Wall Street suffered through another volatile session today. The Dow Jones plunged as much as 800 points — the largest EVER one-day point drop — before recovering to close with a loss of three hundred seventy. The selling spree took the Dow below 10,000 points for the first time in four years. Investors have apparently come to the realization that the Bush administration's 700 billion dollar rescue plan is not sufficient to unfreeze the credit markets. Meanwhile, Standard and Poor reports that the US economy is down nearly thirty percent from the October 2007 peak. Fourteen percent of this drop has occurred since September 1st, 2008.
