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.
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.
Simon-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.
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.
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…
In recent months, BofA notes that the speed of mean reversion in the VIX has been particularly striking by historical standards. Since the end of QE3, VIX spikes have had very little persistence, generating low cumulative volatility relative to the previous 25 years, underscoring BofA's thesis of a fragile market that features rapid jumps from states of calm to states of stress and back.
As BofA details, markets are hyper-sensitive today to central bank action / rhetoric, with the beta of global equity, commodity, fixed income, FX, and corporate credit mark...

Obamacare’s Maze Turned Millions Into Lawbreakers
Complications arising from the Affordable Care Act (ACA) premium tax credits (PTCs) are causing millions of people to effectively break the law. People who benefit from advance premium tax credits (APTCs) must file tax returns and include a form to reconcile the advanced amount to the actual end-of-year entitled amount. The failure of so many people to fulfill this new legal requirement has led the government to spend more than it should have as APTCs tend to be higher than legally entitled amounts.
Only 8% of people with an APTC received the correct amount in 2014.
This European Bank Solvency issue has been festering in the background for awhile, is this just a little positioning into quarter end, or does it spill into the start of earning`s period next week is this big question for investors. Things could get worse overnight at the European Market open if rumors start spreading.
Federal Reserve Bank of Atlanta President Dennis Lockhart said the central bank is nearing its goals of maximum employment and steady inflation near 2 percent, leaving the economy primed for an increase in borrowing costs.
In early 2009, the seven largest publicly traded college operators were worth a combined $51 billion. Today, they’ve been all but wiped out.
When Barack Obama took office, America’s seven largest publicly traded college operators were worth a combined $51 billion, with more than 815,000 students enrolled at campuses spread across the country. The schools were flooded with with people seeking shelter from the recession, returning to school to pick up new skills.
Almost eight years later, the industry has been decimated. The seven largest listed operators are worth just over $6 billion, and the most valuable co...

I was so pleased yesterday by the announcement that I have joined the Research team at GoldCore as it meant that I could finally start talking about it and was back in a role that lets me indulge in my passion by researching and geeking out on all things gold, silver and money.

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...
