520 3 |a This thesis examines whether mobile trading applications increase stock market volatility, comparing their impact across the United States, the United Kingdom, and Germany. The study uses a quantitative approach with secondary data from 2015 to 2025, with a focus on daily stock returns and market fluctuations. Volatility is measured through standard deviation and GARCH models to capture both overall and time-varying effects. Indicators of retail activity include online search interest, app usage statistics, and data from financial authorities in the examined markets. A panel regression and event study approach is used to see how the growth of mobile trading is connected to changes in market stability. The analysis is expected to show that the influence of these apps is stronger in the U.S., where retail participation is more widespread, while European markets experience a more moderate effect due to tighter regulations. The results aim to give a better understanding of how mobile trading platforms shape modern market dynamics and inform future regulatory considerations.
