Done a search on index funds. Looking at my options deciding between STW and IOZ. I hear a lot supporting STW on these forums and not much talk of IOZ. IOZ offers lower expense ratio (0.19 vs 0.29) but still seems to be the less favourable option? is there more difference to them than just this? Also - is the ASX MSCI 200 index different to the ASX S&P200 index?
