The Tokyo Stock Exchange will consider ways to extend stock trading hours to strengthen its international competitiveness with rival exchanges.
The options to be discussed include eliminating or shortening the lunch break, introducing after-hours trading for cash stocks, starting morning sessions earlier and expanding after-hours trading for derivatives.
The ideas of extending trading hours was repeatedly rejected in the past due to concerns about costs of upgrading systems and hiring more staff. The debate was rekindled as Osaka Securities Exchange recently said it would eliminate lunch breaks for derivatives trading in Q1 2011.
