Value-at-risk (VaR) is a useful risk measure broadly used by financial institutions all over the world. VaR has been extensively used to measure systematic risk exposure in developed markets like of the US, Europe and Asia. This paper analyzes the accuracy of VaR measure for Pakistan's emerging...

Volatile events in the stock market such as the 2010 Flash Crash have sparked concern that financial markets are "rigged" in favor of trading firms that use high frequency trading ("HFT") systems. We analyze a regulatory change implemented by the SEC in 2007 by examining its effect on a key...

The time evolution of prices and savings in a stock market is modeled by a discrete-delay nonlinear dynamic system. The proposed model has a unique and unstable steady-state, so its time evolution is determined by the nonlinear effects acting out of the equilibrium. We perform the analysis of...

We find that the weather induced local employment growth surprises are positively related to the cross section of future local stock returns for up to three months without subsequent reversals. In comparison, neither weather nor reported employment growth can predict future returns. This return...

We characterize the response of U.S., German and British stock, bond and foreign exchange markets to real-time U.S. macroeconomic news. Our analysis is based on a unique data set of high-frequency futures returns for each of the markets. We find that news surprises produce conditional mean...

We provide a simple and intuitive measure of interdependence of asset returns and/or volatilities. In particular, we formulate and examine precise and separate measures of return spillovers and volatility spillovers. Our framework facilitates study of both non-crisis and crisis episodes,...

This paper examines the relationship between stock market development and economic growth in case of Argentina's economy. Apply Granger causality and exogeneity tests based on VEC (vector error correction) models with monthly data covering the period 1993:1-2010:8. The results show that the...

We investigate how the relative contribution of external factors to stock price movements varies with the degree of financial development. We find that financial development makes stock markets more susceptible to external influences (both financial and macroeconomic). Interestingly, this effect...

Im Rahmen der Aufarbeitung des Wirecard-Skandals wird ebenfalls eine Änderung der Kriterien zur Aufnahme in den deutschen Leitindex DAX diskutiert. Die bislang von der Deutschen Börse vorgelegten Vorschläge zur Reformierung des DAX gehen in die richtige Richtung, sind aber nicht weitreichend...

We provide an empirical framework for assessing the distributional properties of daily speculative returns within the context of the continuous-time jump diffusion models traditionally used in asset pricing finance. Our approach builds directly on recently developed realized variation measures...
