We develop and implement methods for determining whether introducing new securities or relaxing investment constraints improves the investment opportunity set for prospect investors. We formulate a new testing procedure for prospect spanning for two nested portfolio sets based on subsampling and...

The COVID-19 pandemic and its impact on the stock markets in the Central and East European (CEE) countries have been investigated in many papers, but mostly from the perspective of the market connectedness and the spillovers. None of the existing researches addressed the potential changes in the...

Can stock price movements be traced back partially to interpersonal utility effects? That is, are shareholders also chasing nonfinancial goals apart from generating profit under risk that can be ascribed neither to findings of behavioral finance nor to traditional economical theories? Inspired...

This note is based on a recent confidence index introduced in the context of compensating probability factors for deviations of subjective probability measures from equivalent martingale measures. The index is adjusted for loss gain probability spreads, and it explains momentum in confidence. We...

In this paper, we build estimation error in mean returns into the mean-variance (MV) portfolio theory under the assumption that returns on individual assets follow a joint normal distribution. We derive the conditional sampling distribution of the MV portfolio along with its mean and risk return...

The steady-state turnover of a trading strategy is of clear interest to practitioners and portfolio managers, as is the steady-state Sharpe ratio. In this article, we show that in a convenient Gaussian process model, the steady-state turnover can be computed explicitly, and obeys a clear...

This paper investigates the impact of debt covenant protection on the cross section of equity returns with a firm-level covenant index and four sub-indices. We find that firms with weaker covenant protection (lower covenant index levels) earn significantly higher risk-adjusted equity returns...

This study analyzed activism that leads to a merger or acquisition (M&A) of a firm to see its benefits for the shareholders at the target firm as well as its acquirer. It used over thirty years of data to understand the impact of the activists’ demands of strategic significance for the firms....

We investigate investor behavior and firm performance related to corporate restructuring announcements using a database of Security Exchange Commission (SEC) filings by U.S. firms and web traffic on the SEC’s website. We find that abnormal investor attention positively predicts restructuring...

We present a dynamic equilibrium model to understand differences and interactions between informational and trading speed advantages. The model is a stochastic asynchronous game, with endogenous trading decisions and non-cooperation among agents, in a limit order market. We show that welfare and...
