I empirically study price jumps using high frequency data comprising 5-, 10-, 15- and 30-minute market data on the main indices from the Prague, Warsaw, Budapest and Frankfurt Stock Exchanges for June 2003 to the end of 2008. I use two definitions of price jumps: the price jump index and...

We analyze the impact of Eurozone/Germany and U.S. macroeconomic news announcements and the communication of the monetary policy settings of the ECB and the Fed on the forex markets of new EU members. We employ an event study methodology to analyze intra-day data from 2011-2015. Our...

We analyze time-varying exchange rate co-movements and volatility spillovers between the Czech koruna, the Polish zloty, the Hungarian forint and the dollar/euro from 1999 to 2016. We apply the dynamic conditional correlations (DCC) model and the Diebold Yilmaz spillover index to examine the...

We analyze comovements among three stock markets in Central and Eastern Europe and, in addition, interdependence which may exist between Western European (DAX, CAC, UKX) and Central and Eastern European (BUX, PX-50, WIG-20) stock markets. The novelty of our paper rests mainly on the use of...

Under the CAPM assumptions, the market capitalization weighted portfolio is mean-variance efficient. In real world applications it has been shown by various authors that low risk portfolios outperform the market capitalization weighted portfolio. We revisit this anomaly using high-frequency data...

During the recent financial crisis, there was a dramatic spike, across all industries, in the volatility of individual firm share prices after adjustment for movements in the market as a whole. In this Article, we demonstrate that a similar spike has occurred with each major downturn in the...

This paper derives two new improved risk metrics LAPVaR and LAPSF. Traditional VaRDeltaNormal valuation exaggerates market and liquidity risks to the point it could be larger than the actual portfolio value. Put VaR – PVaR – as well as Put Shortfall – PSF – uses option theory to solve...

This paper presents an alternative method to calculate analytical VaR and Expected Shortfall – ES – using the Black & Scholes put option formula, Markowitz diversification concept of the covariance-variance matrix and tail price return histograms to calculate volatilities and correlations at...

Asian VaR and coherent Asian Expected Shortfall are an improvement over current methods, measuring more accurately financial portfolio market and liquidity risks. Risk to LIQUIDATION</I> means every day a portion of portfolio assets-i (i = 1 to H_i) is unwound; thus the final unwind price is the sum...
