We exploit a modification to Sustainalytics' environmental, social, and governance (ESG) rating methodology, which is subsequently adopted by Morningstar, to study whether ESG ratings are salient for stock pricing. We show that the inversion of the rating scale but not new information leads some...

This paper develops a general continuous-time evolutionary finance model with time-dependent strategies. It is shown that the continuous model, which is a limit of a general discrete model, is well-defined and if there exists one completely diversified strategy in the market, then there is no...

We use 92,632,873 daily returns for 33,010 US firms to establish the best forecasting model for realized idiosyncratic variances. Comparing forecasts from 10 different models, we find that the most popular models, the martingale and GARCH type models, perform worst. Using the...

In the light of the global financial crisis and sovereign debt crisis, this paper investigates the dependence patterns in 24 European equity markets from January 5, 2004 to July 1, 2016. We further examine whether these stressful events trigger contagion. Given that investors tend to behave...

We study how expectations of fund flows causally affect fund performance by exploiting a quasi-natural experiment in the Australian pension system where an unexpected policy change temporarily allowed fund withdrawals from a pre-specified date in the future. Using fractions of young members,...

Financial market anomalies are reviewed and categorized, and the “winners minus losers” anomalies - short-term reversal, Momentum and long-term reversion - are discussed. Literature on extensions to the Momentum anomaly, by incorporating market and fundamental information, is examined....

We find asymptotically optimal trading policies for long-term investors with constant relative risk aversion, in a multiple-assets market where expected returns and covariances are constant, and the execution price of each asset is linear in the trading intensities of all assets. Trading towards...
