Billionaire Mark Cuban advises people to be careful buying into Wall Street's latest great idea:

Today, your investment advisors want you invest in things you have absolutely no fricking clue about and have pretty much absolutely no fricking ability to learn about.

They want you to diversify into Emerging Markets, Commodities, International Bonds, Munis, Real Estate Investment Trusts, ….and.. well, a lot of different “stuff”. . . .

Let me translate this all for you. “I want you to invest 5pct in cash and the rest in 10 different funds about which you know absolutely nothing. I want you to make this investment knowing that even if there were 128 hours in a day and you had a year long vacation, you could not possibly begin to understand all of these products. In fact, I don’t understand them either, but because I know it sounds good and everyone is making the same kind of recommendations, we all can pretend we are smart and going to make a lot of money. Until we don't."
