Stocks fell Thursday, losing early gains as investors examined President Barack Obama's budget request and remained cautious about the outlook for the U.S. economy and banking sector. Stocks rose in the morning along with gains in the banking sector, but the advance lost momentum around midday and shares fell significantly in the last hour of trading. Obama outlined his federal budget plans for the next ten years, with a more detailed account due in April. The $3.55 trillion plan includes making permanent some tax breaks from the economic stimulus plan, ending certain tax breaks for the wealthy, and moving closer to a universal health-care system. The budget includes an additional $250 billion to stabilize the financial system, which Obama's economic advisors say would be the net cost of buying up to three times as much in bad assets. That would be in addition to the $700 billion bank rescue plan already in existence.
