U.S. stocks fell today as investors grew increasingly worried that government efforts may not be enough to revive a recession-weary economy and steady the banking system, Reuters reported. Although Congress prepared to pass a $789 billion economic stimulus package as early as Thursday, uncertainty about the economy fueled a broad-based sell-off. JPMorgan, down 4.4 percent, was among the top drags on the Dow Jones industrials, while 3M fell 3.6 percent. "Nobody has confidence in the plan at all," said Tim Ghriskey, Chief investment officer of Solaris Asset Management in Bedford Hills, New York. "All of us are looking for action and details and I think that lack of visibility, that lack of transparency, is critical here. That is overhanging the markets.", he added. The Dow Jones industrial average dropped 223.25 points, or 2.81 percent, to 7,716.28. The Standard & Poor's 500 Index fell 23.36 points, or 2.80 percent, to 810.38. The Nasdaq Composite Index shed 30.14 points, or 1.97 percent, to 1,500.36.
