You have more leeway in setting the rules. Speaking of rules, I notice you've been breaking some lately. I always thought that the bond market, if excruciatingly boring, was at least logical. But, logical, yes. Unlike that impetuous rascal the Stock Market, who assigns absurd prices to stocks based on even more absurd expectations of future cash flows, everything I do conforms strictly to the laws of mathematics.
Interest rates go up, bond prices go down.
Rates go down, prices go up. I thought that the longer the bond's term, the greater the chance inflation will zap the value of its interest payments and principal. It will only get you in trouble. You're correct that long-bond yields are usually higher. In the most simplistic sense, yes.
