I'll create a stock market prediction application that analyzes historical data to predict potential profit/loss for the next day. This will include a dashboard for stock selection, historical data visualization, and prediction results.

This stock market prediction application includes:

1. Stock Selection: Choose from popular stocks to analyze
2. Historical Data Visualization: View price trends with an interactive chart
3. Prediction Engine: Get next-day price predictions with estimated profit/loss
4. Analysis Summary: See key factors influencing the prediction

Important Note: This is a demonstration application using simulated data and a simplified prediction model. In a production environment, you would:

1. Connect to a real financial data API (like Alpha Vantage, Yahoo Finance, etc.)
2. Implement a more sophisticated prediction model using machine learning techniques
3. Add more comprehensive technical analysis indicators
4. Include proper error handling and data validation

The application includes a disclaimer to remind users that stock predictions are inherently uncertain and should not be the sole basis for investment decisions.
