DJIA extends slide, erases more than 2,000 points

• Wall Street's main indexes fail to stage a meaningful rebound.
• Energy and financial shares continue to suffer substantial losses.

Major equity indexes started the day deep in the negative territory and trading was halted for 15 minutes as the S&P 500 registered a 7% drop right after the opening bell. Although Wall Street's three main indexes were able to retrace a small portion of the early losses, they came under renewed bearish pressure and fell below their opening lows.
