1. The MSCI World index is their benchmark. They do not just invest in it, because their stock selections (even after fees) usually beat the index.
2. Just looked at my 3Q22 report. China comprises 2.66% of my portfolio. ymmv
3. They will take some counter positions, so if their forecasts of general directs are wrong, they have some investments that dampen the effect. Even with that, (even after fees) they usually beat the index.
4. Their lower volatility means they usually beat the index in up markets, and they usually drop less than the index in down markets.
5. That beats not only the indexes, but beats 98% of the managed funds.
No, I get no compensation from them. Just a client who is satisfied with their performance over time.
