The S&P 500 finished the day down 12.14 points, or 0.89 percent, at 1350.52. That was well off its session low of 1337.56, reached shortly after the open.
The Nasdaq 100 settled at 2589.93, a loss of 28.11 points, or 1.07 percent, after rebounding from its low of 2549.96. Much of index's resurgence can be attributed to strength in shares of Google and Apple, which saw early selling but were met with convicted buying into the close.
The Russell 2000 shed 12.64 points, or 1.6 percent, to close under Friday's support level of 790 at 778.90.
