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…

Fearful Investors Losing Faith in Trump?

Mainstream media likes to assign a reason for every squiggle in the stock market, bond market, or commodities.

Today provides an amusing example.

Reuters says Washington’s Mounting Woes Push S&P to Biggest Loss in Three Months.

U.S. stocks sold off on Thursday, with the S&P 500 recording its biggest daily percentage drop in three months as escalating worries about the Trump administration’s ability to push through its economic agenda rattled investors.

Investors appeared to be losing faith in the Trump administration’s ability to move forward with tax cuts and the rest of its domestic economic agenda, some strategists said. Th...

Millennials Are Using Financing To Pay For $450 Blenders

Low wages, mounting student debt and rising rents in the trendy urban centers where millennials prefer to live leave young people with little to spend on luxuries like an iPhone, or tickets to Fyre Festival pt. II. So, since millennials can’t seem to buy anything outright, payment companies are partnering with businesses to offer financing options for goods that, in the past, would’ve gone straight on the credit card, according to MarketWatch.

Volatility on the Rise

Courtesy of Declan.

Today's losses look big on current charts but in a historic context, they weren't too severe. However, big red bars are not to be ignored and 'market leading' Small Caps have felt the full brunt of the selling from July which is bad news for the broader market.  Today's losses in the Russell 2000 undercut the 200-day MA leaving 1,345 as next support (of which I would not be too confident of it holding).


If the Russell 2000 gives up 1,350s then a drop to 1,150s could be on the cards. Things could get ugly if this scenario pl...

As Ukraine's crackdown on corruption continues, three lawmakers from Ukraine’s ruling party revealed this week that they own a combined $45 million in bitcoin, according to a report by RIA Novosti, a Russian foreign news service.

Their holdings came to light during mandatory financial disclosures by members of the Ukrainian parliament, part of an IMF-approved strategy to tamp down corruption in Ukraine. The country's democratic institutions, which were never very robust to begin with, have been further destabilized by...

The App Economy Will Be Worth $6 Trillion in Five Years 

In five years, the app economy will be worth $6.3 trillion, up from $1.3 trillion last year, according to a report released today by app measurement company App Annie. What explains the growth? More people are spending more time and -- crucially -- more money in apps. While on average people aren't downloading many more apps, App Annie expects global app usership to nearly double to 6.3 billion people in the next five years while the time spent in apps will more than double.
