damianboh/portfolio_optimization ? reverse-engineered prompt

Build me a simple web app that helps someone optimize a stock portfolio.

I want it to let a user enter a list of stock tickers, choose how much money they want to invest, and then see a recommended portfolio split that aims for the best return for the risk. Show the main results in a clean way, like the expected return, risk, and a suggested allocation for each stock.

It should also let the user compare a few different portfolio ideas, like one focused on maximum growth and another that balances risk better. Add a chart or two so the results are easy to understand.

Make it feel polished and easy to use, with a straightforward interface and sensible defaults. If you need current market data or docs, look them up online.
