We test for possible explosive behavior (excessive disequilibrium) in COVID-19 infection in the top African impacted economies, given the sensitivity and fragility of stock markets to shocks. The study identifies two (2) separate explosive occurrences in Algeria and Egypt using the Generalized Sup Augmented DickeyFuller (GSADF) test. Furthermore, the study examines the influence of the COVID-19 infection’s explosive behavior on the stock markets of the countries, taking into consideration the disequilibrium occurrences. The COVID-19 infection’s explosive behavior had a negative but insignificant effect on stock returns, leading to an increase in riskiness. This outcome could be explained by the fact that the explosive incidents were transitory and could only have had a momentary impact on stock market returns absorbable overtime. More so, it suggests that investors may have adjusted to the shock of the COVID-19 infection prior to the two explosive occurrences, and that the development of the COVID-19 vaccine reassures for a near halt to the pandemic.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Продолжающаяся пандемия COVID-19 оказала значительное влияние на мировую экономику, правительства борются с распространением инфекции, поскольку она продолжает поражать почти все страны мира. В рамках исследования мы проверяем возможное взрывное поведение инфекции COVID-19 в наиболее пострадавших странах Африки, учитывая чувствительность фондовых рынков к потрясениям. Исследование выявило два отдельных случая выбросов в Алжире и Египте с использованием теста Generalized Sup Augmented Dickey-Fuller (GSADF). Кроме того, рассматривается влияние взрывного поведения инфекции COVID-19 на фондовые рынки стран с учетом неравновесных явлений. Взрывное поведение инфекции COVID-19 оказало негативное, но незначительное влияние на доходность акций, что привело к увеличению риска. Этот результат можно объяснить тем фактом, что инциденты были преходящими и могли оказать лишь кратковременное влияние на доходность фондового рынка. Более того, это предполагает, что инвесторы, возможно, приспособились к шоку и что разработка вакцины против COVID-19 дает надежду на то, что пандемия почти остановится.</p></trans-abstract><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>stock market</kwd><kwd>explosive episodes</kwd><kwd>GSADF</kwd><kwd>Africa</kwd><kwd>COVID-19</kwd><kwd>GSADF</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>фондовый рынок</kwd><kwd>эпизоды заражения</kwd><kwd>Африка</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Ashraf, B.N.
