What Others Are Saying About TeenVestor

"Good information in an accessible, and unlike many books aimed toward the younger market, unpatronizing manner."



“TeenVestor serves as a great introduction to investing and the fundamentals of financial markets for teens… One of the greatest aspects of TeenVestor is that Modu has written the book in a tone that teens can relate to. He has taken a wide array of financial concepts and presented them in such a way that today’s teen can easily appreciate. Modu uses examples that are simple to understand and gives practical advice that any “Teenvestor” can start applying right away.”   

— Jack E. Kosakowski, President & CEO, Junior Achievement USA


“As both the CEO of Investopedia and the father of a teenage son, I thoroughly recommend this book to both teenagers and their parents. The state of financial education in the U.S. is woeful. Schools are failing and it is up to our teenagers and parents to enable their kids to become Teenvestors. The authors’ use of worksheets, real-life examples and easy-to-use format help readers gain more knowledge than after their first finance class in college, but in a much easier learning format. Concepts such as diversification, compounding, EPS and socially responsible investing were particularly well done, as well as advice for parents on managing money and teenage investing. Despite having an MBA in Finance from Wharton, I was able to gleam more than a few take-aways. As both an investor and the parent of investors, it is a must read.”

— David Siegel, CEO, Investopedia


“Written especially for teenagers, although it’s actually a good basic resource for any age… Good, solid (not dumbed down) explanations of investment basics. I like this book because it encourages parents to come along for the ride and learn about investing, too.”

— Money


"Teens and first-time investors, this is your moment! No one is going to care more about your financial future than you, and because you have time on your side, you are in the best position to make the most of that future. Thanks to a whole host of new, affordable and easy-to-understand online investing options, there has never been a better time for the 'little guy' to take charge of his/her investments. Mr. Modu's book offers clear, concise and actionable information to help get you on the right path."

— Donato "Don" Montanaro, Jr., CEO, TradeKing Group, Inc.


 “In-depth and sophisticated… [TeenVestor] doesn’t assume its readers have had prior exposure to investing or easy access to money… Teens and parents will appreciate the detailed treatment of investing strategies.”

— Morningstar


“When it comes to saving and budgeting, these are habits that are necessary to develop at an early age as they are crucial to creating a healthy financial future. As a teen, your ability to start saving money now, no matter what amount, will help pave the way for future stability and allow your money to grow faster through compound interest.  TeenVestor is an excellent book that will set you on the path to being a prudent saver and a wise investor.”

— Luvleen Sidhu, Co-Founder and Chief Strategy & Marketing Officer, BankMobile


“TeenVestor is another excellent resource for learning not only the basics of investing in stocks, mutual funds, and IRAs, but also the workings of the economy.”

— Barron’s


“Psst. Find this website on the internet and bookmark it. Just don’t let anyone know you’re using it. It’s supposed to be for kids. If you want to learn about investing, this is the place to go. It’s for teens, but if you won’t tell, we won’t either. This is good stuff.”                                                                                       — Independent Tribune


“The authors explain the basics of investing… how to understand the stock market, and how to evaluate and choose stocks for the long-term…Accurate, objective, and helpful.”

— School Library Journal
