Doubt it matters as share prices and earnings are in each respective currency — £ for FTSE and $ for S&P

That said its hovered between £1:$1.2 and £1:$1.4 for the past few years

Well arguably if I invest in US market, it is with USD. The full return of investing in other markets should be then taking into account the currency's convesion, no?

For example, if I get a 10% in the US market, and a 15% in the UK market, But GBP goes from 1.2 to 1.4 in the same period, then I am actually losing on my investment?

1 USD => 1.2 GBP => 1.61 GPB => 0.985714 USD

Yes, fair

I have assets in both sterling and usd and tend to allocate in each region rather than exchange one for the other

Its part of my longer term hedge against the US

It's a good article and I think the points it makes are (very) valid... but I also think that as long as the USD is the dominant currency that the rest of the world "wants" to transact with, the US markets are going to benefit from it.

"USD is our currency, but it's your problem" has never been more true IMO!
