U.S. stocks fell, with the Standard & Poor’s 500 Index extending its steepest weekly drop since March, as Greece scrambled to avoid a cash crunch and energy shares tumbled with the price of oil.

The S&P 500 slipped 0.4 percent to 2,068.79 at 4 p.m. in New York, after earlier erasing a 0.9 percent drop. The gauge lost 1.2 percent last week.
