donyoshi - i am with you - i am bearish on CB "arb" funds. the actual value, in the sense of assets being cheap by any reasonable arbirtage-type measure, is pretty much zero in the asset class.you might look at a graph of implied vol and say "gee it is low compared to historical, so it will have to go up". but even if it does, index options will probably outperform CBs on the way up as CB arb guys try to "lighten up" their positions (meaning sell them to other CB arb guys).i think being short CBs over the next 6-9 months could be profitable as redemptions in CB funds cause CB positions to be more and more highly concentrated with fewer funds, and the leverage in the system increases. any situation in which you find a group of leveraged guys on one side of a trade, and long term money on the other side, will lead to instability eventually.the CB "arb" phenomenon is definitely a bubble, with 2003 being the golden year. CB "arb" funds played the various carry games that year. all you needed was to be long the CB and short stock with no rate hedge. then you got the carry trade due to the upward sloping yield curve, the carry trade due to taking unhedged credit risk (this is arbitrage??) and as long as the markets stay reasonably volatile the vol part of the equation should be ok. i couldn't believe people didn't see what had happened that year - and a flood of money poured into the sector in 2004. amazing.
