Hi Sandy,
Drops like that would normally be associated with a big widening of credit spreads due to an external market shock, i.e. the markets pricing of default risk. That wasn’t the case. Interest rates going higher are not a new thing for the market, and while they are a negative for fixed rate bonds , I doubt that would be the reason. The NTA on the fund sits around $1.96/97 and hasn’t changed much. It’s worthwhile keeping an eye on the daily NTA which is released to the ASX . I suspect someone has traded a reasonable parcel and not used a limit order, which has caused a spike lower in the price. NB. MM used to own NBI in the Income Portfolio however we sold out some time ago.
