Influence of world stock markets on the development of the stock market in Ukraine

“International Financial Centres” (IFCs) such as London or New York are one of several contributing factors toward the continued economic success of their respective countries in the twentieth-century. Other countries have attempted to create their own IFCs with mixed successes. This study examines factors that might predict the appearance of IFCs and the differences in financial scale. Of particular interest is the debate between ‘bank-based’ versus ‘capital-based’ financial systems and how it impacts the growth and success of IFCs. Results suggest that bank-based systems are marginally more effective at promoting and benefitting from IFCs. Stronger financial market regulations are also positively associated with the growth of IFCs and the resulting benefits that they provide to the rest of the economy. Together, this suggests that the optimal policy mix to promote IFCs may involve some degree of government involvement beyond strictly maintaining free and fair financial markets for the private sector.

Working capital plays a vital role in shareholders’ wealth creation, yet there is a dearth of empirical studies on the relationship between working capital management and firm value in the South African economic environment. This study attempts to fill this gap by using Richards and Laughlin’s (1980) Cash Conversion Cycle theory to investigate the impact of working capital management efficiency and its separate components on firm value of South African firms listed on the Johannesburg Stock Exchange (JSE). Panel data regression methodology was used to analyze accounting data obtained from I-Net Bridge/BFA McGregor for 75 firms for the 10 year period, 2003 to 2012, to determine the nexus between WCM and profitability (proxied by return on assets). The key findings of the study are as follows: 1) there exists a significant positive relationship between firm value and both inventory conversion period and receivables conversion period; 2) the relationship between the cash conversion cycle and firm value is positive but insignificant; 3) there is a significant positive relationship between accounts payable deferral period (PDP) and profitability; 4) firm size and firm value are significantly positively related, and 5) there is a significant negative relationship between leverage and firm value.

Although some studies recently address the association between COVID-19 sentiment and returns, volatility, or stock trading volume, no one conducts an analysis to measure the impact of investor rationality or irrationality on the influence on countries and sectors’ returns.
This work creates a text media sentiment and combines its influence with the outbreak cases on the stock market sector returns of the US, Europe, and their main countries most affected by the pandemic.
This allows us to perceive the ranking impact of rationality or irrationality on country and sector stock returns. This work applies a random-effects robust panel estimation, with an M-estimator. This paper concludes that US returns are more sensitive to sentiment, and thus more prone to irrational factors than confirmed cases compared to Europe and that country factors influence the returns differently. In Italy and Spain as the most punished countries in Europe apart from the UK, present sector indexes return more reactive to verified cases, or rationality, namely, tourism, real estate, and the automobile (this last one in Italy).
The importance of this work resides in providing a new in-depth analysis of irrational behavioral metrics among countries, which allows for comparison. Moreover, it allows observing which sectors’ and which countries’ asset returns are most sensitive to rational or irrational expressions of events, allowing for arbitraging, financial planning for investors, decision-makers, and academia on an in and out of pandemic context.
