NEW YORK (Reuters) - U.S. stocks fell on Tuesday as a credit downgrade of France by ratings agency Moody's and a huge accounting charge by Hewlett-Packard gave investors reasons to pull money off the table after a two-day rally.
Hewlett-Packard Co (HPQ.N) tumbled 11.8 percent to $11.73 as the computer and printer maker swung to a fourth-quarter loss. The company said it took an $8.8 billion charge related to its acquisition of software firm Autonomy, citing "serious accounting improprieties.

Moody's Investors Service cut France's sovereign rating by one notch to Aa1 after the market's close on Monday, citing an uncertain fiscal outlook as a result of the weakening economy.

"Because the delta of outcomes is so gigantic - you could have us go off the fiscal cliff, Europe blow up or fiscal cliff gets passed, growth resumes, Europe grows its way out of the debt crisis - we are just waiting for direction and the fiscal cliff is that first piece of information."
A bright spot for the economy came in data showing U.S. housing starts rose to their highest rate in more than four years in October, suggesting the housing market recovery was gaining steam.
