Stocks finished near session lows Friday, breaking a three-day winning streak, sparked by fresh fears over the euro zone sovereign debt crisis and after a batch of mixed earnings reports.
The Dow and Nasdaq slid back into negative territory for the month, but all three major averages still posted modest gains for the week.
The Dow Jones Industrial Average tumbled 120.79 points, or 0.93 percent, to close at 12,822.57, led by H-P and BofA .
The S&P 500 fell 13.85 points, or 1.01 percent, to end at 1,362.66. The Nasdaq dropped 40.60 points, or 1.37 percent, to finish at 2,925.30.
The CBOE Volatility Index, widely considered the best gauge of fear in the market, ended above 16.
For the week, the Dow gained 0.36 percent, the S&P 500 rose 0.43 percent, and the Nasdaq added 0.58 percent. Pfizer was the best performer on the-chip index for the week, while BofA led the laggards.
