Abstract

The analysis of stock market behaviour is still a very appealing topic because it can give investors information about where to invest their money. In this context, a dynamic investigaยญtion of Austria’s (ATX), Serbia’s (BELEX 15), Hungary’s (BUX), Croยญatia’s (CROBEX), Russia’s (IMOEX), Czech Republic’s (PX PRAGUE), Slovenia’s (SBITOP), and Poland’s (WIG) capital markets is carยญried out from September 18th, 2017, to September 15th, 2022. The results suggest that most indexes are far from being absent of long-term dependency, which may be interpreted as inefficiency; that is, throughout the Tranquil period, the stock market indexes SBI TOP (0.59), AEX (0.54), WIG (0.54), PRAGUE (0.53), and BELEX 15 (0.52) exhibit dependence over time. The CROBEX (0.47) and BUX (0.44) indexes indicate anti persistence, however, the Russian market shows equilibrium (0.49 โ‰Œ 0.0126), indicating that the ranยญdom walk hypothesis is not rejected. When we look at the behavยญiour of the markets under consideration during the Stress subpeยญriod, we see that persistence was significantly higher in the capiยญtal markets under analysis, except for the Russian market, which demonstrates some equilibrium. To conclude, we suggest that policymakers must take a comprehensive approach to improve the efficiency of international financial markets during times of stress due to uncertainty in the global economy and its influence on the memory properties of capital markets.
