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…

Bob Shiller Fears "Substantial Decline" Sees Dow 'Fair Value' Around 11,000

Courtesy of ZeroHedge. View original post here.

Submitted by Tyler Durden.

"This is a dangerous time," warns Nobel laureate Bob Schiller as he warns of the false signal that typical P/E ratios are misleading and in fact his CAPE ratio (looking through the cycle) implies "fair value" for The Dow should trade around 11,000 and around 1300 for the S&P 500. "There is a risk of a substantial decline," he adds, warning that the recent rebound "maybe someone's good will effort to stabilize the market," and in fact the market's valuation is high now and people are over-exposed.

Change investment allocations due to .2% of a move?

Courtesy of Chris Kimble.

Can you believe that its a really big deal to some if an index is down 9.9% from it highs (non correction territory) or if its down 10.1% (correction territory).  Does .2% constitute that we make a different allocation decision? Are you kidding me?

Do you find yourself agreeing more with the person on the left or right? I am in the camp with Lou on the right. Should we make investment decisions based upon a term (correction)? Not me

Interest Rates and Bond Yields: Where are They Headed? September Hike Ideal? Is the Bond Bull Market Over?

Courtesy of Mish.

With all the chatter about whether the Fed will hike on September 17 or not, let's do an interest rate and bond yield recap of where various rates are, where they have been, and where they are likely headed.

Effective Federal Funds Rate



As of yesterday, the effective federal funds rate was a mere 8 basis points. Since April, it has been swinging from a low of 6-8 basis points to a high of 14-15 basis points.

I suspect the odds of a hike are close to 50-50.

The CME Fed Watch has the hike odds at 27% as of September 2. However, the CME does not consider a move to 0.25% a hike....

Gann Angle Apple Inc Review

Courtesy of Read the Ticker.

Time to review Apple Inc with the Gann Angle.

Gann Angles may work best on either daily trading days, daily calendar days, or weekly. All should be considered.

In the chart below Apple Inc works very well. Gann Angles with Fibonacci arc forecasts do work well together.

Any bounce of Apple Inc into previous resistance should be considered as a possible short. Watching and waiting.

Sector Detector: Finally, market capitulation gives bulls a real test of conviction, plus perhaps a buying opportunity

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

The dark veil around China is creating a little too much uncertainty for investors, with the usual fear mongers piling on and sending the vast buy-the-dip crowd running for the sidelines until the smoke clears. Furthermore, Sabrient’s fundamentals-based SectorCast rankings have been flashing near-term defensive signals. The end result is a long overdue capitulation event that has left no market segment unscathed in its mass carnage. The historically long technical consolidation finally came to the point of having to break one way or the other, and it decided to break hard to the downside, actually testing the lows from last ...

Some Hedge Funds "Hedged" During Stock Market Sell Off, Others Not As Risk Focused

By Mark Melin. Originally published at ValueWalk.

With the VIX index jumping 120 percent on a weekly basis, the most in its history, and with the index measuring volatility or "fear" up near 47 percent on the day, one might think professional investors might be concerned. While the sell off did surprise some, certain hedge fund managers have started to dip their toes in the water to buy stocks they have on their accumulation list, while other algorithmic strategies are actually prospering in this volatile but generally consistently trending market.

Bitcoin Battered After "Governance Coup"

Courtesy of ZeroHedge. View original post here.

Naysyers are warning that the recent plunge in Bitcoin prices - from almost $318 at its peak during the Greek crisis, to $221 yesterday - is due to growing power struggle over the future of the cryptocurrency that is dividing its lead developers. On Saturday, a rival version of the current software was released by two bitcoin big guns. As Reuters reports, Bitcoin XT would increase the block size to 8 megabytes enabling more transactions to be processed every second. Those who oppose Bitcoin XT say the bigger block size jeopardizes the vision of a decentralized payments system that bitcoin is built on with some believing ...

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.
