Introduction
This project presents a comprehensive stock market prediction and analysis application built using Python and machine learning. It offers a user-friendly interface with powerful tools for technical analysis, sentiment evaluation, and stock price forecasting, making advanced investment tools accessible to both beginners and experts.
Key Features:
Interactive Technical Analysis:
Visualizes indicators like Bollinger Bands, MACD, RSI, SMA, and EMA to track trends and identify trading opportunities.
Financial Health Check:
Displays balance sheets, income statements, and cash flow data for assessing company fundamentals.
News & Sentiment Analysis:
Integrates real-time news and performs sentiment analysis using NLP to evaluate market mood and possible price impact.
Machine Learning Predictions:
Implements models such as Linear Regression, Random Forest, XGBoost, KNN, and Extra Trees to predict future stock prices.
User Interface:
Built with Streamlit, the web-based UI allows easy data input, visualization, and interaction.
Literature Review Insights:
Technical Indicators: Proven effective in forecasting stock movements ([Brock et al., Gençay]).
Media Sentiment: Shown to influence stock prices ([Tetlock, Ranco et al.]).
Machine Learning Superiority: Outperforms traditional models, especially with non-linear data ([Atsalakis, Patel et al., Qian & Rasheed]).
Problem Statement:
Traditional stock analysis methods are:
Time-consuming
Subjective and error-prone
Inefficient in handling fast-changing markets
The project addresses these issues by automating data retrieval, analysis, and forecasting using machine learning, enhancing accuracy, speed, and user accessibility.
System Architecture (Modules):
Data Retrieval Module:
Uses yfinance, stocknews, and alpha_vantage to gather stock prices, news, and financials.
Data Processing Module:
Cleans and formats raw data, calculates technical indicators.
Visualization Module:
Interactive charts and tables using Streamlit to display indicators and trends.
Prediction Module:
Trains and uses ML models (Linear Regression, XGBoost, etc.) to forecast stock prices.
News Sentiment Analysis Module:
Analyzes news article tone (positive/negative/neutral) using NLP techniques.
Financial Statements Module:
Displays annual reports and financial data using Alpha Vantage API.
User Interface Module:
Integrates all modules into a seamless, interactive experience with sidebar navigation and charting.
Evaluation & Results:
The application effectively analyzes and forecasts stock prices (e.g., Microsoft).
Supports short-term (5-day) and long-term (365-day) forecasting using regression models.
Provides clear, interactive visualizations of stock trends, indicators, and financial data.
Conclusion
The Streamlit application for stock price predictions and analysis serves as a comprehensive toolkit for investors and traders, empowering them with a user-friendly interface and a range of powerful features. By seamlessly integrating technical indicators, sentiment analysis, financial statement analysis, and machine learningmodels,thisapplication bridgesthegapbetween thecomplexitiesofthestockmarketandtheneeds ofusers.Through thevisualization oftechnicalindicators, integration ofstock newsand sentimentanalysis, fetching and displaying financial statements, and leveraging the power of machine learning algorithms for stock price prediction, the application equips users with valuable tools for informed decision- making.
