The big idea

There are AI tools that promise to make money trading stocks. The truth: most people who actively trade — even with AI help — lose money over time. Boring long-term investing beats AI trading for almost everyone.

Some examples

Promised: 'AI predicts the next big stock move.' Reality: nobody can reliably predict markets.
Promised: 'Beat the market with our AI.' Reality: less than 5% of professional traders consistently beat the market.
Reality: index funds (boring, slow) beat most active strategies over decades.
Reality: time in the market beats timing the market — every time.

Try it!

Look up the historical return of the S&P 500 vs the average individual day trader. The difference is huge. Talk to a parent about why long-term beats clever timing.

Practice this safely

Try this with a school, hobby, or family example where the stakes are low. Use the AI output as a draft you can question, not as the final answer.

Ask AI to explain stock trading in plain language, then underline anything that sounds uncertain or too broad.
Give it one detail from "AI Stock Trading: Why Most Teens Lose Money" and ask for two possible next steps plus one reason each step might be wrong.
Check AI trading against a trusted source, teacher, adult, expert, or original document before you use it.
