I encourage and implore TAT investments to take advantage of people's greed and sell into the bid to 0.001/unit. Bidding over face value for a recallable face value bond is probably unwise. There are other places to put your money -- notably Graet.Loan and even Ukyo.Loan which pays 50% more than XBOND. Both of those haven't sold out their IPO yet so I don't understand why there is such a demand for XBOND.
I would think it obvious... many people have purchased these bonds in order to have the first crack at future TAT IPO's. The daily interest may turn out to be a small part of the overall return should those IPO's behave like recent issues on Havelock and BTCT.
