Markets Brace for a Possible Lost Decade as Bubble-Era Valuations Return

Valuations are stretched, nearing levels seen at the March 2000 burst, and Hulbert cites a CAPE-based model that once forecast a negative real-return decade (S&P 500 about -7% annually, Nasdaq-100 about -10%). With today’s high valuations and AI hype, the coming decade could deliver subpar gains despite a prolonged bull run, reminding investors that 'this time is different' arguments often precede a disappointing stretch.
