(REUTERS) -- Stocks fell on Monday after Greece's efforts to reach a debt restructuring with creditors stalled, hampering European leaders' push to shift the market's focus to jobs and growth.

Negotiations between the Greek government and private bondholders over the restructuring of 200 billion euros of debt made progress over the weekend, but a final agreement could not be reached before the start of a summit of European leaders.

They've been saying they're on the verge of a deal for a long time.

The European summit initially was to focus on ways to revive growth and create jobs in a climate of fiscal austerity.

The Dow Jones industrial average dropped 67.62 points, or 0.53 percent, to 12,592.84. The S&P 500 index lost 7.86 points, or 0.60 percent, to 1,308.47. The Nasdaq Composite fell 8.94 points, or 0.32 percent, to 2,807.61.

The major indexes were earlier down more than 1 percent.

Despite Monday's decline, some traders stressed the resilience of U.S. stocks. Even though the euro zone crisis drags on, the S&P 500 was on track for its best month since October, helped by stronger U.S. economic data.

Apple shares helped cap losses on the Nasdaq after Morgan Stanley said the iPhone maker could add China Telecom <0728.HK> and China Mobile <0941.HK> as distributors over the next year. Apple rose 1.3 percent to $453.02.

Consumer spending, the main pillar of the U.S. economy, was flat in December as households added to savings after the largest rise in income in nine months. Although the data pointed to a slow start for spending in 2012, economists were cautiously optimistic that an improving labor market will support demand.
