Small and Mid-Cap Stocks Enter Bear Market

Small and mid-cap stocks entered bear market territory during Monday's trading session, defined by a drop of 20 percent or more from their 2011 highs.

The Russell 2,000 and S&P MidCap 400 Index are down about 25 percent and 24 percent, respectively, from their all-time highs reached on April 29, 2011.  Both indices closed at their lowest level since September 2010.  

Other major indices such as the S&P 500 and NASDAQ Composite came within striking distance of reaching bear market mode.

Despite a 634.76-point drop for the Dow , which led the index to fall below the 11,000-mark for the first time since November 2010, the benchmark is down the least since April 29, posting a loss of about 16 percent.
