TSE Announces Trading Session Revision
Regarding the extension of the trading hours of the Tokyo Stock Exchange (TSE), there are comments citing the benefits of increased trading opportunities from the perspective of market user convenience. Meanwhile, there are also opinions that, depending on how trading hours are extended, current market practices, etc. would have to
be greatly altered, thus increasing costs overall and possibly decreasing efficiency. TSE believes that this should be pursued while maintaining an awareness of market users’ opinions and comparing the costs and needs of the market overall. Based on this policy, TSE published a “Discussion Paper regarding the Extension of Trading Hours” on July 26, 2010 to gather a wide variety of opinions from domestic as well as overseas related parties including investors by soliciting public comments until September 10.
Responses to this have revealed requests to consider extending trading hours for both the cash and derivatives markets, since, first and foremost, from the perspective of a securities market, the trading hours of the Japanese market are relatively shorter than those of other countries. As the market operator, from the perspective of increasing
trading opportunities for a wide variety of investor classes, TSE thinks that, in general, we should positively consider extending trading hours.
However, it is currently difficult to extend trading hours in such manners as changing the times for the opening of the morning session or closing of the afternoon session, or establishing a night-hour session separate from the current morning and afternoon sessions, due to the far-reaching and significant effects of such changes.
As such, TSE considers it appropriate to implement some measures with regard to the break (noon recess) between the morning and afternoon sessions. In the current circumstances, there is extremely high demand for trading executions by the “Itayose” method at the closing of the morning session and the opening of the afternoon session, and also basket transactions during the period of the noon recess. In light of this demand, TSE will not completely abolish the noon recess, but will extend trading hours by shortening the noon recess while maintaining the framework of current operations to a certain extent.
Specifically, in consideration of the balance between the trading hours of the morning and afternoon sessions for the auction market for cash products, in order to enable trading in response to moves in other Asian markets, TSE will make necessary revisions, such as changing the closing of the morning session from the current 11:00 am to
11:30 am. TSE will also make necessary revisions with regard to the derivatives market, such as changing the closing of the morning session for index futures and options trading to coincide with that of cash products at 11:30 am, and also changing the opening of the afternoon session from the current 12:30 pm to 11:45 am, in consideration of the fact that other Japanese equity index futures contracts are already being traded during the period of the noon recess in Japan.
Furthermore, TSE will continue to examine ways to extend trading hours, while paying sufficient attention to the needs, cost for adaptation, market practices, etc. of market users, so as to contribute to increasing convenience for market users.
With regard to the trading hours for the auction market for cash products (excluding those which do not have morning sessions), the morning session will be 9:00 am –11:30 am.
