| Summary: | The stock market is highly influenced by news and investor sentiment, making trend prediction
both challenging and valuable. This project develops a framework for stock price trend
prediction by integrating sentiment analysis of financial news with historical market data. News
headlines are cleaned and analyzed using VADER, TextBlob, BERT, and FinBERT to generate
sentiment scores, which are merged with OHLCV price data and enriched with lagged returns
and time-based features. Five machine learning models — Support Vector Machine (SVM),
Logistic Regression (LR), Random Forest (RF), XGBoost, and LightGBM — are trained and
tuned using walk-forward cross-validation. Their performance is evaluated using accuracy,
precision, recall, F1-score, and confusion matrices, with XGBoost achieving the best results.
Finally, a Power BI dashboard is built to visualize sentiment trends, market data, and model
predictions, making insights interactive and actionable. Results show that incorporating
sentiment features improves predictive performance, supporting data-driven decision-making
for investors and analysts. |
