Hi guys, I'm considering buying US shares for diversification and would very much appreciate your advice on the best way to do this. I've never bought US shares before thus the experience is very limited. Let's say I'd like to invest approx. $40k AUD. I'm currently with cba and they seem to be able to do this via commsec. I'm not sure about the exchange rate they apply though and whether there are any better options in terms of commisions charged, exchange rates, etc. Also, I'm considering whether to invest cash saved or create a $40k split for my PPOR home loan, repay it and reborrow to invest in shares. If I understand it correctly the interest on the borrowed money would then be tax deductible in such case. Is it worth doing so?
