Abstract
As a matter of fact, feature importances are quite crucial for stock selection. This study investigates the application of feature importance analysis using a random forest model for stock price prediction, focusing on the semiconductor and public utility sectors. Given the inherent volatility and complexity of stock markets, traditional linear models often fall short in capturing non-linear relationships and interactions among variables. This research leverages machine learning techniques, particularly random forests, to identify key technical indicators that significantly influence stock performance. By analysing data from Yahoo Finance, the study incorporates a diverse set of factors, including momentum and volatility indicators, to assess their predictive power. The findings reveal that volatile sectors like semiconductors benefit from indicators such as short-term trends and volatility, while stable sectors like public utilities are more influenced by sector-specific conditions. These results provide a comprehensive framework for factor selection in stock analysis, highlighting the importance of a tailored approach based on sector characteristics. Future research should expand this analysis to include macroeconomic conditions and sentiment indicators, offering a more holistic view of the factors driving stock prices and enhancing investment strategies.
