In Asia, the stock markets opened Tuesday Tuesday after the Wall Street crisis the day before.
The Nikkei index in Tokyo began to fall 3.5 percent shortly after opening. In Hong Kong, the Hang Seng Index fell by 2.1 percent.
Stock exchanges in Shanghai and Shenzhen, which are less likely to follow other markets in the world, have also fallen, though not so much. The first of them dropped by 1.2 percent, and the fall in Shenzhen by 1.1 percent.
The main index on one of the leading Asian stock exchanges fell from Tuesday. Investors in Asia seem to be wary after they collapsed on Wall Street on Monday due to turmoil over demand in the technology sector.
On the New York Stock Exchange the Dow Jones index fell by 2.3 percent. On Monday, while the S & P500 index in a wider range fell by 2 percent.
The technology-rich Nasdaq stock dropped even more on the day when Apple dropped by 5 percent, while Amazon dropped by 4.4 percent. The main index ended by 2.8 percent less when Nasdaq closed Monday.
