Washington talks and investors walk. Stocks put in their longest losing streak in three months as a solution to the fiscal cliff continues to elude Congress and the President. With a Monday deadline looming trading was volatile on rumors the President would offer a new budget plan. That turned out not to be the case and the major benchmark indexes slid in late day trading, capping their fifth straight day of losses. The Dow and the Nasdaq both lost ground during the holiday-shortened week.
