The authors analyze financial interactions between fundamentalists and chartists within a heterogeneous agent model, focusing on the role of fundamentalists stabilizing prices. In contrast to related studies, which are based on simulations and calculations, they analytically prove that the...

The authors analyze financial interactions between chartists with bounded leverage and fundamentalists within a heterogeneous agent model, focusing on the role of fundamentalists to stabilize prices. While many related studies are solely based on simulations, the authors analytically prove that...

Growing evidence shows that biological factors affect individual financial decisions that could be reflected in financial markets. Testosterone, a chemical messenger especially influential in male physiology, has been shown to affect economic decision making, and is taken as a...

Sentiment indices based on investor sentiment surveys attempt to measure the stock market sentiment. The literature on these indices focusses mainly on whether investor sentiment influences the financial markets or not. But the term “sentiment” has never been defined in the literature....

This paper examines post-revision return drift, or PRD, following analysts' revisions of their stock recommendations. PRD refers to the finding that the analysts' recommendation changes predict future long-term returns in the same direction as the change (i.e., upgrades are followed by positive...

Modern Portfolio Theory, the Capital Asset Pricing Model, and the Efficient Market Hypothesis are cornerstone concepts in both academic and professional curricula. In spite of their long history and reputation, the CAPM and its extensions do not yield satisfactory empirical results. We argue...

Based on prospect theory, we posit that security analysts' target prices function as a reference point for takeover bids and affect deal completion. Using a sample of US takeovers from 1999 to 2014, we find a negative relation between target prices for a takeover target and the chances for...

This study provides novel evidence that expert economic agents' work-related activities are systematically influenced by the time-of-day. We use archival data derived from time-stamped quarterly earnings conference calls together with linguistic algorithms to measure and track the moods of...

We investigate the causal impacts of air pollution on analyst forecast accuracy around earnings announcements. Using the air quality index in analyst workplaces, we provide direct evidence of the following. First, air pollution significantly reduces analysts' earnings forecast accuracy in...

Predictable biases in analyst forecasts, both conservative and optimistic, distort share prices, but only for firms with hard-to-forecast earnings---those with extreme past returns, credit risk, idiosyncratic volatility, and other attributes linked to 14 popular anomalies. The prevalence of...
