NEW YORK (AP) — The latest on the global financial market turmoil (all times local):
At its peak Tuesday, the Dow was up 441 points from its previous day's close. After a sharp sell-off in the final hour of trading, the index ended the day down more than 200 points. In all, it was a swing of more than 660 points.
The S&P 500 closed down for a sixth straight day and is off 12 percent from its record close of 2,130.82 on May 21.
Strategists said that there was no obvious catalyst for the late sell-off, suggesting that investor confidence is still fragile after a series of big sell-offs.
As well as concerns about the outlook for growth in China, investors are also getting jittery about the prospect of a potential rate increase from the Federal Reserve this year, said Scott Wren, a senior global equity strategist at the Wells Fargo Investment Institute.
"You're going to be in a volatile period here for some amount of time," said Wren. "It feels like it's going to take a little while to work through. ... Typically, it takes some time to really find the bottom (in the market)."

China's interest rate cuts will not be enough to ease concerns about the country's economy, says Kamel Mellahi, professor at Warwick Business School in Britain.
"The Chinese economy is going to be on this bumpy road for a while and it will have ebbs and flows that will no doubt have a serious impact on the global economy," he says.
The Chinese central bank cut its key interest rate and deposit rate on Tuesday after its main stock market plunged for a fourth day. The move boosted markets around the world.
Mellahi says that while the rate cuts may buoy markets in the short-term, the underlying causes of investors' concerns — the slowdown in the Chinese economy — will last for some time.
