Anyone else would have expected the wording "the cheapest to deliver bond is priced...with duration..."?? Instead they speak of futures contract. So why applying the conversion factor in the solution?作者: mar350 时间: 2011-7-13 16:48
When short delivers the actual bond to the investor of a long futures contract , sometimes there could be many different alternative securities that could be delivered , as specified in the terms of the contract. Usually short is allowed to deliver an available bond of their choosing that meets the specs. This is called CTD , and it has a conversion factor. I am sure you know all this from previous lvl s ?作者: bpdulog 时间: 2011-7-13 16:48
OK, just to make it clear: 2 different wordings - first one like in the original text:
"the futures contract it would use is priced at €130,000 and has a duration of 9.35. Assume that the conversion factor for the futures contract is 1.06"
"the cheapest to deliver bond to the futures contract it would use is priced at €130,000 and has a duration of 9.35. Assume that the conversion factor for the futures contract is 1.06"
first one i wouldn't use the conversion factor in my calculation, while in the second one i would........but CFAI also does in first wording.作者: bodhisattva 时间: 2011-7-13 16:48
What is the futures contract on? -- it is on a bond.
what is the bond that would be delivered -- the cheapest to deliver bond.
so in option 1) even though they do not specifically mention it -- that is how it is...
not sure if a futures contract on a bond to be delivered is on a fixed bond. It is upto the "seller" of the bond to decide which bond he would deliver - and more often than not it would be the CTD bond.

They have mixed up the terms . The CTD bond has a conversion factor , while the futures contract may have a number of alternative bonds that COULD be delivered , each having its own conversion factor .
They used the CTD bonds conversion factor and just short-formed it into the "conversion factor for the futures contract" .
The actual CTD to be delivered by the short is only known the day before delivery ( depending on the richness of the alternatives) , so you certainly do not know the conversion factor or indeed the price of the bond, when you buy the futures contract.作者: cityboy 时间: 2011-7-13 16:48
i'm pretty familiar with the concept of CTD....so no worries with that....BUT when a price for the future is given why applying the conversion factor??? when CTD price is given I would apply...if you like i would also apply when futures price is given and i would physically hedge with CTD in the cash market...作者: PalacioHill 时间: 2011-7-13 16:48
Yes, that was my understandint too: Bond Fut Price=CTD price/con. factor作者: IAmNeil 时间: 2011-7-13 16:48

So, conversion factor is incorporated in futures price ?
