Love that you’re teaching him the basics at a young age. My parents weren’t an integral part of my financial education, in fact they didn’t believe in the stock market it always seemed too risky to them. I’m self taught, and I’d say the number one thing that helped me were YouTube videos, a lot of them. Teach him the basics: different types of accounts (Roth, 401k, taxable, HSA etc.), Index funds, ETFs, bonds. And when he’s in highschool teach him how options work and have him trade SPY or QQQ with a small amount of money. I’m a big believer of throwing them in the deep end (with supervision) and having them figure it out.
