The Dow Jones industrial average closed in correction territory Friday amid global growth concerns and continued selling in the oil market.
With a drop of 530 points, the blue chip index was more than 10 percent below its 52-week high (also an all-time intraday high) of 18,351.36. The index reached the mark May 19.
It was the first full 10 percent correction for the Dow since 2011. The battering brought the Dow down 1,017 points this week, its worst week since September 2011.
The drop marked the first loss of more than 500 points since August 2011. The index has only shed that much three times in the past five years.
Apple has spiraled down more than 18 percent since May 20. At its close Friday, the stock was down more than 21 percent from its 52-week high on April 28.
