Since April 2020 HSBC FTSE All World Index accumulation fund is reporting an OCF 0.13%…
It is equivalent to VLS100 rather than VLS80.
You could make it VLS80 with no fee to pay by put aside 20% into high interest Regular Saving Account (RSA), High Interest Current account. In the UK for instance, you could still get RSA for 2% a few are even paying 3%. The intest rate might be increasing with the bank start increasing their interst rate. About 3-4 years ago you could get RSA, High Interest current accounts paying 5% interest. Alternatively if you are fancy to pay OCF 0.15% Vanguard Global Bond Index Fund.
The advantage of put aside 20% into high interest Regular Saving Account (RSA), High Interest Current account; it is easily accessible. You will have to do this anyway for emergency cash.
I am investing in VLS100 but seriously considering to move it to S&P500, FTSE 250, Russell2000 (if available) and do the rest with self-composed actively traded portfolio to comprise high growth stock emerging market, penny stocks with potential runners and multi baggers.
S&P 500 is arguably is still global portfolio as the companies within S&P are global companies with international exposure and revenues comes from multiples countries. I have done self composed portfolio since lat year and will keep adding more in the future.
