Most "AI picks stocks" demos are fiction.
You ask a chatbot for undervalued companies, it hands you five tickers, and they sound reasonable. AAPL. MSFT. A bank you've heard of. It feels like analysis.
It isn't.
The model is reciting names from its training data. It has no idea what those companies trade at today, what their P/E is this quarter, or whether they're even still profitable. The numbers it quotes are frozen in time, and half of them are made up.
So I ran a different experiment. I gave Claude a real stock screener as a tool, handed it an actual market goal, and let it do the filtering itself.
