How The AI Works

The AI equally weights seven new stocks every year.
New stocks are selected every March for the AI portfolio,
to coincide with release of 10-K Annual reports.

The AI is made entirely with code from the book.
The expectation is for slightly above S&P500 return,
and extreme volatility.

Building at AI Investor is intended as an educational tool
to teach simple Python code that may be useful
in informing personal investing choices.
