The blue-chip index fell by nearly 700 points during its intraday trading and it eventually lost 476.09 points, or 4.7 percent. It closed at 9,648.43 points.
"All the bad things are coming together," said Robert Halver, head of the capital market analysis department of Baader Bank, citing the strong euro, the slowdown of the emerging economies, the discussion about the interest rate hikes in the United States. They are enough to bring the DAX down in the weak summer season, he added.
However, Halver is optimistic that the DAX index will recover and get higher by the end of the year. Since the interest rates are still low and equities are still a good investment tool.
