Dow Sinks 300-Plus at Open

It could be yet another long day for the markets. The Dow sank more than 300 points at the open this morning, with China again taking the brunt of the blame. The early swoon comes a day after US stocks closed out their worst month in more than three years. The Dow Jones industrial average fell 335 points, or 2%, to 16,200 in the opening minutes of trading. The S&P 500 fell 37 points, or 1.9%, to 1,935, and the Nasdaq slid 82 points, or 1.7%, to 4,695. The signs of weakness in China, a major importer of oil, sent the price of crude skidding 4%. (More stock market stories.)
