This study provides evidence of common bivariate jumps (i.e., systematic cojumps) between the market index and style-sorted portfolios. Systematic cojumps are prevalent in book-to-market portfolios and hence, their risk cannot easily be diversified away by investing in growth or value stocks....

This paper critically evaluates the literature on international unconventional monetary policies. We begin by reviewing the theories of how such heterogeneous policies could work. Empirically, event studies provide compelling evidence that international asset purchase announcements have strongly...

China is both a major trading partner of the United States and the largest official holder of U.S. assets in the world. The value of Chinese foreign exchange reserves peaked at just over $4 trillion in June 2014, but has since declined to $3.19 trillion as of August 2016. This very large decline...

In November 2008, the Federal Reserve announced the first of a series of unconventional monetary policies, which would include asset purchases and forward guidance, to reduce long-term interest rates. We investigate the behavior of shorts, considered sophisticated investors, before and after a...

This paper determines the most appropriate ways to model diffusion and jump features of exchange rates. Simulations show that intraday periodicity in volatility prevents conventional tests from accurately identifying the frequency and location of jumps. We propose a two-stage correction for this...

This paper characterizes the temporal pattern of trading rule returns and official intervention for Australian, German, Swiss and U.S. data to investigate whether intervention generates technical trading rule profits. High frequency data show that abnormally high trading rule returns precede...

This article first reviews methods of foreign exchange intervention and then presents evidence-focusing on survey results-on the mechanics of such intervention. Types of intervention, instruments, timing, amounts, motivation, secrecy and perceptions of efficacy are discussed

This paper argues that inferring long-horizon asset-return predictability from the properties of vector autoregressive (VAR) models on relatively short spans of data is potentially unreliable. We illustrate the problems that can arise by re-examining the findings of Bekaert and Hodrick (1992),...

This paper extends the genetic programming techniques developed in Neely, Weller and Dittmar (1997) to provide some evidence that information about U.S. foreign exchange intervention can improve technical trading rules' profitability for two of four exchange rates over part of the out-of-sample...

Using genetic programming, we find trading rules that generate significant excess returns for three of four EMS exchange rates over the out-of-sample period 1986-1996. Permitting the rules to use information about the interest rate differential proved to be important. The reduction in volatility...
