The present study focuses on the analysis of systemic risk in the American and European financial systems for the period from 20 August 2004 to 28 February 2014. The global crisis in 2007 has brought attention to the urgent need to understand the systemic risk issues and the stability of financial systems along with their actors. To assess systemic risk, Adrian and Brunnermeier (2011) advocated the use of conditional value-at-risk (CoVaR) methodology in integrating quantile regression. Instead of the value-at-risk (VaR), which is unable to detect systemic risk, we seek to use the CoVaR methodology to calculate the systemic risk levels of the United States and European markets. In the light of related findings, we conclude that the insurance sector contributes most to the systemic risk in the USA, while in the Eurozone, it is the financial services sector that is highly interconnected with systemic risk.

JEL classification: G 21, G24, G28Although Basel II fortified the first two pillars with market transparency enhancing Pillar III disclosures and encouraged the usage of major Credit Rating Agencies (CRAs) such as Moody's, Standard and Poor's, and Fitch as quasi governmental authorities to overcome asymmetric informational problems on risk and capital adequacy fronts of the global financial system, the recent global financial crisis has proven just the opposite. The banks and regulators were not in a position to truly assess the risk and capital adequacy frameworks of the global and domestic financial institutions based on the assessments of the rating agencies. To overcome the problem of informational asymmetry for the market participants, the Basel Committee on Banking Supervision set out new proposals for enhanced Pillar III disclosures in the areas of credit risks and capital reporting standards on the forefront of Basel III that would come into effect on April 1, 2016. This paper is a critical evaluation of the new reporting proposals of BCBS within the critical role of the credit rating agencies.

Purpose- The paper explores the correlation between investors’ sentiment, underpricing and performance over a period of 36 months of newly issued American stocks with a sample of 199 newly listed firms on NASDAQ and NYSE within the period of January 2015 to April 2021. IPOs listed on US stock exchanges have received little attention even though anomalies related to new stock issues are well documented. We aim to fill the existing academic gap. Methodology- We have hypothesized investor sentiment as the potential explaining variable inducing the anomalies observed and we extract this variable from the American Association of Individual Investors survey results per the nearest date of each IPO issue. We compute the returns in two separate timeframes. The Market Adjusted Initial Returns (MAIRs) are computed as the price change observed during the offer day, adjusted to the S&P500 index. We investigate long-term performance by calculating the Buy-and-Hold Abnormal Return (BHARs) of each IPO for a period of 36months. The company characteristics, which are age, proceeds, number of issued shares, venture capital backing status and economic sector, are retrieved from Thomson Reuter’s screens to control on IPO pricing. Then we use a regression model to see whether the predictor variable has an effect on the outcome variable. Findings- We found that the correlation between the bullish ratio and the MAIRs confirms results found in previous literature and no relationship between investor sentiment and long run performance have been observed. Conclusion- We conclude that on American stock markets, the existing underpricing can be explained by investors overreacting to new issues while findings relative to the long run performance contradict earlier research, as there is no evidence of underperformance among companies that went public between January 2015 and April 2021. Further research can be oriented toward understand why the documented poor performance related to IPOs no longer exists, as well as the particular characteristics of US markets which are favorable to the profitability of the new issues in the long-term.
