A clean up is needed for laymen like me, who understand zilch of all this. What is "yield to maturity of the bond"? What is "derivative of value"? I suggest using clear TeX formulas with a list of all the variables and either brief explanations of the terms or links to articles which explain them. It's no problem keeping some verbal explanation, but a formula has the great advantage of not confusing the meanings of "times" (multiplication, occurrence, epochs...).

Yup, this need at least to be put in equations. You can look up elasticity to general to derive the meaning of this term. --Cryout 21:43, 15 October 2007 (UTC)
