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
An 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.
What's been amazing of late hasn't been the market swings but the extent to which central bankers have contributed to them. Every press conference, statement and newspaper leak of central banks has been pre-empted, interpreted and re-interpreted - all in real time and often within seconds. Investor dependence on the thoughts and actions of central banks isn't new, but it seems to have reached unparalleled and absurd heights.

ANF - Abercrombie & Fitch Co. – Shares in teen retailer, Abercrombie & Fitch Co., are getting hammered today, down 10% at $48.92 in early-afternoon trading after the company reported a wider-than-expected first-quarter loss and missed topline estimates, lowered its full year earnings forecast and said same-store sales would be down slightly for the rest of the year. A review of pre-earnings report activity in Abercrombie options yesterday indicates one trader was prepared for the pullback today. It looks like the strategist initiate...

While the S&P 500 has had quite a year already the Nikkei has been the story of the globe as they are performing acts of central banking that even put the U.S. Fed to shame. And Japan's central bank can buy ETFs and REITs directly per their charter versus the U.S. bank. Combined with a yen in free fall it's been a heck of a move for the Nikkei since last November. I noted last week we were seeing extremely rare weekly and monthly type overbought readings on bo...
The market went through some gyrations on Wednesday in reaction to Fed Chairman Bernanke’s testimony before the Joint Economic Committee. He first defended continued quant easing by warning, “A premature tightening of monetary policy could lead interest rates to rise temporarily but also would carry a substantial risk of slowing or ending the economic recovery.” Stocks dutifully rallied and all major indexes hit new intraday highs.
But alas, consensus is apparently not a given over the longer term. The minutes hinted that a tapering off could start sooner, “A number of participants expressed willingness to adjust the flow of purchases downward as early as the June meeting if the economic information received by that time showed evidence of sufficiently strong and sustained growth.” So …...

I am going to share with you how I manage my IRA and the power of reducing your cost basis. My goal each year is a 20% return in my IRA. Sometimes I make it and sometimes I don't, but I believe that all of my success is due to reducing my cost basis. To illustrate the power of reducing your cost basis here are some trades we did last year. These trades are taken from an educational portfolio we ran in a paper-trading account for a little more than a year.

Well, well, well....it is good to know that there are others in the scientific arena who believed that YMI Bioscience's data (cough - Gilead) is a better drug than Incyte's Jakafi. Now, the definitive data are still unknown, but there was enough evidence from a Phase 2 trial to take a small risk for a huge reward. So, let's forget about Apple (AAPL), and do nothing but biotechs from now until Congress passes universal health care coverage for prescriptions....and drive the prices down so that research and development is no longer feasible to conduct in the US. Even Seattle Genetics (SGEN) has been on a tear as of late...
