I have some money to invest. I already have holdings in LICs, but I am a bit overwhelmed by the variety of choice in ETFs. Some ones which stick out for me are ASX 200, S&P 500, S&P Asia 50 and the S&P Global 100. I have no idea which to buy. Assuming purchasing multiple is best, I have no idea how to weight my allocations (i.e. 20% to this, 40% to that, etc.) Any advice?
