It’s not rocket science. If you invest in the US and the A$ falls 10 per cent against the greenback, you’ll receive an extra 10 per cent return when you eventually bring your money home. The same can also be said for those investing locally in stocks that derive a good chunk of their income from foreign earnings.
Established healthcare businesses, many of which have substantial operations outside Australia, like CSL Ltd, and consumer discretionary stocks benefit from a weaker Aussie dollar, due partly to segmented pricing which makes local retailers more competitive relative to overseas online stores.
As a rule of thumb, a 10 per cent drop in the A$ adds around 3 per cent to corporate earnings.
To determine the A$ impact on earnings, find out the percentage of profits generated from the company’s international operations and apply the change in currency to this proportion of profits.
