On 6th December 2010 NASDAQ OMX Copenhagen will launch a few changes in the
calculation of average prices and yields etc.
At present two average price concepts are published, i.e. the average price,
which is a turnover weighted average of on-exchange trades of type standard,
and the all-trades average price, which besides the on-exchange trades also
includes OTC-trades of type standard published via NASDAQ OMX OTC publication
service.
NASDAQ OMX Copenhagen has in cooperation with members and issuers decided to
only calculate and publish the all-trades average price.
As a consequence the price basis for calculation of yield and duration etc.
will be changed. As of 6th December 2010 these calculations will be based on
primarily the all-trades average price and alternatively the best bid price at
closing (if no trade has taken place that day).
NASDAQ OMX web will also be changed as the average price will be left out. The
same applies to the Official Pricelist where the all-trades average price will
replace the current average price. Equivalently the average price will be
removed from the Genium Consolidated Feed. For further information on this
please see the coming weekly newsletter from NASDAQ OMX Global Data Products.
For more information about average prices etc. please see the attached coming
version of Guidelines for the publication of real-time trading information and
calculation of prices, etc. for bonds, NASDAQ OMX Copenhagen, which will come
into force on 6th December 2010.
