Obligacje zielone – trendy i perspektywy rozwoju

The purpose of the article is to identify changes on the green bond market. Using a sample of 1,202 bonds registered in the Thomson Reuters Eikon database, a statistical analysis using correlation measures, a test of signifiance of differences and basic descriptive statistics was carried out. The study finds an increasing share of corporate issuers and an increase in the diversifiation of the purpose of issuance and the currencies in which the bonds are denominated. There is a small correlation between maturity and the offered coupon or YTM. Compared to similar non-green bonds, they are issued for a shorter time, allowing for more flexible management of the investor’s portfolio.Celem artykułu jest identyfiacja zmian, jakie zachodzą na rynku obligacji zielonych. Na próbie 1202 obligacji zarejestrowanych w bazie Thomson Reuters Eikon przeprowadzono analizę statystyczną wykorzystującą miary korelacji, test istotności różnic oraz podstawowe statystyki deskryptywne. Przeprowadzone badanie wskazuje na coraz większy udział emitentów korporacyjnych, wzrost zróżnicowania celu emisji oraz walut, w których denominowane są obligacje. Wykazano niewielką zależność pomiędzy czasem zapadalności a oferowanym kuponem czy YTM. W porównaniu do podobnych niezielonych obligacji są one emitowane na krótszy czas, co pozwala na bardziej elastyczne zarządzanie portfelem inwestora

Zmienność giełdy papierów wartościowych po wprowadzeniu euro – analiza wybranych rynków

There were significant changes in the range of the information access observed during last two decades. It has determined growth of the international capital exchange. The effect of such situation is raising foreign investors’ participation in exchanges’ turnover. The monetary union in Europe indeed decreased FX risk in euro zone additionally. The goal of this paper is to analyze how the introduction of the euro influenced on stock exchange volatility. The hypothesis about the introduction of the euro stabilizing influence on euro zone stock exchanges volatility verification has been undertaken. The previous research does not fully confirm legitimacy of this opinion. The occurrence of such influence possibility has been proved, but the researchers are far from straight generalizations. The empirical analysis conducted in the article did not prove the hypothesis about the introduction of the euro stabilizing influence on euro zone stock exchanges with no doubts. There were some stock exchanges lowering their volatility after EMU accession analyzed in the paper, but we also find some others that such situation did not appear. Strong positive verification of Authors’ hypothesis cannot be done. However the hypothesis about the introduction of the euro stabilizing influence on euro zone stock exchanges volatility may be verified empirically. Although some other important stock exchange volatility determinants, strengthening or reducing the role of euro, may be omitted

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
