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.

The Trade Followers Momentum indicator for the S&P 500 Index (SPX) is positive, but showing some short term caution signs. Seven day momentum reached extremely overbought territory last week and has now turned over. Previous peaks of high magnitude have led short term tops in the market by roughly a week or two. The peaks are often associated with sideways or slightly upward action in SPX that ultimately ends with a short term drop in price. This is the first indication of caution; however, it doesn’t imply a large consolidation in price…yet.

This weekend’s must-read is quite apropos of today’s holiday. ‘Profits Without Prosperity’, an incredible article at the Harvard Business Review, shows exactly how corporate share buybacks have gotten out of control in the last decade. It then goes on to point out the various ways in which buybacks-gone-wild are killing the capital formation process in America, holding back the investments needed to keep us competitive and decimating the middle class workforce that actually built this country.

Deja Vu - Someone Tell The Gold-Manipulating-Machines The Market's Shut

Submitted by Tyler Durden.

Just 3 months ago, as Americans celebrated Memorial Day, the spot price of gold jerked $20 higher (then plunged) as gold futures closed. Today, as Americans celebrate Labor Day, the liquidity-less market for spot gold just dropped $6, ripped back and settled lower in the space of a few minutes (with bids and offers fully crossed for a few minutes) as someone clearly forgot to tell the machines that the market is closed...

Makes perfect sense...

Puts Active On Buffalo Wild Wings

Buffalo Wild Wings Inc. (Ticker: BWLD) shares are in positive territory in early-afternoon trading on Thursday, reversing earlier losses to stand up 0.50% on the session at $148.50 as of 12:15 pm ET. Options volume on the restaurant chain is running approximately three times the daily average level due to heavy put activity in the October expiry contracts. It looks like one or more traders are buying the Oct 140/145 put spread at a net premium of roughly $1.45 per contract. As of the time of this writing, the spread has traded approximately 3,000 times against very little open interest at either striking price. The put spread may be a hedge to protect a long stock position against a roughly 6% pullback in the price of the underlying through October expiration, or an outright bearish play anticipating a dip in BWLD shares in the next couple of months. The spread makes money at expiration if shares in BWLD decline 3.3% from the current price of $148.50 to breach the breakeven point...

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...
