Driven toward reward without regard for consequence

This is interesting. However, the conclusion that "individuals with antisocial personality disorder may not be unaware of… consequences… but instead that their intense reward-seeking motivation consumes their attention wholly until they have fulfilled their desire for reward" seems overstated, and only a small piece of the psychopath puzzle.

For a different perspective, that of a financial writer, and an even farther-fetched conclusion, read the second article below. The same data can be interpreted to show that a trader taking on excessive risk is "hopped up on dopamine" so they can’t see negative consequences, making them "kind of a psychopath." Take all this with a grain of salt haloperidol. - Ilene 

Driven toward reward without regard for consequence

Courtesy of TIME, by Tiffany O’Callaghan

TIMEAn overactive dopamine reward system in the brain may help explain why psychopaths pursue rewards without regard for consequences, according to new research published this week in the journal Nature Neuroscience. Previous research has found that individuals who suffer from antisocial personality disorder—often referred to as sociopathology or psychopathology, despite debate over whether these are distinct conditions—lack empathy and fear. Yet this new study, from researchers at Vanderbilt University examines what these individuals may have in excess. According to the study, led by Joshua Buckholtz, a graduate student in psychology at Vanderbilt, individuals with antisocial personality disorder traits show signs of dysfunction in dopamine reward systems—suggesting that, in psychopaths, the drive toward reward can overwhelm all else.

Prior to participating in two different experiments, study subjects completed personality tests to identify presence and severity of psychopathic characteristic—including aggression, lack of empathy, and capacity for manipulation, among other things. Drawing on previous research that has established a strong link between substance abuse and psychopathology, in the first experiment researchers gave participants amphetamine, then used functional Magentic Resonance Imaging (fMRI) brain scans to monitor how dopamine release was affected by the stimulant. In a second experiment, study participants were told that they would be paid for performing a simple task, and researchers conducted brain scans while they completed the tasks.

In both experiments, researchers found that participants who had psychopathic characteristics according to the personality test, were more likely than those without those traits to have greater activity in the nucleus accumbens, the area of the brain associated with dopamine reward processing—whether in response to the chemical stimulant, or the suggestion of monetary reward.

The findings suggest that individuals

Look Out Bears! Fed New QE Now Up to $165 Billion

Courtesy of Lee Adler

I have been warning for months that the Fed would need new QE to counter the impact of massive waves of Treasury supply. I thought that that would come later, rather than sooner. Sorry folks, wrong about that. The NY Fed announced another round of new TOMO (Temporary Open Market Operations) today.

In addition to the $75 billion in overnight repos that the Fed issued and has been rolling over since Tuesday, next week the Fed will issue another $90 billion. They’ll come in the form of three $30 billion, 14 day repos to be offered next week.

That brings the new Fed QE to a total of $165 billion. Even in the worst days of the financial crisis, I can’t remember the Fed ballooning its balance sheet by $165 bi...

Is A Price Revaluation Event About To Happen?

Courtesy of Technical Traders

Skilled technical traders must be aware that price is setting up for a breakout or breakdown event with recent Doji, Hammer
and other narrow range price bars.  These types of Japanese Candlestick patterns are warnings that price is coiling into
a tight range and the more we see them in a series, the more likely price is building up some type of explosive price breakout/breakdown move in the near future.  The ES (S&P 500 E-mini futures) chart is a perfect example of these types of price bars on the Daily chart (see below).

Tri-Star Tops, Three River Evening Star patterns, Hammers/Hangmen and Dojis are all very common near extreme price peaks and troughs.  The rea...

India About To Experience Major Strength? Possible Says Joe Friday

Courtesy of Chris Kimble

If one invested in the India ETF (INDA) back in January of 2012, your total 7-year return would be 24%. During the same time frame, the S&P 500 made 124%. The 7-year spread between the two is a large 100%!

Are things about to improve for the INDA ETF and could it be time for the relative weakness to change? Possible!

This chart looks at the INDA/SPX ratio since early 2012. The ratio continues to be in a major downtrend.

The ratio hit a 7-year low a few months ago and this week it kissed those lows again at (1). The ratio near weeks end is attempting to...

Crude Oil Cycle Bottom aligns with Saudi Oil Attack

Courtesy of Read the Ticker

Do the cycles know? Funny how cycle lows attract the need for higher prices, no matter what the news is!

These are the questions before markets on on Monday 16th Aug 2019:

1) A much higher oil price in quick time can not be tolerated by the consumer, as it gives birth to much higher inflation and a tax on the average Joe disposable income. This is recessionary pressure.

2) With (1) above the real issue will be the higher interest rate and US dollar effect on the SP500 near all time highs.

3) A moderately higher oil price is likely to be absorbed and be bullish as it creates income for struggling energy companies and the inflation shock may be muted. 

We shall see.

Despacito - How to Make Money the Old-Fashioned Way - SLOWLY!

Are you ready to retire?  

For most people, the purpose of investing is to build up enough wealth to allow you to retire.  In general, that's usually enough money to reliably generate a year's worth of your average income, each year into your retirement so that that, plus you Social Security, should be enough to pay your bills without having to draw down on your principle.

Unfortunately, as the last decade has shown us, we can't count on bonds to pay us more than 3% and the average return from the stock market over the past 20 years has been erratic - to say the least - with 4 negative years (2000, 2001, 2002 and 2008) and 14 positives, though mostly in the 10% range on the positives.  A string of losses like we had from 2000-02 could easily wipe out a decades worth of gains.

Still, the stock market has been better over the last 10 (7%) an...
