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…

JPMorgan: Something Has Gone Wrong With the Global Consumer (Bloomberg)

King Dollar and Crude Oil have been have had little correlation over the past year, as each has traded in pretty much opposite directions.

Over the past 9 months King Dollar has had a historical rally and the opposite is true for Crude Oil.

Of late Crude hit its 23% Fibonacci resistance line, based upon last summers weekly closing highs and weekly closing low on 3/13/15.

Joe Friday just the facts….Crude oil is making an attempt to break short-term steep rising support this week and King Dollar is attempting to break short-term steep falling resistance.

Crude oil just experienced its 7th largest 2-month rally in its...

Big Pharma's Business Model is Changing

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

Understanding the new normal of a business model is key to the success of any company.  The managment of companies need to adapt to the changing demand, but first they must recognize what changes are taking place.  Big Pharma's business model is changing rapidly, and much like the airline industry, there will be but a handful of pharma companies left at the end of this path.

Most Big Pharma companies have traditionally done everything from research and development (R&D) through to commercialisation themselves. Research was proprietary, and diseases were cherry picked on the back of academic research that was done using NIH grants.  This was in the heyday of research, where multiple companies had drugs for the same target (Mevocor, Zocor, Crestor, Lipitor), and could reap the rewards on multiple scales.  However, in the c...

By Scott Martindale

Stocks closed last week on a strong note, with the S&P 500 notching a new high, despite lackluster economic data and growth. I have been suggesting in previous articles that stocks appeared to be coiling for a significant move but that the ingredients were not yet in place for either a major breakout or a corrective selloff. However, bulls appear to be losing patience awaiting their next definitive catalyst, and the higher-likelihood upside move may now be underway. Yet despite the bullish technical picture, this week’s fundamentals-based Outlook rankings look even more defensive.

In this weekly update, I give ...

Kimble Charts: US Dollar

Which way from here?

Chris Kimble likes the idea of shorting the US dollar if it bounces higher. Phil's likes the dollar better long here. These views are not inconsistent, actually, the dollar could bounce and drop again. We'll be watching. 

 

Phil writes:  If the Fed begins to tighten OR if Greece defaults OR if China begins to fall apart OR if Japan begins to unwind, then the Dollar could move 10% higher.  Without any of those things happening – you still have the Fed pursuing a relatively stronger currency policy than the rest of the G8.  So, if anything, I think the pressure should be up, not down.  

 

UNLESS that 95 line does ultimately fail (as opposed to this being bullish consolidation at the prior breakout point), then I'd prefer to sell the UUP Jan $25 puts for $0.85 and buy the Sept $24 call...

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.
