Este artículo analizó los efectos financieros de la pandemia COVID-19 en las empresas farmacéuticas listadas en el índice de The New York Stock Exchange (NYSE). Se utilizó la metodología de estudio de eventos aplicada a una muestra de cincuenta empresas que conforman el sector farmacéutico del NYSE. Los resultados mostraron evidencia a favor de la eficiencia de este mercado financiero, lo que confirmó que detrás de todo gran fenómeno histórico radica un efecto financiero. Asimismo, pudo demostrarse que los rendimientos bursátiles de las empresas del sector farmacéutico presentaron resultados positivos ante los comunicados de la OMS, relativos al COVID-19.
This paper aims to analyse the financial impacts of the COVID-19 pandemic on the pharmaceutical companies listed in the New York Stock Exchange (NYSE) index. The event study methodology is applied to a sample of 50 companies that comprise the pharmaceutical sector of the NYSE. The results present evidence in favour of the efficiency of this financial market, thus confirming that behind all great historical phenomena lies a financial effect; it was possible to demonstrate that the market returns of pharmaceutical companies showed a positive return in the WHO reports on COVID-19.
