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

Liquidity Strains Reappear As China's "Golden Week" Stock & Housing Market Disappoints

Courtesy of ZeroHedge. View original post here.

Submitted by Tyler Durden.

Despite last night's disappointingly weak China re-open (notably less than US ADRs had implied), it appears everyone and their pet rabbit levered up as China margin-buying rose CNY21bn - the most in 2 months. It appears China's housing market also disappointed hope-strewn expectations as Golden Week home sales slowed dramatically YoY (blamed on weather). All is not well in the liquidioty stress department as despite ongoing injections, o/n HIBOR spiked 240bps overnight. China stocks are mixed at the open as PBOC strengthens the Yuan fix for the 5th day in a row to 2 month highs. Concerns are also growing in China's c...

Chart o' the Day: The (non) Velocity of Money

Courtesy of Joshua M. Brown, The Reformed Broker

Why were the inflation hawks so wrong about quantitative easing? Why didn’t all the “money printing” lead to commodity prices skyrocketing?

One answer is that, while bank reserves were boosted, lending didn’t take off and there was no uptick in the velocity of money – the speed at which capital zooms through the economy and turns over. Absent velocity of money, QE could be looked at as either ineffective or actually causing a deflationary environment, where capital is hoarded and everyone is too petrified to risk it on productive endeavors.

Christopher Wood (CLSA) explains further in his new GREED & fear note:

To GREED & fear the best way to illustrate that quantitative easing is not working is the continuing declin...

S&P 500…Stuck in this zone, welcome to the “Chop House!”

Courtesy of Chris Kimble.


What do S&P 500 bull and bears have in common? There opportunities are being limited by a tight range!

I started sharing with members several weeks ago that the patterns suggested the S&P would be in a “Chop House” environment for a while and that I doubted bulls nor bears would be that happy of campers.

In this type of an environment, unless you are really quick, nimble and accurate, its a time and place to take it easy and let this play out. For the majority of traders, the distance between the close on 8/25 at 186 and the close of 200 on 9/16...

1) The shares of one of my largest short positions (~3%), Exact Sciences, crashed by more than 46% yesterday. Below is the article I published this morning on SeekingAlpha, explaining why I think it’s still a great short and thus shorted more yesterday. Here’s a summary:

  • The U.S. Preventative Services Task Force’s Colorectal Cancer Screening Draft Recommendation issued yesterday is devastating for Exact Sciences’ only product, Cologuard.
  • I think this is the beginning of the end for the company.
  • My price target for the stock a year from now is $3, so I shorted more yes...

Yesterday's Losses Reversed

Courtesy of Declan.

Bulls can be happy with today's progress. What weakness emerged today was reversed by the close, a change on yesterday's action where sellers dumped in the last few minutes of trading. Volume climbed to register an accumulation day.

The S&P finished at the 50-day MA, but beyond that there is plenty of room beyond that to run to the next level of resistance at 2,045. Technicals are net bullish.

The Nasdaq pushed off its 20-day MA and has another 50 points of maneuver before it gets to its 50-day MA.  Technicals are not yet net bullish, but they are close.

Sector Detector: Searching for solid support in the face of global headwinds

Reminder: Sabrient is available to chat with Members, comments are found below each post.

Uncertainty about the health of the global economy led investors to flee U.S. equities during Q3, primarily driven by worries about China's growth prospects and the Federal Reserve’s decision to not raise rates. Sure, there are plenty of real and perceived headwinds, but on balance it seems that a recession here at home is not in the cards. And when you consider sentiment and the technical picture, it appears that a continuation of Friday’s bounce is in store. The question remains as to whether the seasonally strong Q4 will be able to propel the bulls through levels of resistance that have built up.

In this weekly update, I give my view o...

Baxter's Spinoff

Reminder: Pharmboy and Ilene are available to chat with Members, comments are found below each post.

Baxter Int. (BAX) is splitting off its BioSciences division into a new company called Baxalta. Shares of Baxalta will be given as a tax-free dividend, in the ratio of one to one, to BAX holders on record on June 17, 2015. That means, if you want to receive the Baxalta dividend, you need to buy the stock this week (on or before June 12).

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.

"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 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.
