Stocks fell on Monday as concerns over Greece's teetering finances returned to the forefront, extending losses from the previous week.
Concerns over Europe's sovereign debt problems contributed to Wall Street's worst quarter since the depths of the financial crisis in 2008.
Greece will miss its deficit targets for both this year and next despite harsh new austerity measures, draft budget figures showed, and could be forced to seek more bailout funds.
The draft budget brought the prospect of a Greece default closer and will weigh as euro zone finance ministers meet to discuss the next steps toward resolving the currency area's sovereign debt crisis.
I don't think Greece will be allowed to default, but concerns about the situation in Europe are causing us to pull back now as there's still so much uncertainty about what could happen, said Dave Hinnenkamp, chief executive officer of KDV Wealth Management in Minneapolis.
It's pretty hard to be optimistic right now.
