Teens are increasingly utilizing custodial investment accounts to participate in the U.S. stock market. Schwab reported nearly 300,000 custodial accounts for teens in 2023, a significant increase from around 120,000 in 2019. The rise in personal finance classes as a high school graduation requirement in many states is seen as a positive step towards enhancing financial literacy. Brokerages like Schwab, Fidelity, and Vanguard are experiencing a surge in custodial accounts for minors, with heightened activity observed during school breaks. Popular stocks among teenage traders include major tech companies such as Apple, Tesla, and Amazon.
