Issuers (having a greater level of market capitalization) release a present report on IoA. On the other hand, these outcomes need to become confirmed on a bigger investigation sample, which will only be doable just after more months of pandemic. 6. Conclusions The principle goal of this paper was an examination the capital market reaction (around the example of WSE) for the details offered by the issuers, within the type of a current report on IoA. The investigation contribution to the state of knowledge inside the field from the implemented paper is an attempt to verify how the market place will react to such facts in a scenario when the specter of a critical economic crisis hangs more than it, which was caused by the pandemic of Vorinostat Autophagy COVID-19 for the duration of in 2020. Finding from the abovementioned references by issuers listed on the WSE, 55 cases of IoA announcements have been finally qualified towards the study sample. For each and every of them, a seven-day symmetrical occasion window was constructed, covering the day of publishing data in regards to the IoA and three days preceding and following that day. The obtained research final results, verified with all the non-parametric tests, demonstrated no statistical significance with the AAR for each of your analyzed days in the occasion window, except for two instances: WIG20 day t0 and mWIG40 day t+3 . Sadly, a statistically important market place reaction in these situations was associated to a really little study sample. Based on the lack of statistical significance of your vast majority of obtained results, the key hypothesis adopted at the starting of this study ought to be rejected. Nevertheless, the lack of statistically substantial AR on the days following the disclosure of data on impairment of assets allows to indicate a unique industry reaction within the conditions on the economic crisis caused by COVID-19 as in comparison with the a single observed in prior years. Lack of marketplace reaction about current reports informing about IoA is somewhat surprising. Through the COVID-19 pandemic, investors could discount quite a few different unfavorable informations in the environment and ignore absolutely negative data concerning the reduction of recoverable quantity of issuers’ assets. The situation is unexpected due to the fact, within the preceding years, there was a unfavorable reaction of WSE investors to IoA (Lisicki 2021). This truth manifested itself inside the occurrence of statistically important negative AAR on the day of publishing the present report about IoA and around the following day. It might therefore be assumed that the COVID-19 pandemic made investors be much significantly less Exendin-4 Cancer sensitive to other (than about COVID-19) information on the market place. The research undertaken in this short article enables globe researchers to think about the attainable occurrence of a unique marketplace reaction (or its total absence) towards the upcoming for the capital markets info during the COVID-19 pandemic. The obtained final results constitute a particular contradiction on the study benefits obtained by prior researchers. For this reason, they really should be treated as a sort of invitation for additional scientific exploration. Nonetheless, at this point, some limitations in the study must be pointed out, which have been a significant reduction in the study sample (from 76 to 55 circumstances) because of the presence of coexisting events in the occasion window. However, an author using the occasion analysis methodology have to often take such a scenario into account. The obtained benefits could constitute the basis for undertaking analysis around the verification of investors’ sentiment to.
