In the following paper, the concept of risk was reproduced and calculated at the same time using the CAPM method (Capital Asset Pricing Model), a model of asset valuation. The study via this method, and therefore via the model, is the connection of the expected return of an asset with a risk size of the asset, also known as the beta coefficient (b), where the risk of co-fluctuation of a debt is expressed with the total market portfolio. More specifically, the first chapter describes the risk and the main types of risks faced by all companies, with reference to the CAPM model and its disadvantages. The second chapter then provides some general information on aviation, such as a brief overview of the historical context and development, with reference to the global market, partnerships and types of airlines. The third chapter introduces the airlines that were to be studied in combination with a reference to the stock market and a diagrammatic representation and analysis of the key indicators. Finally, in the fourth chapter, the application and analysis is performed through the calculation of the risk by determining the beta values (b) for the specific time periods, in order to ascertain the risk and its impact.
