Article of the Week
Why Do We Make Bad Equity Decisions?
A behavioral economist at Cal Tech, Colin Camerer, is using decision neuroscience to examine why people make irrational stock market investment decisions. To do this, Camerer places undergraduate students in an fMRI and has them make trading decisions (buy/sell/hold) about a series of three artificial stocks. Participants were only permitted to hold one stock at a time and, after each trial, were given information about the stocks' performance. After receiving this price information, students were permitted to trade their held stock for a different one. Camerer found that the participants made poor trading decisions and were more likely to sell "winners" than "losers." In addition, Camerer found evidence of the "regret-repurchase" effect, whereby participants were less likely to re-buy a stock they had sold at a loss than a stock they had earned money from in a previous round. Camerer also found that the best traders--those who earned the most--had more activity in the insula than the lower-earning traders. Conversely, lower-earning traders showed more activity in the nucleus accumbens than higher-earning traders.
