World stock markets plunged after China's stocks fell nearly 9%, but US stocks recovered some losses in volatile trading. European markets closed down over 5% following steep declines in Asia. While the Dow dropped over 1,000 points at the open, it eased to a loss of under 2% by afternoon as US traders focused on domestic economic strengths. Commodity prices like oil also rebounded slightly after early steep falls due to concerns over weaker Chinese demand, but volatility was expected to continue given recent sharp market moves.
