That is a historical fact and history is the best (really the only true) guideline for equity behavior that we have. Anything beyond is conjecture.
This is a seriously dangerous notion. Permanent loss (or rather loss over a human lifetime) is possible, otherwise equities are riskless. What we know from past performance is the average return and standard deviation of returns. We can’t expect the 146 years of historical data on US equities to represent the full range of outcomes for US equity returns, so we have no basis for concluding that permanent impairment is impossible.
Please tell me of one documented instance of “permanent loss in an appropriately diversified equity portfolio” – I’m all ears.
Because something hasn't happened in the last 146 years, basically two human lifetimes, it can't ever happen in a human lifetime?
