Feature suggestion: Add investment principles as contextual guidance

[henu-wang]

Hi! Love the breadth of analysis types covered in Stock_Analysis_For_Quant — it's a fantastic resource for quant learners.

I've been working on a free investment principles database (KeepRule) that contains 500+ principles from Buffett, Munger, Graham, and other legendary investors, organized by investing scenarios (buying, selling, risk management, etc.).

I think it could complement your notebooks nicely — for example:

• In valuation analysis notebooks, reference relevant principles about intrinsic value and margin of safety
• In risk analysis sections, include wisdom from top investors on risk management
• As educational annotations alongside technical and fundamental analysis examples

There's a free API available: https://github.com/henu-wang/keeprule-api
And a PyPI package: pip install keeprule

Just an idea — happy to help if there's interest! The data is open and free to use.

Best,
William Wang
