"The perception that investors are 'forced' to hold stocks is driven by a growing inattention to risk. But Investors are not simply choosing between a 3.2% prospective 10-year return in stocks versus a zero return on cash. They are also choosing between an exposure to 30-50% interim losses in stocks versus an exposure to zero loss in cash. They aren’t focused on the 'risk' aspect of the tradeoff, either because they assume that downside risk has been eliminated, or because they believe that they will somehow be able to exit stocks before the tens of millions of other investors who hold an identical expectation that they can do so."
