TOKYO, March 4 (Reuters) - Trade in Nikkei futures, options
and some derivative products was suspended on the Osaka
Securities Exchange on Monday due to technical problems, Japan
Exchange Group said.
"We don't know what time they will resume trade yet. We are
checking details now," an exchange spokeswoman said.
Cash trading of the benchmark Nikkei 225 index on
the Tokyo Stock Exchange has not been affected.
The Nikkei volatility index was down 25.8 percent
before the suspension. The lower the volatility, the higher
investors' risk appetite.
