Assessing the impact of the COVID-19 pandemic on stock prices in selected sectors

The aim of this paper was to try to evaluate and map the stock price trends of oil and healthcare companies - from 2019 to 2024 and to find out how the COVID-19 pandemic has affected the increase in stock prices and whether there is a linear relationship between these companies. Correlation analysis was used to analyze the data - the result of the correlation coefficient showed that there is only a weak linear relationship between the companies. For the purpose of this paper, Pfizer and Moderna were selected as healthcare companies and Saudi Aramco and Chevron as oil companies. Pfizer and Moderna were the main developers of the vaccine and Saudi Aramco and Chevron are one of the largest oil companies in the world. The companies did not influence each other. Price data was obtained using content analysis and projected onto graphs. During the period under review, the curve recorded both increases and decreases for the selected companies. One of the main factors for the stock price development was the COVID-19 pandemic. The pandemic had a strong impact on the stock development of both companies. During this period, there were price increases. The biggest limitation of this paper was the event of COVID-19 pandemic which affected the stock price development and hence the results were affected.
