In volume 3 of CFAI readings, page 341, “we could use bond#2 as our controlling position” because this security has the shortest duration. Since the rebalancing ratio is calculated to be more than 1(111945/82579, new numbers given in errata), I thought that buying bond 1(longest duration) as our controlling position. Also referring to Schweser 3 P28. Pls correct me if I am wrong.
buying the bond with the longest duration will require the lowest dollar outlay to increase dollar duration to the desired amount. But you can purchase any bond in the portfolio to raise the dollar duration to the desired level. In this case, they choose the smallest duration bond by the looks of it.
Actually short duration securities are preferable to be used as a controlling position because of their liquidity.
Still confusing, in order to raise the dollar duration, buy longest duration bond or sell shortest duration bond or either way? ???
ggb, as striker said - you can do whatever works, but liquidity and dollar outlays can guide your choice. I think.

does anyone know how exactly this works? Meaning, how do I determine how many bonds to buy or sell. When it’s across the portfolio, it’s easier. How about when I choose to buy or sell a particular bond?
