Stocks are opening mixed after European leaders failed to agree on releasing more financial aid to Greece.

In order to get the aid, Greece has to agree to more budget cuts, which has been causing unrest and political upheaval there. The Greek government faces a confidence vote on Tuesday.

If Greece defaults on its debt, it could trigger losses for the banks that hold Greek bonds, and economists worry it could shake the European economy and roil financial markets.

The S&P 500 is down a point in early morning trading at 1,270. The Dow Jones industrial average is also down less than a point at 12,001. The Nasdaq composite index is flat at 2,617.
