Those who follow equity markets closely will be under no illusions about where the place to be has been in recent years. The US equity market has handily trounced all-comers. For US domestic investors who often have little overseas exposure, this has been great news. However, it has also been good for non-US investors who adopt a global approach to investing. The US makes up a huge part of the investing universe for global mandates and hence non-US investors have benefitted significantly.
