Last Updated on 10 February, 2024 by Rejaul Karim

In the intricate landscape of financial analysis, “When Buffett Meets Bollinger: An Integrated Approach to Fundamental and Technical Analysis” by Zhaobo Zhu and Licheng Sun offers a groundbreaking exploration into the amalgamation of fundamental and technical insights.

Published on February 24, 2019, with revisions up to July 30, 2021, this research, hailing from Shenzhen University and Audencia Business School, as well as Old Dominion University, stems from the intriguing implications of behavioral models. The study advocates for a holistic perspective, contending that jointly considering past price changes and firm fundamentals can efficiently unveil stock mispricing.

Strikingly, the proposed integrated approach not only yields substantial economic gains comparable to sophisticated strategies in existing literature but also maintains attractiveness even after factoring in transaction costs. Aligned with behavioral models, the research underscores the pivotal roles of limits to arbitrage and information asymmetry in elucidating the exceptional performance of this integrated analytical approach.

Abstract Of Paper

Motivated by the implication of prominent behavioral models that a joint consideration of past price changes and firm fundamentals could efficiently identify stock mispricing, we propose an integrated approach that combines fundamental and technical information. This integrated approach generates substantial economic gains, which are comparable to those of strategies double-sorted on characteristics related to high turnover and trading costs and state-of-the-art machine learning strategies in existing studies. The performance net of transaction costs is still attractive. Consistent with behavioral models, limits to arbitrage and information asymmetry play a significant role in explaining the super performance of this integrated approach.
