Last person out, please turn off the lights. Thx.

ll major benchmarks were down more than 1.5 percent. The S&P 500 Index briefly slid 10 percent below its September record close before clawing back just above the threshold. The Nasdaq Composite Index was almost 14 percent below the closing high it reached in August. And the Dow Jones Industrial Average shed more than 500 points, or 2.1 percent, as angst spread across global equity markets
