Abstract
With the power to influence investment decisions and provide market stability, stock price forecasting is essential to financial research. The use of machine learning techniques for prediction has gained popularity as technology has progressed. Researchers have proposed incorporating social media textual data to improve prediction accuracy. However, the efficacy of this strategy is still debatable because different kinds of textual information might produce varied results. Certain texts cause predictability to rise dramatically, while others cause it to fall. This research explores the use of machine learning techniques to predict stock prices using text data from social media platforms. Using Bag of Words (BOW) and Term Frequency-Inverse Document Frequency (TF-IDF) text representations, it assesses the effectiveness of Random Forest and Multinomial Naive Bayes classifiers. According to the investigation, Random Forest surpasses Multinomial Naive Bayes in terms of accuracy and robustness across a variety of datasets and text volumes, whereas TF-IDF consistently exceeds BOW. The analysis also reveals that Reddit's social media data has the most predictive value. These findings emphasize how important data quality and advanced text representation are to enhancing stock price forecasting models.
