More than half the respondents to a separate survey by shareowner activist and former exchange director David Webb said they favored a one-hour break. Instead, the exchange’s board approved a switch to 90 minutes from March 7, and to one hour in March 2012, so people can get used to it. Open up a little earlier, the trading day will be extended to 5 hours and 30 minutes by 2012 from 4 hours current.
The main exchanges in the U.S., U.K., Australia and Germany operate for 11 hours a day, without a break. This looks like one area where China appears willing to lag behind.
