Keyword-based measures purporting to reflect investor sentiment, attention or uncertainty have been increasingly used to model stock market behaviour. We investigate and shed light on the narrative reflected by Google search trends (GST) by constructing a neutral and general stock market-related...

Although most of the empirical and theoretical asset pricing literature predicts a positive or no signi ficant relationship between idiosyncratic volatility and returns, Ang et al. (2006, 2009) find that high idiosyncratic volatility stocks have low returns and vice versa. We deliver further...

In this paper, I analyse whether the level of uncertainty in the financial markets affects the previously demonstrated relationship between media sentiment and stock market outcomes. I capture media sentiment by analysing the tone of the textual data from the New York Times stock market column...

Assuming that risk premiums are determined by failure risk, we present a stylized model of interactions among risk-proxy variables, external financing, and stock returns in which a common mispricing factor, involving operating profit and external financing, drives the following five asset...

Contrary to the theoretical principle that higher risk is compensated with higher expected return, the literature shows that low-risk stocks outperform high-risk stocks. Using a large-scale household dataset, we provide an explanation for this puzzling result that the anomalous negative...

We present a new model of asset prices in which investors evaluate risk according to prospect theory and examine its ability to explain 22 prominent stock market anomalies. The model incorporates all the elements of prospect theory, takes account of investors' prior gains and losses, and makes...

We investigate the impact of China's economic policy uncertainty (EPU) on the time series variation of Chinese stock market expected returns. Using the news based measure in Baker, Bloom, and Davis (2016), we find that EPU predicts negatively future stock market return at various horizons. This...

This paper investigates the predictive ability of international volatility risk for the daily aggregate Chinese stock market returns. We employ the innovations in implied volatility indices of seven major international markets as our international volatility risk proxies. We find that...
