  • Certainly it has been a rough year for the markets. Exactly one year ago today, the Dow Industrials and S&P 500 both closed at record highs. Since that day, the Dow has plummeted nearly 5,000 points, and the S&P has dropped a more impressive 600 points.

  • Starting the week off on a sour note is nothing new for the markets. Falling over 500 points today, the Dow continues a trend it started three months ago. Since July, the Dow has posted gains on only 2 of the last 13 Mondays.

  • After taking into account Monday’s plunge, the Dow Industrials is now down 27% from its October 2007 high. The S&P 500 and the Nasdaq Composite have fared a bit worse, declining 29% and 31% from their respective highs last October. Take a look at how some of the other major U.S. indices and sectors have performed since their 52-week high (including Monday’s fall)It's been a rough twelve months.  The Dow and S&P are looking to have their 4th straight quarter of declines, something not seen in years.  Here is a preview of the quarter end stats and the winners and losers to date.

  • While Kraft Foods will be joining the Dow Industrials on Monday, in a way, it's not the first time it has been a part of the Dow.

  • Despite all of the developments this week, with a current market cap of $5.5 billion, AIG remains bigger than just over a quarter of its fellow S&P 500 components.

  • Falling oil prices continue to put pressure on energy stocks. Now at a six-month low, the S&P 500 Energy sector is down nearly 19% this quarter, by far the worst-performing sector in the S&P 500 since July 1.  With the decline today, the energy sector’s weighting in the S&P 500 is now less than the weighting of the healthcare sector.

  • This past Saturday marked the one-year anniversary of the Dow Industrials’ first close above 14,000. Needless to say, it has been quite a ride for the Dow since it first reached that milestone; the Dow continued to establish new all-time highs into October before falling to 2-year lows this month.

  • Financial stocks continue to deteriorate this week with lingering concerns over Freddie Mac & Fannie Mae and continued weakness in regional banks following the collapse of IndyMac Bancorp.

  • The bears are out on Wall Street now, as the Dow Industrials and Nasdaq Composite officially closed in bear market territory (down 20% from highs) today.
