Hi Anzania, before I shoot off from the office, I thought I’d elaborate.
I'm not all that concerned with volatility over the long term (50 years is a long time after all).
They're going into the kids trusts accounts anyway so I'm looking for yield not capital price movements. The bonds have quite good duration and will pay themselves off by the time the kids get anywhere near their accounts. Besides, everything is a risk free asset after 19 years!
I have an extensive portfolio of bonds and I’m not all that happy with the low level of implied risk. I thought that these might be a way of increasing it slightly.
In addition to that, I try and spread my portfolio of direct and indirect investments over the globe. I have some small business interests in Italy as well, so it all gels nicely together.
Are you an investor yourself?
Ms Robinson.... Lachlan is spoken for, but I’m sure you are quite charming, thanks anyway
