In this paper, we present a comparative investigation of the multifractal properties of seven Central and Eastern European (CEE) stock markets using recent financial data up to August 2018 by employing seasonal and trend decompositions before applying multifractal detrended fluctuation analysis. We find that stock indices returns exhibit long-range correlations, supporting the idea that the stock markets in question are not efficient markets and have not reached a mature stage of market development. The results of the paper are of interest to investors looking for opportunities in these stock exchanges and also to policy makers in their endeavour of realizing institutional reforms in order to increase stock market efficiency and to support the sustainable growth of the financial markets.

Despite the importance of high-growth firms (HGFs) for job creation, innovation, and economic development in transition economies, current knowledge on the role of financial decisions in explaining their profitability is limited. The aim of this paper is to examine the relationship between working capital management and firm profitability. Using a panel data set on HGFs from Central, Eastern, and South-Eastern Europe during the time span 2006–2015, we found an inverted U-shape relationship between working capital level and firm profitability. Our findings indicate that HGFs should find and maintain the optimal working capital level that maximizes their profitability. Our results proved to be robust when we employ different methodology (quantile regression), different sub-samples as well as alternative measures of profitability and working capital management. The study highlights the importance of short-term financial decisions in enhancing HGFs’ profitability, with significant implications for academics and practitioners. We contribute to the extant literature by providing empirical evidence on the existence a concave relationship between working capital level and firm profitability for a cross-country sample of firms.
The objective of this paper is to study the spillover effects between energy markets and stock markets with emphasis on the significant crisis periods of the last 15 years, the period of the financial crisis that officially started in 2008, the pandemic period, generically called COVID-19, and the recent confrontation in Eastern Europe. Understanding the volatility transmission mechanisms between the energy and capital markets and also from the energy markets back and the spillover effects that result is very important. We use multivariate GARCH models to highlight a spillover effect between energy commodities and equities in Central and Eastern Europe. The highest correlations are recorded for CEE stock markets with electricity and Brent, and the lowest for CEE stock markets with gas. The biggest symmetric shocks between energy and CEE stock markets occurred during the COVID-19 pandemic. In contrast, the biggest asymmetric shocks occurred during the financial crisis (for gas) and the Ukrainian invasion (for Brent). We also find that volatility is more sensitive to its lagged values in the marketplace than it is to new information. The impact and contagion of shocks caused by the oil market are greater than those of other energy markets.

The increasing growth of soccer economy is delivering new challenges for prospective investors in terms of stock price volatility. Such challenges are rooted in behavioral finance and efficient market hypotheses. Given this, the aim of our paper is to test the link between sport performance and correspondent stock price for the Italian listed football clubs (Juventus, Lazio, AS Roma). Our results suggest that soccer wins are likely to have a positive impact over stock price. This impact is more pronounced for local stocks and thus the findings have policy implications for emotional investors.
