Nobel Prize Winner Paul Krugman Blows His Stack

September 9, 2009

In an amazing article that appeared in the Sunday New York Times, Paul Krugman presents his thoughts on how economists got it so wrong. In short, they believed the Capital Asset Pricing Model and in efficient markets. You’ve got to read the whole article to get the flavor of the amazing fantasy world he describes. He writes:

To be fair, finance theorists didn’t accept the efficient-market hypothesis merely because it was elegant, convenient and lucrative. They also produced a great deal of statistical evidence, which at first seemed strongly supportive. But this evidence was of an oddly limited form. Finance economists rarely asked the seemingly obvious (though not easily answered) question of whether asset prices made sense given real-world fundamentals like earnings. Instead, they asked only whether asset prices made sense given other asset prices. Larry Summers, now the top economic adviser in the Obama administration, once mocked finance professors with a parable about “ketchup economists” who “have shown that two-quart bottles of ketchup invariably sell for exactly twice as much as one-quart bottles of ketchup,” and conclude from this that the ketchup market is perfectly efficient.

Interspersed with some really fascinating background information on warring factions of theoretical economics, Krugman concludes that the possible future of economic theory will veer more toward behavioral economics.

There’s already a fairly well developed example of the kind of economics I have in mind: the school of thought known as behavioral finance. Practitioners of this approach emphasize two things. First, many real-world investors bear little resemblance to the cool calculators of efficient-market theory: they’re all too subject to herd behavior, to bouts of irrational exuberance and unwarranted panic. Second, even those who try to base their decisions on cool calculation often find that they can’t, that problems of trust, credibility and limited collateral force them to run with the herd.

Hmmm. Exuberance, panic, running with the herd? If you think herd-following sounds suspiciously like trend following, you are right. It turns out that perhaps prices are driven by supply and demand, even when (or especially when) investors are subject to exuberance and panic.

Theories turn out to have consequences if you mistake them for reality. Efficient markets turned out to be as real as the tooth fairy. Everything seems to boil down to supply and demand, where periodic imbalances-for whatever reason-create trends. Our Systematic RS family of accounts is simply an adaptive, unemotional way to navigate markets that turn out to be all too human.


Supply and Demand in the Oil Patch

September 9, 2009

When oil prices were high, apparently regulators believed “evil speculators” were behind the price runup. The Commodity Futures Trading Commission (CFTC) has recently started enforcing position limits differently, even to the extent of revoking no-action letters that were granted previously. On September 4, the CFTC released a report detailing positions held by different categories of investors. An article in The Economist concludes that net positions on one side of the market were not enough to drive prices. The real culprits? Supply, demand, and global instability. Markets are more effective than people think. Supply and demand can get out of whack for a while, but it usually doesn’t take very long until market forces bring them back into alignment.


Who Wins, Who Loses, and Why

September 9, 2009

One of our Senior Portfolio Managers, Harold Parker, has a saying: “To the disciplined go the spoils.” Now there is academic research that supports his point.

From the study by Lo, Repin, and Steenbarger, “Specifically, the survey data indicate that subjects whose emotional reactions to monetary gains and losses were more intense on both the positive and negative side exhibited significantly worse trading performance, implying a negative correlation between successful trading behavior and emotional reactivity.”

That’s a pretty good summation of the problem. The more emotional traders were, the worse they did. Panic and euphoria, which lead to pulling out at the bottom and piling in at the top, are not helpful in financial markets. We find that basing our investment approach on an adaptive, systematic process is very helpful in avoiding the emotional ups and downs of the marketplace.


From Russia With Love

September 9, 2009

From Russia Today another attack on the dollar as a reserve currency. The U.S. is mentioned as “an empire that is too lazy to compete.” Despite the propaganda, even if this change takes a long time, you can see that there are many constituencies pushing this agenda. It just highlights the need to think globally.


Fight or Flight Reflex

September 4, 2009

How long will the memory of devastating losses experienced by investors in 2008 stay with them and impact their investment decisions?

NPR has an interesting segment on the topic of why fearful memories are so persistent in the brain. (Click here to listen.) For example, consider the behavior of an Iraq war veteran who suffers from post-traumatic stress disorder. Researchers have observed that a soldier who survived a bomb explosion while driving a Humvee in Iraq can have difficulty driving to the supermarket back in the United States years later. Furthermore, it is often said that those who lived through the Great Depression were permanently changed. Case in point, my grandmother still saves aluminum foil to this day in order to save money. The same phenomenon certainly affects investors.

That’s because fear comes from a part of the brain called the amygdala. The amygdala isn’t logical, Ressler says. It just reacts. ”Before we are even consciously aware of something the amygdala has activated the fight-or-flight reflex,” he says, “and activated the fear system.

So, the question for investors is whether this fight-or-flight reflex will be beneficial to the investor going forward. I would suggest that it could potentially be beneficial if the events that caused the fearful memory were to repeat itself with regularity in the future. However, it is much more likely that this fearful memory will cause more harm than good to the investor. How can an investor cope with this problem? The NPR segment suggests that the answer may some day be to take a pill. Perhaps. However, here and now an investor can rely on a systematic process that has enough flexibility to thrive in a wide variety of market environments. This was the very thinking behind the development of our Global Macro strategy. The systematic process is the key to overcoming the negative affects of fearful memories.

The Importance of Investment Process

September 3, 2009

Vitaliy Katsenelson’s article in Real Clear Markets is a must read.

Spend more time focusing on the process than on the end results. If it was not for randomness, every decision we made would be right or wrong based solely on the outcome. If that were the case, the process could be judged solely on the end result.

But randomness is constantly present in investing (as it is in gambling). Though we are drawn to judge our own decisions, and those of others, on their outcomes, that is dangerous. Randomness may teach us the wrong lessons.

The minority of investors who understand this concept are the ones who make all of the money over the long term.

Children of the Bull Market and the New Normal

September 2, 2009

Bill Gross has an extended discussion of what he calls the “new normal” in his most recent commentary. A couple of things stood out to me. First, he pointed out the tendency of all current investors to think that the way markets have worked in the past is the way they will always work. He writes:

“This “new” vs. “old” normal dichotomy was perhaps best contrasted by Barton Biggs, as I heard him on Bloomberg Radio in early 2009, when he said he was a “child of the bull market.” I thought that was a brilliant phrase, and Barton is a brilliant phrase-maker. He went on to say though, that his point was that for as long as he’s been in the business – and that’s a long time – it has paid to buy the dips, because markets, economies, profits, and assets always rebounded and went to higher levels. That is not only the way that he learned it, but that is the way, basically, that capitalism is supposed to work. Economies grow, profits grow, just like children do. I think that’s why he said he was a child of the bull market, not just because he had experienced it for so long, but also because economic growth and higher asset prices are almost invariably a natural evolution, much like the maturation of a person. That’s how people grow, and so I think Barton was saying that capitalism just grows that way too.

Well, the surprise is that there’s been a significant break in that growth pattern, because of delevering, deglobalization, and reregulation. All of those three in combination, to us at PIMCO, means that if you are a child of the bull market, it’s time to grow up and become a chastened adult; it’s time to recognize that things have changed and that they will continue to change for the next – yes, the next 10 years and maybe even the next 20 years. We are heading into what we call the New Normal, which is a period of time in which economies grow very slowly as opposed to growing like weeds, the way children do; in which profits are relatively static; in which the government plays a significant role in terms of deficits and reregulation and control of the economy; in which the consumer stops shopping until he drops and begins, as they do in Japan (to be a little ghoulish), starts saving to the grave.”

The point here is what if this time it really is different? What new tricks will need to be learned to navigate if certain things in the financial markets have changed materially? (One thing that most assuredly will not be different, for example, is investor behavior.)

Not surprisingly, Mr. Gross has some speculations on what might be different. One never knows if his crystal ball will be any better than anyone else’s, but I’m sure he’s devoted as much time thinking about the changes in the global economy as the next guy. He thinks that “The investment implications of this New Normal evolution cannot easily be modeled econometrically, quantitatively, or statistically. The applicable word in New Normal is, of course, “new.” The successful investor during this transition will be one with common sense and importantly the powers of intuition, observation, and the willingness to accept uncertain outcomes. As of now, PIMCO observes that the highest probabilities favor the following strategic conclusions:

  1. Global policy rates will remain low for extended periods of time.
  2. The extent and duration of quantitative easing, term financing and fiscal stimulation efforts are keys to future investment returns across a multitude of asset categories, both domestically and globally.
  3. Investors should continue to anticipate and, if necessary, shake hands with government policies, utilizing leverage and/or guarantees to their benefit.
  4. Asia and Asian-connected economies (Australia, Brazil) will dominate future global growth.
  5. The dollar is vulnerable on a long-term basis.

The section that is of most interest to me is his belief that future investment returns will come from across a multitude of domestic and global asset classes. He guesses to some degree where those might be, whereas we do not. In our Global Macro product, we have simply tried to include as many asset classes as possible in the investment universe, then allowed our systematic process to rotate to the asset classes that are strongest.

Mind Games

September 2, 2009

The New York Times has a nice article (click here) about the mind games that can cause great athletes to think themselves into slumps.

Even the strongest athletes have minds fragile enough to form cracks through which doubts can seep.

The article also reveals that tennis star Roger Federer, winner of 15 Grand Slam singles titles, is actually not a robot like I suspected…

Doubts in one’s abilities can have catastrophic effects in investing as well. A string of losses can lead investors to abandon successful trading methodologies because they “think” that something is broken. This is the very reason that we allow all of our buy and sell decisions to be determined by a computer. Our computer doesn’t have bad days or get down on itself. It just grinds away following a set of rules that place the odds in our favor over long periods of time.

Rethinking

September 2, 2009

On the topic of asset allocation, there is a lot of rethinking going on these days as evidenced by this article in the WSJ. The article highlights the differing views that exist in the industry. Some think bonds should have much more weight, some think alternatives should have more weight, and others think that it still makes the most sense to gives stocks the biggest weighting for portfolios with long-time horizons.

For us, we choose not to be painted into a corner. History makes it clear that it can be advantageous to favor different asset classes for long stretches of time, which is why our Global Macro product is designed to be as adaptive as it is.

Banking Can Be Profitable

September 1, 2009

Canada has only six big banks. They really are too big to fail. A recent article in the Wall Street Journal points out, “Not only do Canada’s Big Six banks have diversified earnings streams, including wealth management, insurance and trading, but they also have benefited from a stricter regulatory regime than in the U.S. that kept their leverage in check during the structured-credit boom. That stood them in good stead during the 2008 crash. A healthier consumer debt profile compared with the U.S. also has played a role, as has a more conservative housing market where subprime loans are virtually nonexistent.”

Imagine that! Regulators forced them to control their leverage, they didn’t make loans to overleveraged consumers, and they didn’t make mortgage loans to people who couldn’t make the payments. No bubble, no bust. Voila!-profits.

According to the article, Royal Bank of Canada (RBC) is now the 12th largest bank in the world. It’s encouraging to me that nothing heroic had to be done to bail out the Canadian banks-they are all still profitable.

There is probably nothing wrong with the U.S. banking system that a little common sense regulation can’t fix. It also points out that investment opportunities can be found all over the world, if only one looks for them.


“I Kill You Later”

September 1, 2009

How soon we forget! Private wealth managers at large international banks are once again selling stock accumulators to clients. The accumulator is a derivative akin to a giant call option, although apparently buying the contracts on margin has been cut back. The fallout wasn’t pretty last go round, but apparently anything sold at a ”discount” is popular.

I am always amazed how popular gimmicks can become, as opposed to executing a well thought out systematic investment program.


Dollar Under Fire Again

September 1, 2009

It’s not so much that the dollar has been notably weak in the very recent past—it’s more that the dollar is being assailed as the world’s reserve currency. Now it’s not just the central bank of China that is complaining.

The U.S. has benefited massively since World War II with the dollar as the de facto reserve currency. Because the dollar has become the world’s reserve currency, there is always tremendous demand for dollars. Huge demand for dollars has allowed businesses to borrow dollars cheaply—benefitting mainly U.S. businesses. It has made funding for American companies far more readily available than funding for other international companies, which primarily have to rely on their home market.

The strong demand for dollars has allowed the U.S. government to borrow as much as it wants whenever it wants. While it can be argued that this has been too much of a good thing, it has made financing the U.S. deficit much, much easier than it would otherwise have been.

Foreign creditors are now looking at the current administration’s deficit coming at them like a tidal wave and are beginning to get a little nervous about holding so many dollars and so little of any other currency. If the dollar begins to decline in earnest, I suppose there is the risk that U.S. investors may also decide it would be nice to have a slug of Swiss Francs, Euros, and Aussie dollars, or whatever. If you think the budget deficit is a problem now, just imagine what will happen if the dollar becomes unglued.

American investors aren’t used to thinking about currency exchange rates, but this is one of the consequences of globalization that needs to be considered in your asset allocation.
