These numbers from Alicia Munnell, economist at Boston College, are unbelievable.

The stock market, as measured by the broad-based Wilshire 5000, declined by 42 percent between its peak in October 9, 2007 and October 9, 2008. Over that one-year period, the value of equities in pension plans and household portfolios fell by $7.4 trillion. Of that $7.4 trillion decline, $2.0 trillion occurred in 401(k)s and Individual Retirement Accounts (IRAs), $1.9 trillion in public and private defined benefit plans, and $3.6 trillion in household non-pension assets.
