It focuses on trading strategies for financial instruements, leveraging sentiment analysis, genetic programming, and various machine learning models. A literature review provides context for the strategies employed. The study tests sentiment-based trading as a standalone approach and combines it with alpha generation via genetic programming. Additionally, models such as “LSTM Neural Networks”, “Random Forests”, and “XGBoost” are evaluated to assess their effectiveness. Comparative analysis are performed to identify optimal strategies for maximizing returns, improving investment decisions, and mitigating risks for individual investors.engTradingAISentiment analysisGenetic programmingMachine Learning Modelsmaster thesis203991540
