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

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

Citigroup Shutters Retail Options Market-Making After Losing War Against HFTs

Anyone following market dynamics in recent months would have been left with the impression that whereas other securities may have had a rather somnolent third quarter, option market makers would be printing cash hand over fist, thanks mostly to the recent boom in retail call option buying, which as shown in the chart below, has seen nearly a doubling in option trading volumes in the past few months and hitting a record 18.4 million in August.

I almost slipped and bought into the SPAC Renaissance. Almost.

Draftkings looks legit. But Draftkings could have been a true IPO. The SPAC wrapper was beside the point. Chamath and Ackman will probably do something legit, those guys usually find a way to win. Maybe a few others. The rest are / will be garbage. My first impression was right.

Nikola’s stock has now fallen from near 100 down into the 20’s as the guy’s whole story has unraveled. Then the guy stepped down and ran away. None of this had to happen. But Nikola arrived on the markets as the quarry of a Special Purpose Acquisit...

FDA's New Standards On Coronavirus Vaccine

WASHINGTON, D.C. (September 23, 2020) -  In an effort to repair its badly damaged reputation, and convince the public that they should take any vaccine it authorizes, the FDA is issuing new standards, but they probably will not convince either experts nor the public that it will be safe and effective, says public interest law professor ...

Is Gold/US Dollar Ratio Sending Bearish Signal To Precious Metals?

Courtesy of Chris Kimble

Last month, I featured this Gold / US Dollar ratio chart in an article warning of the potential for a trend reversal.

While the broader bullish trend is still intact (higher lows since 2015), it could be time for Gold to take a breather.

Looking at today’s “updated” chart, we can see that the ratio formed a “doji star” candle last month with momentum running at peak levels (concerning). And this month we are seeing follow through to the downside (in the form of a red candle).

As well, this bearish reversal pa...

There are a few times in history when a third party said this US paper (stocks, funds or bonds) is worthless.

Here is two.

1) 1965 Nixon Shock - The French said to US we do not want your paper dollars please pay us in gold. This of course led to the US going off the gold standard.

2) 2007 Bear Stern Fund Collapse - Investors said their funds collateral was worth much less than stated. This of course was the beginning of the great america housing bust of 2008.

Adaptive Fibonacci Price Modeling System Suggests Market Peak May Be Near

Courtesy of Technical Traders

Our Adaptive Fibonacci Price Modeling system is suggesting a moderate price peak may be already setting up in the NASDAQ while the Dow Jones, S&P500, and Transportation Index continue to rally beyond the projected Fibonacci Price Expansion Levels.  This indicates that capital may be shifting away from the already lofty Technology sector and into Basic Materials, Financials, Energy, Consumer Staples, Utilities, as well as other sectors.

This type of a structural market shift indicates a move away from speculation and towards Blue Chip returns. It suggests traders and investors are expecting the US consumer to come back strong (or at least hold up the market at...

The numbers of new cases in some of the hardest hit COVID19 states have started to plateau, or even decline, over the past few days. A few pundits have noted it and concluded that it was a hopeful sign. 

Is it real or is something else going on? Like a restriction in the numbers of tests, or simply the inability to test enough, or are some people simply giving up on getting tested? Because as we all know from our dear leader, the less testing, the less...
