My Daughter (15 now) has a quite impressive portfolio now for her age
it started as a trip to Disneyland at 8 years old. The conversation came up that she could be (or anyone) can be a owner as a stock holder
She can home, and purchased two stocks. Her Financial Advisor was impressed enough that he sourced an actual old paper stock from the old times, I have no idea where he got it, but it still hangs framed in her room
That led to dividends, that led to her noticing other brand names (her next one was 3M) and she purchased a few of those stocks, more dividends, and she is slowly increasing her value
As she got the concept on the thought process of investing she switched to Mutual Funds, not as cool (or fun) as far as names go, but she actually grasps what they are, and the returns the last few years have been double digits. And it is cool to say that you own a particular company like 20th Century Fox
Grandparents and seeing her money management skills, and for Christmas, she usually gets the extra 100 for investments because they know they are not throwing money away
Also, I sat the kid down and showed her a compound interest chart with her specific numbers entered into it, and her eyes bugged out
She works part time here and there, she sends 10% of her take home to investing without thinking about it now
Get a good financial advisor that is more teacher than anything. He knocks the fees down as much as he can for her
