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

In August 2017 I wrote “This will be my last post on the CAPE ratio.” I made it 16 months, which means I pretty much kept my word.

I was listening to Invest Like the Best when Cliff Asness said, “You do not want to make a career trying to beat the stock market based on whether it is cheap or expensive.” This sent me back to the drawing board.

Financial Crises Have Always Been "Made In Washington"

Submitted By Joseph Carson, Former Director of Global Economic Research, Alliance Bernstein

The Federal Reserve is facing the growing possibility of the third asset price bust in the last two decades. And each one has a "Made in Washington" label attached to it as policymakers have failed to use official rates to maintain financial stability while also inadvertently fueling excessive asset price gains by pursing expansionary policies to achieve their inflation-target.

At this time, polic...

Junk Bonds sending 2000 & 2007 Bearish messages again!

Courtesy of Chris Kimble.

This chart looks at Junk Bond Fund (PHDAX) and the S&P 500 over the past 25-years. Junk bonds sent bearish messages “before stocks peaked in 2000 & 2007.” Bearish divergences took place for 24-months in 2000 and 7-months in 2007, prior to stocks peaking and turning much lower.

This year Junk bonds have been sending a bearish message to stocks for the past 16-months, as another bearish divergence has been taking place.

Junk bonds and the S&P 500 are currently testing 9-year rising support currently. If both break below 9-year support, they would be suggesting that a long-term low in stock...

Bitcoin recently turned ten years old. In that time, it has proved revolutionary because it ignores the need for modern money’s institutions to verify payments. Instead, Bitcoin relies on cryptographic techniques to prove identity and authenticity.

However, the price to pay for all of this innovation is a high carbon footprint, created by Bitc...

Vilas Fund Up 55% In Q3; 3Q18 Letter: A Bull Market In Bearish Forecasts

By Jacob Wolinsky. Originally published at ValueWalk.

The Vilas Fund, LP letter for the third quarter ended September 30, 2018; titled, “A Bull Market in Bearish Forecasts.”

Ever since the financial crisis, there has been a huge fascination with predictions of the next “big crash” right around the next corner. Whether it is Greece, Italy, Chinese debt, the “overvalued” stock market, the Shiller Ratio, Puerto Rico, underfunded pensions in Illinois and New Jersey, the Fed (both for QE a few years ago and now for removing QE), rising interest rates, Federal budget deficits, peaking profit margins, etc...

Mapping The Market

Mistakes were Made. (And, Yes, by Me.)

Via Jean-Luc:

Famed investor reflecting on his mistakes:

Mistakes were Made. (And, Yes, by Me.)

One that stands out for me:

Instead of focusing on how value factors in general did in identifying attractive stocks, I rushed to proclaim price-to-sales the winner. That was, until it wasn’t. I guess there’s a reason for the proclamation “The king is dead, long live the king” when a monarchy changes hands. As we continued to update the book, price-to-sales was no longer the “best” single value factor, replaced by others, depending upon the time frames examined. I had also become a lot more sophisticated in my analysis—thanks to criticism of my earlier work—and realized that everything, including factors, moves in and out of favor, depending upon the market environment. I also realized...
