How do investors predict stock price movements? What forecasting models or strategies are available?

2. Machine Learning Models: Models such as Support Vector Machines (SVM), Artificial Neural Networks (ANN), and Random Forest learn from large datasets to capture complex relationships between stock prices and multiple influencing factors. 3. Deep Learning Models: Long Short-Term Memory (LSTM) and Transformer models—both deep learning architectures—are employed to forecast stock markets, providing data-driven support for investment decisions. LSTMs excel at capturing patterns and trends in time-series data, while Transformers leverage powerful parallel computation and efficient information extraction capabilities. 4. Economic Indicator Analysis: Economic indicator models forecast overall market trends based on macroeconomic variables such as GDP growth rate, interest rates, and employment data. 5. Technical Analysis Algorithms: Algorithms like moving averages, the Relative Strength Index (RSI), and Bollinger Bands analyze market behavior to identify recurring price patterns. 6. Hybrid Models: Combining different models improves prediction accuracy—for example, integrating LSTM and Transformer models to jointly capture short-term fluctuations and long-term trends. 7. Data-Driven Models: Trained on extensive historical data, these models yield predictions with a degree of objectivity and reliability.
