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…

Yellen Kills The Music, Says "Equity Valuations Are Quite High", Sends Dow Red For 2015

Courtesy of ZeroHedge. View original post here.

Submitted by Tyler Durden.

Back in July 2007 Citi's then CEO Chuck Prince, a little over a year before his bank received a gargantuan government bailout said "as long as the music is playing, you've got to get up and dance." Moments ago Janet Yellen just killed the music:

  • YELLEN SAYS EQUITY MARKET VALUATIONS QUITE HIGH

Or, paraphrased, the $4.5 trillion balance sheet the US created, and the $22 trillion in assets purchased by global central banks to keep the dream alive, has lead to "quite high" stock prices.

The good news for Yellen, is that at least Congress can't blame her for leaking this only to Medley Global Advisors.

The better news: for a lo...

Is the Fed losing control of interest rates?

Is the Fed losing control over interest rates? I’ve heard a rumor that the Fed is in control of interest rates.

If this is true, is Janet raising rates and not telling anyone? The table below looks at the performance of the yields on the 10 & 30-year notes and TLT over the past 90-days. As you can see yields are up nearly 20% in 90 days!

If Janet and the Fed aren’t raising rates right now, is it possible that “Billions of Free Thinking People” are causing rates to move higher?

German Greens Propose Radical Greek Debt Solution

NPC Graf Zeppelin over Capitol 1928

In its German language edition, Der Spiegel ran a piece last night (translation is mine) about a proposal from the German Green Party (Die Grünen) to deal with the Greek debt crisis that is radically different from how its own government has so far approached the situation. The Greens are not in the Berlin government, but they are a force in German politics regardless, if only because the country loves so much to portray itself as green.

The Green Party’s euro working group, made up of foreign policy, finance and economic specialists, first of all says that, realistically speaking,...

ADP Employment Report for April Disappoints Expectations

Courtesy of Doug Short.

The economic mover and shaker this week is the Friday employment report from the Bureau of Labor Statistics. This monthly report contains a wealth of data for economists, probably the most publicized in the near term being the month-over-month change in Total Nonfarm Employment (the PAYEMS series in the FRED repository).

Today we have the April estimate of 169K new nonfarm private employment jobs from ADP. That is the lowest number since the 157K in January of last year, 15 months ago. In addition, the previous month's estimate was revised downward from 189K to 175K.

Sector Detector: Bulls hold the line as market coils in anticipation of a bigger move

After posting record highs the previous week, stocks closed last week slightly down overall. But the major indexes held their psychological levels, including Dow at 18,000, S&P 500 at 2100, NASDAQ at 5,000, and Russell 2000 at 1200. Although the bulls continue to find reliable support levels nearby, strong overhead technical resistance and neutral-to-defensive rankings in our SectorCast fundamentals-based quant model continue to suggest that a major upside breakout is not quite imminent, although a selloff doesn’t seem to be in the cards, either. Overall, stocks appear to be coiling ever tighter while awaiting...

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.

Why Bitcoin's male domination will be its downfall

Here's an interesting argument by Felix Salmon, although I think he is taking two correct observations and mistakenly attributing a cause-and-effect relationship to them: Bitcoin is going nowhere because women are not involved.

More likely, in my opinion, women are not involved in bitcoin because bitcoin is going nowhere (and they know it). Or maybe, simply, bitcoin is going nowhere and women are not involved.

2015 - Biotech Fever

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

PSW Members - well, what a year for biotechs!   The Biotech Index (IBB) is up a whopping 40%, beating the S&P hands down!  The healthcare sector has had a number of high flying IPOs, and beat the Tech Sector in total nubmer of IPOs in the past 12 months.  What could go wrong?

Phil has given his Secret Santa Inflation Hedges for 2015, and since I have been trying to keep my head above water between work, PSW, and baseball with my boys...it is time that something is put together for PSW on biotechs in 2015.

"Hello PSW Members –

This is a non-trading topic, but I wanted to post it during trading hours so as many eyes can see it as possible.  Feel free to contact me directly at jennifersurovy@yahoo.com with any questions.

Last fall there was some discussion on the PSW board regarding setting up a YouCaring donation page for a PSW member, Shadowfax. Since then, we have been looking into ways to help get him additional medical services and to pay down his medical debts.  After following those leads, we are ready to move ahead with the YouCaring site. (Link is posted below.)  Any help you can give will be greatly appreciated; not only to help aid in his medical bill debt, but to also show what a great community this group is.
