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

This stat from @SentimentTrader blew me away:

“The S&P 500 fund, SPY, has been up at least 0.5% for 5 straight days. That’s tied for the longest streak since its inception.”

I wasn’t taken aback because of how strong the markets have been recently, but that streak of five days sounded really small to me. I almost couldn’t believe it was right. But after looking at the data, the shock wore off.

The S&P 500 has gained >0.5% on 28% of all days (going back to 1993), so the likelihood of...

Financial Stress Is The Second Global Crisis We Are Facing

By Jacob Wolinsky. Originally published at ValueWalk.

No matter what level of income you’re on, a global financial crisis can be extremely stressful for anyone. It boils down to one simple reason; uncertainty.

Humans hate uncertainty. In fact, a study in 2016 showed that humans find uncertainty even more stressful than knowing something bad is definitely going to happen. Uncertainty causes a huge amount of stress on the human body, and i...

Here's Why QQQ and Large Cap Tech Stocks May Rally Another 10%!

Courtesy of Chris Kimble

The long-term trend for large-cap tech stocks remains strongly in place.

And despite the steep rally out of the March lows, the index may be headed 10 percent higher.

Today’s chart highlights the $QQQ Nasdaq 100 ETF on a “monthly” basis. As you can see, the large-cap tech index touched its lower up-trend channel support in March at (1) before reversing higher.

It may now be targeting the top of the trend channel at (2), which also marks the 261.8 Fibonacci extension (based on 2000 highs and 2002 lows). That Fib level is $290 on $QQQ.

If so, this upside target for $QQQ is still 10% above current prices. Stay tuned!

Golds quick price move increases the odds of a correction

Courtesy of Read the Ticker

Every market corrects, maybe profit taking, maybe of allowing those who missed out, to get in!


The current open interest on the gold contract looks to high after a very fast price move, it looks like 2008 may be repeating. A quick flushing out of the weak hands open interest may take place before a real advance in price takes place. The correction may be on the back of a wider sell off of risk assets (either before of after US elections) as all assets suffer contagion selling (just like 2008).

This blog view is a gold price correction of 10% to 20% range is a buying opportunity. Of course we may see  a very minor price correction but a long time correction, a price or time is correction is expected, we shall watch and...

The COVID 19 pandemic is, predictably, worsening again in much of the US. Only the Northeast, and to a lesser extent some Midwestern states, have been consistently improving. And that trend could also reverse as those states fully reopen.

The problem in the US seems to be widespread public resistance to recommended practices of social distancing and mask wearing. In countries where these practices have been practi...
