Although financial markets tend to be explained largely in quantitative terms, human behavior still plays a major role in driving price action, says Sheba Jafari, head of technical analysis for Goldman Sachs’ Securities Division. Jafari, who looks at historical patterns to predict movements in markets, explains: “In my opinion, the mere fact that we have the existence of [asset] bubbles indicates that markets are still run by emotions -- fear, greed and hope.” Also in the episode, Jafari discusses the impact of AI and machine learning on trading decisions and her own unlikely path from film studies to finance.
