Following a tumultuous, volatility-filled ride, stocks over the past 11 months are about right back where they started. Many investors, though, haven't been so lucky.

The market last closed at its current level on Oct. 6, three weeks after the implosion of Lehman Brothers and the ensuing collapse of the nation's financial system. Stocks hit intermediate lows in November and then again in March, followed by a resounding rally that, by rights, should have many investors back on their feet again.
