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…

Caught On A Hot Mic In 1992, Larry King Assures Bill Clinton: "Ted Turner Would Serve You"

The feud between Donald Trump and CNN hit a new high yesterday when, as previously reported, CNN-owned HLN canceled the show of Dr. Drew Pinsky one week after he said that Hillary’s medical condition was “dangerous” and “concerning." This was troubling, because it again revealed just how biased and partial one of the most popular "news" stations in the US has become.

IMF knew the euro had serious flaws, Sacrificed Greece

By Mauldin Economics. Originally published at ValueWalk.

BY JOHN MAULDIN

There’s a new chapter in the ongoing tale of IMF incompetence. Take a look at this UK Telegraph headline that recently caught my eye.

The love affair was no surprise. Nor was the fact that the IMF had taken part in the immolation of Greece. No, the surprise was that the IMF would publicly disclose the extent of incompetence and massive rule breaking that had taken place.

The Ambrose Evans-Pritchard byline told me this would be a good story. Here’s his lead:

The International Monetary Fund’s top staff misled their own board, made a series of calamitous misjudgments in Greece, became euphoric cheerleade...

S&P 500 Snapshot: A Modest Loss Follows the Jackson Hole Drama

Courtesy of Doug Short's Advisor Perspectives.

This morning's Second Estimate of Q2 GDP at 1.1% was a ho-hum event in advance of Fed Chair Yellen speech at Jackson Hole. And indeed the intraday range volatility of today's session was at the 70th percentile of the 165 market days of 2016 and the widest in 37 sessions. The S&P 500 opened higher, rallied with the opening of her speech, and then sold off sharply during with Vice Chairman Stanley Fischer's suggestion that a couple of rate hikes this year were possible. The index bounced back later in the afternoon to its -0.16% Friday close. The index is down 0.68% for the week.

The yield on the 10-year note closed at at 1.62%, up four basis points from the previous close.

Here is a snapshot of past five sessions in the S&P 500.

Today has certainly been entertaining.

First, Janet Yellen came out with a chart showing there was a 70% chance that rates would be between 0% and 4.5% in 2018.  Is the 90% confidence level -1.0 to 6?

This was followed up by a blast from St. Louis Fed president and FOMC voting member James Bullard that the Fed’s Forecast of Gradual Rate Hikes is Damaging its Credibility and the Economy.

The Federal Reserve’s forecast of gradual rate hikes is damaging the economy and the central bank’s credibility, said St. ...

Epizyme - A Waiting Game

Reminder: Pharmboy is available to chat with Members, comments are found below each post.

Epizyme was founded in 2007, and trying to create drugs to treat patient's cancer by focusing on genetically-linked differences between normal and cancer cells. Cancer areas of focus include leukemia, Non-Hodgkin's lymphoma and breast cancer.  One of the Epizme cofounders, H. Robert Horvitz, won the Nobel Prize in Medicine in 2002 for "discoveries concerning genetic regulation of organ development and programmed cell death."

Before discussing the drug targets of Epizyme, understanding epigenetics is crucial to comprehend the company's goals.  

Genetic components are the DNA sequences that are 'inherited.'  Some of these genes are stronger than others in their expression (e.g., eye color).  Yet, some genes turn on or off due to external factors (environmental), and it is und...
