The document discusses various strategies for managing wealth over long periods of time. It shows how the range of outcomes can widen over decades for investments. Different investment allocations and strategies are compared over a 90-year period, showing returns, risk levels, and ending wealth amounts. The optimal strategies combined stocks and bonds, diversified globally, and rebalanced periodically to control risk. They illustrate how working with a wealth manager can produce better long-term outcomes than going it alone.
