Forecasting changes in stock rates may be possible with the assistance of brain activity in regions related to how people feel before making investment options. Researchers could accurately forecast market price changes based upon the typical brain activity among a group however stopped working when using only prior stock trends or people’s financial investment choices, according to new research study published today (March 8, 2021) in JNeurosci

Scientists have utilized the typical brain activity among a group to predict which videos will go viral and which crowdfunding campaigns will receive financing. In a new study, Stallen et al. investigated if this relationship encompasses a more complex and dynamic arena: the stock exchange.

Participants analyzed genuine stock cost patterns from 2015 as they decided if they wanted to purchase or offer the displayed stocks. During the task, the scientists used fMRI to determine activity in the nucleus accumbens and anterior insula, areas associated with looking for reward and avoiding risk, respectively. Using the group’s average brain activity in these areas, the scientists could forecast how a stock would act. Increased nucleus accumbens activity projection when a stock’s rate would increase the next day, while increased anterior insula activity projection when it would flip or alter instructions. Prior stock exchange trends and the participants’ own investing choices might not forecast stock rate dynamics.
