Rachel Fox Earns Spot on Seventeen Magazine's Power Teens List as Day-Trading Actress

— -- When Rachel Fox is not appearing on TV and in movies, the 19-year-old is keeping busy as a stock day trader at her computer -- a skill that's earned her a spot on Seventeen magazine's Power Teens list.

"When I was 16 I was like, I understand a lot about, you know, companies," the "Desperate Housewives" actress told "Good Morning America" co-anchor Amy Robach. "And ... how they IPO on the stock exchange. I had this understanding and know-how. I had the skill of managing money...."

So Fox began trading with her own money that she made from acting. In her very first year of day-trading, Fox's returns beat the S&P 500.

"I have a couple different strategies," she said. "... With other investments, I will definitely pay attention to what's going on in pop culture a lot ... you can often take that information and kind of, arbitrage it before Wall Street [knows about it]. So, being a young investor, actually, has huge advantages and nobody even knows about that because pop culture and, you know, all the things that influences certain companies to do very well, is right at your fingertips."

Fox writes about all that she's learned on her blog, "Fox on Stocks," with the hope of helping others improve their financial literacy.

"... If you're curious about something, just let that drive you and just go with it," Fox said. "Just let the enthusiasm take you 'cause that's what I did and I was like ... 'There's no females in this industry or this world, but I'm gonna do it anyway.'"
