because of momentums implicit in its position, sometimes combined with an unusual managerial skill plainly present in some individual or other, or some system or other.

And once we’d gotten over the hurdle of recognizing that a thing could be a bargain based on quantitative measures that would have horrified Graham, we started thinking about better businesses.

Market Breadth - Weak without Apple

This may sound strange considering how many companies there are in the stock indices, but most of the gains/performance in the stock market over the last couple weeks have been caused by 1 company: Apple.

Source: WSJ


As seen above, Apple makes up 3.8% in the S&P and even more in QQQ, somewhere around 15%.  Below is Apple's performance last few weeks:



That huge spike since mid January is what has been keeping the stock indices from being flat or down.  Its a bit unusual to say the least that one company has such a big impact on the overall market.  

As Bespoke Invest notes: 
While it may seem as if the market has been doing well lately, it really hasn't done anything over the past ten trading days.  Since February 3rd (a Friday), the S&P 500 is flat, and the Dow is actually down about 100 points.  While Apple -- with its huge weighting in the S&P 500 and Nasdaq -- has really helped buoy the market over this time period, underlying breadth has weakened, and the VIX fear index has shot up 25%.  
So will be interesting to see how the market reacts as today's negative reversal in Apple drove the market drop to a significant degree.

Japan Finally Takes Action - Yen Falls

As mentioned previously on this blog, the strong yen has gotten to the point where the Japan Central Bank has to act.  Repeated earning results from Toyota, Honda, Sony, Panasonic, etc all suffer huge losses, partly due to the strong Yen.  Without an intervention in the currency, they will not be able to compete long term.

Yesterday, the Japan central bank finally showed their first hand, announcing a 10 trillion yen asset purchase increase ($128 billion).  As of today, the USD Yen exchange rate has increased from 77.60 to 78.57.

Can this continue?  Unless the JCB increases its asset purchases by another big purchase like this, or two: No.  $128 billion sounds like a lot but as comparison:
In 2011, the Bank of Japan expanded its balance sheet by 11%. But last year, the U.S. Federal Reserve expanded its own by 19%, the Swiss National Bank’s grew by 33% and the European Central Bank expanded its by 36%, Ruskin said.
That “shows just how tough it is for the BOJ to keep up with the Joneses.”
So unless the JCB is willing to commit to their purchase instead of their typical habit of making one move forward before meekly backing down (see multiple occurrences in 2011 such as the post Tsunami intervention), expect the yen to come back strong.  Unfortunately, Japan really can not afford to back down continuously, an increase from 120 to 78 exchange rate over the last 5 yrs has taken a severe toll on its economy and all the poor earning results from its top corporations are showing it.

Daily Reads

Another edition.  Not much going on in the market lately.  S&P is getting close to its 1350 resistance point, so very curious to see what happens soon.


  • China Bailout of Europe?
    • This will be interesting, an "emerging market" bails out a "developed market"?  I can't imagine this will take well to the many many poor people still in China.  However, from a China gov't standpoint, its win win.
  • Asia Real Estate Bull Turn Bear
    • 5 months of straight China real estate declines will do that to you...but the worse is yet to come.

Market Update

In spite of fairly poor earnings and a continuing weak economic outlook, the stock market has been remarkably resilient.  While the market has pulled back for 4 straight sessions until today, it has not dropped appreciably, especially with today's rally.  However, many technical indicators continue to show the same trend of overbought positions.

Some examples below:



  • S&P 500 at almost a year high.



So again, this begs the question of what to do.  While indicators still favor a pull back, the market has been successfully resisting that move.  At this point, one has to decide which is more important: 1) Preventing downside or 2) Missing possible upside.  If preventing downside is more important (after all you can always buy back in at any time) I would recommend a shift to cash/bonds.  If you want to stay exposed for any possible upturns, keep your positions long but watch carefully with stop loss orders and/or hedge with some options.  With this market, volatility comes quick and fast.
