(New York)

Jack Bogle, the founder of Vanguard, is a legendary name is investing. Not only did he found and grow one of the largest asset managers in the world, but he has a habit of being right when he predicts returns. Well, he has just made another prediction, and unfortunately it is not one investors will like. He thinks returns over the next decade are going to lag their historical levels badly. His forecast is that investors can expect a 1.75% net return with a 50%/50% stock-bond portfolio over the next decade.

FINSUM: If this call turns out to be right, it will have huge implications for retirees and pension funds, as “safe spending” rules and total returns for pensions will be devastated. That sad, we think forecasting that far out is all but useless.
