Even as Barack Obama signed the so-called stimulus bill into law and is readying another $50 billion in spending to fend-off forclosures, the markets closed down significantly today.

The Dow Jones Industrial Average shedded 297.96 points or 3.80% to close at 7,552.45. The index came within a point today of reaching a 5 year+ low that was met last fall.

The NASDAQ actually faired worse, ditching 63.7 points or 4.15% to close at 1,470.66.

The S&P 500 lost the most as far as percentages go, falling 37.67 points or about 4.56% of its value. The index closed at 789.17. That’s down significantly from a 52-week high of 1,440.24 points.

If everyone agrees that this stimulus package was the right choice and it will stimulate the economy, why do investors continue to ditch shares? Why are we still falling, having lost about 2,000 points on the Dow since November 5th? Why, even with another $50 billion for homeowner protection and $350 billion in TARP coming down the pike, are we still getting several hundred point drops by the day?
