• FinTech Revolution: The Hidden Impact of Private Money Creation on the Cross Section of Stock Returns, with  Wenqiong Liu and Steven Wu. [SSRN] [Media Coverage]

  • Private money creation exerts a disproportionate impact on stock returns. This explains why the long-short strategies that buy non-speculative stocks and sell speculative stocks display predictable patterns. Causality is addressed using the recent FinTech revolution: The cross-sectional predictability is magnified by more than 100 percent after the exogenous shock. 

  • An earlier version of the paper was nominated as one of the top three papers competing for the 2023 EFMA Capital Markets Best Paper Awards at the 2023 EFMA Annual Conference

• Blinded by Lottery Preferences? Earnings News, Gambling-Motivated Trading, and Informational Efficiency, with Vidhi Chhaochharia, Jiaqi Guo, and Alok Kumar. [SSRN]

  • Lottery preferences of less sophisticated investors and their gambling-motivated trading limit the effectiveness of corporate disclosures and affects the informational efficiency of market prices. Although earnings disclosure reduces information uncertainty, opinion divergence between less sophisticated traders and arbitrageurs increases following earnings announcements.

• Understanding the Performance of Components in Betting Against Beta, Critical Finance Review, 2022, volume 11(1), 1-36. doi:10.1561/104.00000099  [CFR version]  [SSRN]

  • Betting against beta (BAB) can be decomposed into three investable components: Two cross-sectional components exploiting the beta anomaly attributable to stock selection and rank weighting scheme, and one time-series component with a dynamic net-long position due to “beta-parity”. Only the time-series component serves as the robust source for the profits of the BAB-type strategies.

• Correlation and the Omitted Variable: A Tale of Two Prices, Financial Management, 2021, volume 50, 519-552, with Zheyao Pan. doi:10.1111/fima.12333 [SSRN]

  • Correlation is “plagued” by firm size (the omitted variable) to exhibit a negative price. Once isolating the size impact, a hidden positive price emerges for the size-orthogonalized component of correlation.

• Investor Overconfidence and the Security Market Line: New Evidence from China, Journal of Economic Dynamics and Control, 2020, volume 117, with Kai Li and Youwei Li. doi: 10.1016/j.jedc.2020.103961 [SSRN]  

  • Investor overconfidence resolves the puzzle of a highly downward-sloping security market line (SML) in China: The slope of the SML becomes more “inverted” when investors get more overconfident. This dynamic overconfidence effect is intensified with biased self-attribution. As a general symptom of overconfidence in the cross section, high-beta stocks are also the mostly heavily traded. After accounting for trading volume, there is no longer the low-beta anomaly at the firm and portfolio levels. 

  • The paper won the Research Excellence Award at the 2018 New Zealand Finance Meeting

  • The paper was nominated as the Semifinalist in the Best Paper Awards (Category: Investments) at the 2019 FMA Annual Meeting

• Can Investor Sentiment Be a Momentum Time-Series Predictor? Evidence from China, Journal of Empirical Finance, 2017, volume 42, 212-239, with Youwei Li. doi: 10.1016/j.jempfin.2017.04.001  [SSRN] [Slides] [Data]

  • Investor sentiment in China exhibits a striking term structure: It serves as a strong momentum predictor in the near term (i.e., the monthly frequency) and gradually shifts to a contrarian predictor in the long run. This challenges the prevailing view that investor sentiment is a contrarian predictor of market returns at nearly all horizons.
