The factory output in Japan jumped back after facing a decline in June, but still the investors are concerned about the slow growth of the economy, which was showcased in the poor performance of Nikkei 225 Stock Average for the first time in four days.

In July, the factory output in Tokyo surged 0.3% from the June’s decrease of 1.1%. The retail sales that declined significantly in five years in May also increased for a second month, as adjusted seasonally.

In anticipation of the freezing of the global recovery blended with the worry of a very slow growth in the personal incomes in the U.S., the Nikkei 225 Stock Average declined 2.6% to 8,912.33 in the morning session, which happened for the first time in four days.

As believed by some analysts, the stimulus package of 920 billion yen announced by the Bank of Japan and Prime Minister Naoto Kan on August 30 won’t suffice the need of the economy.

The report released by Labor Ministry revealed that the retail sales climbed up 3.9% and the wages increased 1.3% as compared to last year.

Norio Miyagawa, Senior Economist at Mizuho Securities Research and Consulting Co. in Tokyo, said, “Even if we see better-than-expected Japanese economic data, stock and currency markets are focusing on the U.S. and China”.
