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…

"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.

Futures Levitate As FOMC Begins Two-Day Meeting

Submitted by Tyler Durden.

Overnight markets have been a continuation of the relative peace observed yesterday before the onslaught of key data later in the week, with the biggest mover standing out as the USDJPY, which briefly touched 102 before sliding lower then recouping losses. This sent the Nikkei 225 up 0.57% despite absolutely atrocious Japanese household spending data, coupled with a major deterioration in employment: at this rate if Abenomics doesn't fix the economy it just may destroy it. Aside from that the last 24 hours could be summed as having a lot of noise but not a lot of excitement. This was best illustrated by the S&P500’s (+0.03%) performance which was the second smallest gain YTD. And while the SHCOMP is starti...

Kellogg Call Options Active Ahead Of Earnings

Shares in packaged foods producer Kellogg Co. (Ticker: K) are in positive territory on Monday afternoon, trading up by roughly 0.20% at $65.48 as of 2:20 p.m. ET. Options volume on the stock is well above average levels today, with around 12,500 contracts traded on the name versus an average daily reading of around 1,700 contracts. Most of the volume is concentrated in September expiry calls, perhaps ahead of the company’s second-quarter earnings report set for release ahead of the opening bell on Thursday. Time and sales data suggests traders are snapping up calls at the Sep 67.5, 70.0 and 72.5 strikes. Volume is heaviest in the Sep 72.5 strike calls, with around 4,600 contracts traded against sizable open interest of approximately 11,800 contracts. It looks like traders paid an average premium of $0.37 per contrac...

Sector Detector: Bold bulls dare meek bears to take another crack

Courtesy of Sabrient Systems and Gradient Analytics

Once again, stocks have shown some inkling of weakness. But every other time for almost three years running, the bears have failed to pile on and get a real correction in gear. Will this time be different? Bulls are almost daring them to try it, putting forth their best Dirty Harry impression: “Go ahead, make my day.” Despite weak or neutral charts and moderately bullish (at best) sector rankings, the trend is definitely on the side of the bulls, not to mention the bears’ neurotic skittishness about emerging into the sunlight.

Danger: Falling Prices

Danger: Falling Prices

By Dr. Paul Price of Market Shadows

 

We tried holding up stock prices but couldn’t get the job done. Market Shadows’ Virtual Value Portfolio dipped by 2% during the week but still holds on to a market-beating 8.45% gain YTD. There was no escaping the downdraft after a major Portuguese bank failed. Of all the triggers for a large selloff, I’d guess the Portuguese bank failure was pretty far down most people's list of "things to worry about."

Well PSW Subscribers....I am still here, barely.  From my last post a few months ago to now, nothing has changed much, but there are a few bargins out there that as investors, should be put on the watch list (again) and if so desired....buy a small amount.

First, the media is on a tear against biotechs/pharma, ripping companies for their drug prices.  Gilead's HepC drug, Sovaldi, is priced at $84K for the 12-week treatment.  Pundits were screaming bloody murder that it was a total rip off, but when one investigates the other drugs out there, and the consequences of not taking Sovaldi vs. another drug combinations, then things become clearer.  For instance, Olysio (JNJ) is about $66,000 for a 12-week treatment, but is approved for fewer types of patients AND...
