Also, mortgages have a duration (a calculation of the time it takes to get paid back) that is a variable, hypothetical duration that varies with prepayment speeds, so a short duration mortgage portfolio is not protection against a sudden increase in interest rates, because if interest rates rise the duration will rise which hurts the value of the bond.
