This seems like a huge discrepancy to me, and while the professional prognosticators always qualify with a time period (usually 10 years), many individual forum posters do not.
- when people around here quote low (2% real) future returns, what time period is that usually attached to?
- has there ever been a wider range of typically expected returns? (Assuming 2-8% over 10 years)
- while I see many quoting historically low returns over the next ten years, would these same people be more comfortable quoting a closer-to-historical number for a longer time horizon, like 20 years?
