Stocks faded in the final hour of trading Tuesday to finish lower following news that Greek depositors withdrew 700 million euros from the nation's banking system and after Greece's leaders failed to agree on a coalition government.

The S&P 500 closed at 3-month lows, while the Dow logged its ninth loss in the last 10 sessions. Major averages are on pace for their biggest monthly losses since last September.

According to a transcript, Greek depositors recently withdrew 700 million eurosfrom the nation's local banks, said President Karolos Papoulias, though the exact timing of the transfer was unclear.

"I think people need to prepare for the eventual removal of Greece from the EU and investors are getting ahead of that before they're forced to," said Matthew McCormick, vice president and portfolio manager at Bahl & Gaynor Investment Counsel on CNBC's "Closing Bell." "It's a political market and an event-driven market."
