S&P at 12-year low, Citi stirs fear

NEW YORK (Reuters) - Stocks fell and the S&P 500 closed at a 12-year low on Friday, after the government said it will take a large stake in Citigroup's common shares, fanning fears it will increase its role in other major banks.

* Healthcare and drug companies, such as Merck & Co and Johnson & Johnson Inc , fell for a second day on worries that U.S. President Barack Obama's budget proposal will strangle profits as the administration tries to rein in healthcare costs.
