Build me a modern investment tracking web app where I can search a stock ticker, see its price history on a chart, read the latest company news with a simple sentiment summary, and then add that stock to a personal portfolio with my purchase date and quantity.

I want the app to automatically calculate my gain or loss for each holding and for the whole portfolio, including using the right historical price if I entered an older buy date. Please also add an AI powered section that gives a BUY, SELL, or HOLD style recommendation with a confidence score and an overall portfolio health score. If the AI key is missing, show a friendly fallback recommendation instead.

Make it look sleek and modern with a dark glassy design, smooth animations, and a clean dashboard feel. Use real stock data, keep it responsive, and make the main pages feel polished and easy to use. If you need current API details, look up the latest docs online.
