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

Fed Queen Race: Personal Income Rises 0.4% as Expected; Good for Rate Hikes? GDP?

Courtesy of Mish.

Personal income for July rose as expected in today's Personal Income and Outlays report. Consumer spending rose nearly as expected, led of course by auto sales. Price pressure was nonexistent.
There's no hurry for a rate hike based on the July personal income and outlays report where inflation readings are very quiet. Core PCE prices rose only 0.1 percent in the month with the year-on-year rate moving backwards, not forwards, to a very quiet plus 1.2 percent. Total prices are also quiet, also at plus 0.1 percent for the monthly rate and at only plus 0.3 percent the yearly rate.

On the consumer, the data are very solid led by a 0.4 percent rise in income that includes a 0.5 percent rise in wages & salaries which is the largest since November last year. Other income ...

Shorts Rally - But For How Long?

Courtesy of Declan.

A second day of gains keeps pressure on shorts in squeezing them out of their positions, but is also looking to sucker shorts into trying to second guess when this rally will end.

The S&P is heading fast towards 2,044. Given the speed at which it has enjoyed this advance it will be there by Tuesday! In reality, it will likely slow before it gets there. When markets do head lower it will be important they do so slowly to sow further doubt into shorts.


The Nasdaq will be testing resistance tomorrow, and is close to coming up against its 200-day MA.  Those who bought the low will be very happy.

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

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.
