Possible Early Warning Sign for Market Crashes

By Brandon Keim at Wired

Complexity researchers who study the behavior of stock markets may have identified a signal that precedes crashes.

They say the telltale sign is a measure of co-movement, or the likelihood of stocks to move in the same direction. When a market is healthy, co-movement is low. But in the months and years before a crash, co-movement seems to grow.

Regardless of whether stock prices go up or down or stay the same, they do so in tandem. People are copying each other, and a small nudge can send everyone in the same direction. The system appears primed for collapse.

“One of the most important things happening now is that economists are trying to understand, what is systemic risk? When is the entire system vulnerable to disaster? Our results show that we have a direct, unambiguous measure of that vulnerability,” said Yaneer Bar-Yam, president of the New England Complex Systems Institute.

Seen through an econophysicist’s eyes, a stock market panic is an avalanche.

Bar-Yam’s findings, released Feb. 13 on arXiv, are part of an emerging research field known as econophysics. It applies to economics insights from the physical world, especially from systems in which networks of interacting units produce radical collective behaviors.

Heated water turning to gas is one such behavior, known technically as a phase transition. Another is snow gathering into an avalanche. Seen through an econophysicist’s eyes, a stock market panic is an avalanche, too.

Why God Did Not Create the Universe

Map of solar system with satellite dish

There is a sound scientific explanation for the making of our world—no gods required

By STEPHEN HAWKING And LEONARD MLODINOW, WSJ

Many improbable occurrences conspired to create Earth’s human-friendly design, and they would indeed be puzzling if ours were the only solar system in the universe. But today we know of hundreds of other solar systems, and few doubt that there exist countless more among the billions of stars in our galaxy. Planets of all sorts exist, and obviously, when the beings on a planet that supports life examine the world around them, they are bound to find that their environment satisfies the conditions they require to exist.

[...]

Many people would like us to use these coincidences as evidence of the work of God. The idea that the universe was designed to accommodate mankind appears in theologies and mythologies dating from thousands of years ago. In Western culture the Old Testament contains the idea of providential design, but the traditional Christian viewpoint was also greatly influenced by Aristotle, who believed "in an intelligent natural world that functions according to some deliberate design."

That is not the answer of modern science. As recent advances in cosmology suggest, the laws of gravity and quantum theory allow universes to appear spontaneously from nothing. Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist. It is not necessary to invoke God to light the blue touch paper and set the universe going.

Our universe seems to be one of many, each with different laws. That multiverse idea is not a notion invented to account for the miracle of fine tuning. It is a consequence predicted by many theories in modern cosmology. If it is true it reduces the strong anthropic principle to the weak one, putting the fine tunings of physical law on the same footing as the environmental factors, for it means that our cosmic habitat—now the entire observable universe—is just one of many.

Laplace’s Hammer: The End of Economics

Laplace’s Hammer: The End of Economics

Courtesy of Tim at The Psy-Fi Blog 

Clever Man, Stupid Idea

Simon-Pierre LaplaceSimon-Pierre Laplace was a Very Clever Man who did many Very Clever Things. Unfortunately, like many clever men, having got hold of a Brilliant Idea he was rather inclined to go off and use it on everything in sight, which led to a number of Very Odd Conclusions. In fact as far as science goes, he may well have been the original man with a hammer; taking aim at every problem as though it was a nail.

As is the way of these things economists got hold of Laplace’s ideas, converted them to their own and started developing delicate and intricate webs of theories and practices. Unfortunately, over the succeeding three hundred years they’ve failed to keep up with advances in physics and biology, rather leaving economists as the only believers in an approach that suggests we have no free will, a position from which they’re having to be dug out and defused, one unexploded theorist at a time.

Newton’s Error

When Isaac Newton published his theory of gravity he knew it contained a serious flaw; his equations didn’t exactly match what was observed. He reckoned, correctly, that the differences between his theory and the observations were down to the gravitational effect on the planets of other planets – so called perturbations, which he didn’t know how to mathematically model. He said:

“But to consider simultaneously all these causes of motion and to define these motions by exact laws admitting of easy calculation exceeds, if I am not mistaken, the force of any human mind.”

And, of course, he was mistaken. The force of Laplace’s mind successfully solved the problem. Having achieved this, though, Laplace went a stage further. Because he could exactly calculate the position of any planet he could compare this with the results of observations from astronomers. What he discovered changed human history.

Observer Bias

It turned out that observers made errors, but they made them in a particular way – their observations fell about the actual position of the planet in a very distinctive pattern. This pattern, of course, was the ultra-familiar Bell curve or normal distribution. Laplace realised that human error was statistically quantifiable and, therefore, could be effectively eliminated from the data. This…

Experts Agree: It Is Not 2008

If someone were to ask us what year it was, we would probably politely answer that it was 2016, curious to find out whether the inquirer was a) very confused, b) had only recently awoken from a coma and was still unsure of his when-abouts, or c) was a time traveler who got temporarily lost.

In the unlikely case that we should find ourselves unable to remember the year with sufficient precision to ensure a reliable answer, we’d probably consult a calendar. We recently found out that a great many people actually seem to be uncertain about what year it is....

Should You Be 100% Long Stocks?

The New York Times is out with an investing column that posits the following: You should be 100% stocks in your portfolio because, given enough time, they should outperform everything else you can possibly own in an investment account.

And here is the data that “proves” it – as long as you’re willing to bet that the future will look precisely like the past:

2016 Theme #3: The Rise Of Independent (Non-State) Crypto-Currencies

Courtesy of Charles Hugh-Smith at Of Two Minds

A number of systemic, structural forces are intersecting in 2016. One is the rise of non-state, non-central-bank-issued crypto-currencies.

We all know money is created and distributed by governments and central banks. The reason is simple: control the money and you control everything.

The invention of the blockchain and crypto-currencies such as Bitcoin have opened the door to non-state, non-central-bank currencies--money that is global and independent of any state or central bank, or indeed, any bank, as crypto-currencies are structurally peer-to-peer, meaning they don't require a bank to function: people can exchange crypto-currencies to pay for goods and services without a bank acting as a clearinghouse for all these transactions.

This doesn't just open t...

Last year, the S&P 500 large caps closed 2015 essentially flat on a total return basis, while the NASDAQ 100 showed a little better performance at +8.3% and the Russell 2000 small caps fell -5.9%. Overall, stocks disappointed even in the face of modest expectations, especially the small caps as market leadership was mostly limited to a handful of large and mega-cap darlings.

Notably, the full year chart for the S&P 500 looks very much like 2011. It got off to a good start, drifted sideways for...

Mapping The Market

An update on oil proxies

Courtesy of Jean-Luc Saillard

Back in December, I wrote a post on my blog where I compared the performances of various ETFs related to the oil industry. I was looking for the best possible proxy to match the moves of oil prices if you didn't want to play with futures. At the time, I concluded that for medium term trades, USO and the leveraged ETFs UCO and SCO were the most promising. Longer term, broader ETFs like OIH and XLE might make better investment if oil prices do recover to more profitable prices since ETF linked to futures like USO, UCO and SCO do suffer from decay. It also seemed that DIG and DUG could be promising if OIH could recover as it should with the price of oil, but that they don't make a good proxy for the price of oil itself.
