Abstract Text This thesis examines the relationship between the negative tone of CEOs and analysts in earnings conference calls and factors indicating firm-specific, respectively market-wide, extreme events. Earnings surprises deciles are used to define firm-specific extreme events, whereas the COVID-19 pandemic and the financial crisis provide periods of market-wide crises. The sample, consisting of 123,945 unique calls, reveals a convex, non-monotone relationship between negative tone and earnings surprise deciles and increased negativity levels during market-wide crises. Analyses of the impact of CEO negativity during extreme events on the market reaction and future firm performance reveal no event-contingent effects.
