Sort of like an ETF or mutual fund but completely designed by you! Funny thing is, everyone with a brokerage account can actually buy your fund too (they just type in the name of your ticker symbol, created by you), and you can earn some money by running a great fund. You can pick your own symbol, put in your own investments and track your performance. Compete with other Youtual funds and attract followers (the more followers you have the more money you make!)
The site is completely free.
I thought this was a great idea to actually see the basics on how an ETF or mutual fund works, it's fun, you learn something in the process about trading, why not start your own youtual fund?
