The main objective of the paper is to measure the relationship between the market value disclosure of Egyptian Listed Companies, COVID-19 outbreak, and profitability. Multiple linear regressions, paired sample t-test, cross tabulations analysis and chi-square test are used to measure such a relationship, to analyze the effect of industry type on profitability and market value and to test for the significance of differences of market values and profitability before (for the period ended December 31, 2019) and after COVID-19 outbreak (for the period ended March 31, 2020). Results show that the market value and profitability of Egyptian Listed Companies before COVID19 outbreak differs significantly from the market value and profitability after COVID19 outbreak.
