Offshore Mutual Fund
  
You know how big corporations and international drug dealers use offshore banks and shell companies domiciled in obscure island nations to avoid undue tax and regulatory security? An offshore mutual fund brings that concept to the masses.
These funds are based outside the U.S., putting them outside U.S. regulations. Maybe you want to invest in kangaroo wrestling or the Consolidated Opium Growth Fund. An offshore mutual fund might be the right direction for you.
Typically, the main benefit from these investment vehicles are as a tax haven. Since they're outside the jurisdiction of U.S. regulators, you don't have to pay American taxes on the gains. However, there might be restrictions on getting your money back to the U.S. without incurring a tax bill. But maybe you can look into buying a new house on that obscure island nation...right next to the international drug dealer.
