Abstract

This study aims at measuring the impact of the Cambridge Analytic scandal on the profitability of Facebook shares between 2017/2019 using the capital asset pricing model. To reach this goal, we relied on weekly adjusted data for both the Facebook and NASDAQ-stock prices, Effective federal funds rate. We then estimated the beta β coefficients for three periods (pre-scandal period) and two periods after-scandal period, using the Simple linear regression model. The research concluded that there was a statistically significant relationship between return and risk. The results also showed the negative impact of the Cambridge Analytica crisis on the profitability of Facebook shares.
