US Default: A Doomsday Portfolio

Talk about a Black Swan event--US default has only occurred five times in the country's history. In 1779 (government unable to redeem the continental currency issued during the Revolutionary War); 1782 (the Colonies defaulted on the debt they took out to pay for the war); 1862 (during the Civil War, the Union failed to redeem dollars for gold at terms stated by the debt contracts); 1934 (amid the Great Depression, FDR defaulted on the debt issued to finance World War I); and in 1979 (bureaucratic snafu resulted in missed interest on some small bills).

So let's admit that while it's not impossible, chances are that a full-on default is unlikely. That said, many of you have asked whether they should do something in their portfolios, "just in case." For most long-term investors, a well-diversified, balanced portfolio should see you through this period, just like it got you through a much scarier time in 2008-2009.

As my pal and MoneyWatch blogger Allan Roth says, "Investing is a long-term proposition and the more we speculate in the short-term, the lower our returns are likely to be...I'm sticking with my balanced portfolio of mostly index funds and CDs."

Yeah, I know...you still want to see my "Doomsday Portfolio". Please check with your advisor or broker to see if this makes sense for you, because it probably doesn't.
