Humans can be faulted for behaviors of all sorts, and our penchants when investing are not immune to such criticism. One of the more powerful biases is our tendency to see the recent past as a fuller record than it is. As went the past few years, so must have been the past few decades, no? Not invariably, perhaps not even often so. The outperformance of the U.S. equity market seems to have many regretting international stock exposure. We find such thinking faulty both for the potential additional diversification a global portfolio presents, as well as what we may expect to prove more rewarding potential longer-term return.
