So much for the rally. U.S. stocks ended flat after a choppy trading session Tuesday, amid a sharp sell-off in Hewlett-Packard shares and renewed worries about Europe.
Investors were already on edge as European finance ministers met to discuss the latest release of bailout funds for Greece. The meeting came a day after Moody's downgraded France's credit rating, bringing worries about Europe's debt crisis back to the forefront.
Then, HP stole the spotlight early with a bombshell announcement: It's taking a $8.8 billion writedown on its purchase of British software firm Autonomy, after the company allegedly misrepresented its finances. Shares of HP(HPQ), part of the Dow 30, dove 12%.
The broader market flip-flopped throughout the day, cooling off after a rally Monday that was staged on investors' increased optimism about lawmakers reaching a deal on the fiscal cliff. But Tuesday's comments from Federal Reserve chairman Ben Bernanke offered little solace, as he urged lawmakers to act quickly because "the stakes are high."
Experts say stocks will remain under pressure and trading will likely be choppy until an actual fiscal cliff deal is finalized, which could take weeks.
Other U.S. news Tuesday was mixed, with some signs of a recovering housing market. The Census Bureau reported Tuesday morning that housing starts rose to the highest level in four years. But housing permits declined slightly to an annual rate of 866,000 last month, less than the 870,000 expected.
