Denise Shull of the ReThink Group helps hedge fund managers and traders improve their decision-making process by illustrating the power of emotions and the need to incorporate them into that process—as counterintuitive as it seems. Shull argues that emotions can reveal valuable information to traders about their biases and the reasoning that led them to make certain decisions. By combining emotional inputs with the rest of your process, investors can experience greater clarity when constructing strategies as well as develop a more holistic understanding of what makes markets tick. She also cautions against one of the worst trading mistakes an investor can make—over-trading.
