I have a HKD callable bond maturing in 2022. the call schedule is bermudan and the next call date is 10/17/16 and redemption price is 100 (the call date is 10/17 every year till maturity). Initially it was priced to next call date using a comparable that was maturing around previous call date 10/17/15. The yield was around 1.1% based on comparables. If I look at the history, a year prior to now it started at a price of 104 and slowly converged to call price and now it again jumps back to 104.
My question is - is this correct? i.e. is pricing to next call and jumps around call date justified? I don't have a comparable bond maturing in 2022, but do have a few maturing around the next call date.
