-I bonds I've bought for the past 12 years or so. My older ones were like 3.6% fixed plus inflation. I was laughed at when I bought 60,000 of that stuff that year, but he who laughs last laughs best. I even bought on a credit card at the time off treausrydirect, so made a killing on that. Now the limit is $10k/year.
-30 year TIPS : Really aweful now. The real yield is about 2% on the secondary market. I have a bunch of this stuff when it was yield a real rate of 3%, so I could sell those bonds for a big premium today. I think if you go below 27 years on the secondary market you will get a negative real yield and that is before taxes. The next primary auction for this will be February 2013. I'm gonna assume a really low real yield, maybe .2%? As long as the real yield is positive, this will be my roth ira conversion money, which will be $5500 next year.
-EE bonds : - Another interesting investment. If you hold for 20 years, you are guaranteed to double your money. So in essence you will get 3.53% tax deferred interest. Intersting put option of inflation really takes off since you could sell after one year. You can only buy $10,000 in a year of this.
-Gold : Not sure what gold does, but just sold a bunch of my gold coins which I was given as a gift when I graduated medical school. Pretty poor performance this year. I think I sold each coin for $1800, but today worth $1700.
-Stock Market : Pretty poor performance since 2000. About 2%/year after fees, which is less than the rate of inflation. So a 12 year peroid of holding the s and p 500 doesn't guarantee you beat CPI inflation.
