Dow Loses Gains Following Morning Surge

The Dow closed lower again, following another roller coaster day.

— -- A day after U.S. stocks had their worst day in four years, the major stock indices closed lower after a surge in the morning.

By this afternoon, the indices had lost most of their gains. The Dow closed the day lower, about 1.3 percent, while the S&P 500 closed 1.4 percent lower. The Nasdaq closed lower 0.4 percent.

"The markets are caught between a domestic U.S. economy that is still struggling to gain momentum, but remains firmly in positive territory, and a global economy that appears to be poised for ongoing weakness," Lindsey Piegza, Stifel chief economist, said.

The Shanghai Composite Index was down 7.6 percent earlier today, leading to its biggest four-day fall since 1996. Shares there continued their downfall despite a move today by The People’s Bank of China to cut lending rates with the hope that banks lend more money. The Chinese central bank cut interest rates for the fifth time since November to 4.6 percent from 4.85 percent and it lowered banks' reserve requirement.

Mark Zandi, chief economist with Moody's Analytics, said the move by the Chinese government has given a lift to global stock markets, while U.S. economic data released this morning, including new home sales, showed strengthening.

"Most importantly, consumer confidence looks solid, particularly consumers' assessment of the job market," Zandi said, referring to the index of consumer confidence in August released today. "While the stock market is swinging up and down, the economy continues to steadily power forward."
