Exploring the Shadows of Irrationality in Stock Market Trading
Dr. Weik Li, Assistant Professor of Finance at Lee Kong Chian School of Business, seeks to illuminate how irrationalities impact stock market dynamics and shed light on behavioral financea field that harmonizes psychological theories with traditional economicto uncover why people might make irrational financial decisions.
This innovative study is a testament to Dr. Li’s commitment to understanding the complexities of behavior in financial contexts. With his recent publications, he has explored intriguing questions about investor perceptions of climate change risks and the implications of power asymmetry between optimistic and pessimistic investors on market prices.
In assessing how climate change might be factored into stock valuations, Dr. Li and his co-author suggest that because this risk is novel, investors may underreact to its impact. This oversight could potentially lead to a decline in stock prices for countries most vulnerable to climate-related risks.
By delving into the dynamics of power asymmetry between optimists and pessimists, he reveals how differing economic forecasts can influence market movements. Optimistic investors wield more influence because their reluctance to short stocks makes them more powerful than their pessimistic counterparts. When there’s high disagreement among investors about the economy's trajectory, the risk of overvalued markets increases due to the power imbalance between optimists and pessimists.
Dr. Li’s work exts further with an upcoming paper that explores Informational Content of Insider Silence. This research examines how corporate insiders' trading behaviors can offer insights even when they don't trade themselves. The study highlights that deviations from a typical trading pattern by insiderssuch as not following a routine selling strategycan signal significant events or information, providing investors with crucial market intelligence.
Dr. Li’s eavors are enriched by the dynamic and research-focused environment at Lee Kong Chian School of Business, where collaboration among faculty members fosters an atmosphere conducive to productivity for young scholars like himself. His first academic position following his PhD from Hong Kong University of Science and Technology in 2017 has allowed him to combine rigorous research with undergraduate teaching.
Teaching Financial Markets and Institutions, Dr. Li often encounters students seeking stock trading tips. Through insights gned from behavioral finance studies, he imparts practical advice on overcoming biases that traders might unknowingly hold. Overconfidencewhere investors underestimate market risksis a common pitfall, as is the disposition effectthe tency to sell winning stocks too soon while clinging onto losing investments for longer than necessary.
Dr. Li advises agnst frequent trading due to high costs and emphasizes the importance of patience in allowing stock prices to reflect their true value over time rather than reacting impulsively to short-term market fluctuations. He also cautions agnst being swayed by rumors or following the herd, recomming that retl investors consider purchasing index funds for a more balanced approach.
In recognizing his limitations as an individual investor compared to institutions with extensive resources and market expertise, Dr. Li steers clear of focusing on individual stocks. Instead, he mntns a diversified portfolio through indexed ETFs Exchange-Traded Funds, advocating for a boring investment strategy that prioritizes long-term wealth growth over short-term excitement.
His research underscores the importance of understanding behavior in financial marketsa field ripe with opportunities to uncover valuable insights and improve decision-making processes. Dr. Li’s dedication to this pursuit not only advances academic knowledge but also enriches the practical wisdom for investors navigating the complexities of global market dynamics.
