Simon-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.
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.
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…

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 backtest reported in a previous article showed that ranking the holdings of USMV, the iShares MSCI USA Minimum Volatility ETF, and selecting a portfolio of the 12 top ranked stocks, provided higher returns for the portfolio than for the underlying ETF. To test these findings out-of-sample we launched the Best12(USMV)-July-2014 model on Jun-30-2014 and published the holdings on our website then. So far this portfolio has gained 8.2%, while USMV is up a mere 2.2%. This test will be expanded by the launch of the second ...
The U.S. economy has had six full years to bounce back since the financial collapse of 2008, and it simply has not happened. Median household income has declined substantially since then, total household wealth for middle class families is way down, the percentage of the population that is employed is still about where it was at the end of the last recession, and the number of Americans that are dependent on the government has absolutely exploded. Even those that claim th...
They call it the New Normal(sic) for a reason: that reason is that as a result of 6+ years of central-planning interventions in the global economy, an experiment that has grown far more monstrous than anything the USSR ever tried to do, everything is now broken: all conventional economic linkages, relationships and correlations you learned about in university are no longer applicable or practical in a world that has taken both Keynesian and monetary theory beyond their wildest extremes.
The result is a ghoulish, macabre collage of mishmash theories applied haphazardly in hopes that something will finally stick, and if not, at least ...
Stocks were able to leverage some optimistic news and dovish words from the Fed to take another stab at an upside breakout attempt last week. Although readers have sometimes accused me of being a permabull, I am really a realist, and the reality is that the slogans like “The trend is your friend” and “Don’t fight the Fed” are truisms. And they have worked. Nevertheless, I am still not convinced that we have seen the ultimate lows for this pullback, especially given the weak technical condition of small caps.
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 ...

Investors are dumping shares in Yahoo, sending the stock down 5.0% to $40.08 after shares in Alibaba made their debut on the floor of the NYSE just before midday. Shares in BABA for their part initially traded up to a high of $99.70, a near 47% increase over the IPO price of $68.00. Typically, one would expect put options that are 5% out of the money with roughly 4-hours left to trade to see waning implied volatility. But, at the start of the trading session and ahead of the first trade for BABA, the Sep 19 ’14 40.0 strike put options were trading with 271% volatility or $0.30 per contract amid uncertainty as to how the start of trading for Alibaba would take shape.
Administradora de Fondos de Pensiones Provida S.A. (PVD) shares will not be trading on the NY Stock Exchange after today. Tomorrow, shares will be harder to sell. Strangely, I wasn't able to find information on the internet, but Paul just sent me a copy of the email he received from Interactive Brokers.
We're selling PVD out of the Virtual Portfolio today at $87.18.

Despite the various opinions on Bitcoin, there is no question as to its ultimate value: its ability to bypass government restrictions, including economic embargoes and capital controls, to transmit quasi-anonymous money to anyone anywhere.
Opinions differ as to what constitutes "money."
The English word "money" derives from the Latin word "moneta," which means to "mint." Historically, "money" was minted in the form of precious metals, most notably gold and silver. Minted metal was considered "money" because it possessed luster, was scarce, and had perceive...

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...
