It would be great if someone here could tell you exactly the right funds and percentage allocation for your investment to ensure you get the very best returns but I don't think anyone can provide you with that unfortunately. Everyone has different opinions and no one can predict the future.
Speaking personally however, I feel it's a little strange to completely ignore the Irish market. I recall the prophets of doom pontificating about the coming property crash and its calamitous effects on the Irish economy and stock market at the time of the SSIA launch. I was influenced by their arguments and avoided Quinn Life Celtic Freeway which I had been considering. As a result my SSIA is worth a lot less than it might have been. Now, maybe they'll be right this time around but who knows? The Irish economy has a knack of confounding the sceptics against all the odds and it seems at least worth including it in such an investment mix. Also, remember you'll be paying 1.5% on China and Japan and 1.2% on UK in management charges whereas it's 1.0% on Celtic Freeway. And as mentioned by dublinman you have currency risk to think about, that won't arise with Celtic Freeway.
Just some things to think about. I'm sure there will be others who feel you're right to steer clear but that's just my reaction upon looking at your prospective allocation.
