Sorry, I meant the vsaagg Ticker that you pointed to earlier. That is a fund and not an etf.
Maybe a typo earlier. The four I'm on now are all iShares Irish domiciled LSE listed ETFs:
Just wanted to add one more to this list of passive ETFs.
iShares US - AOA (The last A stands for Aggressive, as in it has a 80/20 stocks & bonds mix - other allocation mixes are available if you want and look at the iShares Core Multi Asset funds in the US)
Liquidity and spreads for AOA are not optimal and this one is subject to 30% withholding tax, but if you're restricted to US / HK options, this is certainly an option to consider for long term buy/hold as a single ETF.
