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…

Why Things Aren't What They Used To Be In Emerging Markets

By Franklin Templeton Investments. Originally published at ValueWalk.

The prospect of stabilizing commodity prices and improving corporate earnings has helped rebuild investor interest in emerging markets over the past year. But returning investors may find the constituents of today’s emerging markets are very different from those of the past. I’ve invited my colleague Carlos Hardenberg to share some of his experiences of how emerging markets are not just emerging but evolving, too.

When we look at the emerging-market companies in which we invest today, they are worlds away from the companies we were analysing a decade or two ago.

Trump Issues An Ultimatum To House Republicans: Vote On Friday Or Obamacare Stays

Following a day of narrative twists and turns ahead of what was supposed to be a Thursday night vote to repeal Obamacare, a vote which was pulled in the last moment when over 30 conservative and moderate House republicans threatened to vote against the Ryan/Trump plan, Trump has had enough with the Freedom Caucus dissenters and has issued an informal ultimatum: vote to repeal Obamacare on Friday or Obamacare stays.

If President Trump announces that North Korea launched a missile that landed within 100 miles of Hawaii, would most Americans believe him? Would the rest of the world? We’re not sure, which speaks to the damage that Mr. Trump is doing to his Presidency with his seemingly endless stream of exaggerations, evidence-free accusations, implausible denials and other falsehoods.

Gold Bugs; Stellar performance stage set again

Courtesy of Chris Kimble.

From 2001 to 2011, would you have rather owned the S&P 500 or Gold Miners (Gold Bugs Index/HUI)? If you answered the Gold Bugs index, you would be correct. The left chart below compares the performance of the Gold Bugs Index and the S&P 500. From 2001 to 2011, the Gold Bugs index out performed the S&P 500 by 1,400% (left chart below).

Since 2011, miners have been weaker than the S&P 500 by a large percent. Could the stage be for another period where the mining stocks are going to be stronger than the broad markets again?

Semiconductors Recover at 20-day MA

Courtesy of Declan.

Yesterday's selling didn't follow through with additional losses, instead, indices dug in at lows and managed to recover some of yesterday's selloff.  The best recovery came from the Semiconductor Index. It gained over 1% as it bounced off its 20-day MA. However, it wasn't enough to stop a 'sell' trigger in the MACD and CCI.


Next is the Nasdaq 100. It staged a recovery, but not from a typical support level. Unfortunately, it has a MACD trigger 'sell' from early March and a new 'sell' trigger between the -DI an...

Bitcoin Tumbles Below Gold As China Tightens Regulations

Courtesy of Zero Hedge

Having rebounded rapidly from the ETF-decision disappointment, Bitcoin suffered another major setback overnight as Chinese regulators are circulating new guidelines that, if enacted, would require exchanges to verify the identity of clients and adhere to banking regulations.

A New York startup called Chainalysis estimated that roughly $2 billion of bitcoin moved out of China in 2016.

As The Wall Street Journal reports, the move to regulate bitcoin exchanges brings assurance that Chinese authorities will tolerate some level of trading, after months of uncertainty. A draft of the guidelines also indicates th...

ISPs will soon be able to sell your most private data without your consent.

As expected, Republicans in Congress have begun the process of rolling back the FCC's broadband privacy rules which prevent excessive surveillance. Arizona Republican Jeff Flake introduced a resolution to scrub the rules, using Congress' powers to invalidate recently-approved federal regulations.
