This study suggests a novel approach for decomposing an options order imbalance based on trading motives using put-call parity. The options order imbalance is separated into two components: one that contains arbitrage trading and one that does not. Intuitively, the proportion of the former...

We use arbitrage activity in equity, fixed income, and foreign exchange markets to characterize the frictions and constraints facing intermediaries. The average pairwise correlation between the twenty-nine arbitrage spreads that we study is 22%. These low correlations are inconsistent with...

We propose a new approach to modeling informed order flows. Our approach generalizes arbitrage pricing to incorporate both information and demand effects, giving rise to a new quadratic factor model of price impacts. Our approach offers two fresh insights into the economics of informed trading....

This study uncovers a unique dividend-tax arbitrage strategy that provides high-bracket investors the opportunity to circumvent taxation on dividend income. As the first comprehensive analysis, we examine diverse investor types, implementation techniques, and implications on stock prices....

This paper specifies a simulated convertible bond arbitrage portfolio to characterise the risks in convertible bond arbitrage. For comparison the risk profile of convertible bond arbitrage hedge fund indices at both monthly and daily frequencies is also examined. Results indicate that...

We propose a novel no-arbitrage framework, which exploits convex asset pricing constraints to study investors’ marginal utility of wealth or, more generally, Stochastic Discount Factors (SDFs). We establish a duality between minimum dispersion SDFs and penalized portfolio selection problems,...

In this paper, we consider an optimal stopping problem that addresses model uncertainty. Model uncertainty is the uncertainty affecting the model assumptions, e.g., the assumed form of the probability distribution, the parameters embedded in the probability distribution. The result presented in...
