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…

Paul Craig Roberts Rages "Free Financial Markets Are A Hoax"

Courtesy of ZeroHedge. View original post here.

Submitted by Tyler Durden.

Via Paul Craig Roberts,

There are no free financial markets in America, or for that matter anywhere in the Western word, and few, if any, free markets of any other kind. The financial markets are rigged by the big banks, the Federal Reserve, and the Treasury in the interests of the profits of the few big banks and the dollar’s exchange value, which is the basis of US power.

There is a contradiction between a strong currency on one hand and on the other hand massive money creation in order to sustain zero and negative interest rates on the massive debt levels. ...

World War D-Deflation

By John Mauldin, originally published at Thoughts for the Frontline.

Everywhere I go I’m asked, “Will there be inflation or deflation? Are we in a bull or bear market? Is the bond bull market over and will interest rates rise?”

The flippant answer to all those questions is “Yes.” And that can be the correct answer as well, but it depends on what your time frame is and what tools you use to measure the markets and inflation. One of the newer members of the Mauldin Economics team is Jawad Mian, who writes a powerful global macro letter from his base in Dubai. He has been making the case for the “end of the deflation trade” (or more properly the return of a reflationary period) and the knock-on effects that would cause. Longtime readers know that I am in the secular defla...

Dow Jones- 4th tightest trading range in 115 years is about to end!

Courtesy of Chris Kimble.

The tug of war between the bulls and bears has created an unusual situation this year, a historically tight trading range! The chart below reflects that the Dow Jones has traded within a 6.68% high to low trading range this year. That is the 4th tightest trading range through May, in the past 115 years.

The inset table to the right looks at future performance of the Dow following narrow trading ranges through May. As you can see, most of the time the market has ended the year to the upside. Will it be different this time?

STTG Market Recap May 27, 2015

Courtesy of Blain.

Wednesday’s action was almost a 180 degree turn from Tuesday’s with the S&P 500 up 0.92% and the NASDAQ 1.47%.  Sone vague belief in (yet another) resolution in Greece seemed to be the catalyst.   Greek Prime Minister Alexis Tsipras said on Wednesday the negotiations are on the “final stretch” towards a positive deal, Reuters reported.   Later in the day, German Finance Minister Wolfgang Schaeuble said there was not much progress in the Greek debt talks and he was surprised by the upbeat tone from some Greek government officials.  Athens must make a 300 million euro payment to the International Monetary Fund on June 5, ahead of several other payments due to the IMF later in the month, for a total of 1.6 billion euros.

We’ll see if yesterday’s move was the head fake or today’s was shortly.

Sector Detector: Stocks provide a tepid breakout as Fed greases the skids. So now what?

Courtesy of Sabrient Systems and Gradient Analytics

Early last week, stocks broke out, with the S&P 500 setting a new high with blue skies overhead. But then the market basically flat-lined for the rest of the week as bulls just couldn’t gather the fuel and conviction to take prices higher. In fact, the technical picture now has turned a bit defensive, at least for the short term, thus joining what has been a neutral-to-defensive tilt to our fundamentals-based Outlook rankings.

In this weekly update, I give my view of the current market environment, offer a technical analysis of the S&P 500 chart, review our weekly fundamentals-based SectorCast rankings of the ten U.S. business sectors, and then offer up some actionable trading ideas, including a sector rotation strategy using ETFs and an enhanced version using top-ranked stocks from the t...

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...

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.

Help One Of Our Own PSW Members

"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.
