The Designated Sponsors in Neuer Markt performed especially well: 335 of the 342 companies in this segment have at least one Designated Sponsor with an AA rating. In the Nemax 50, with one exception, every company has at least two Designated Sponsors with the highest performance rating.
The first letter of the rating stands for the quotation time. Sponsors who enter quotes for more than nine and a half hours a day are rated "A". Sponsors who enter quotes for less than one hour a day, on the other hand, are rated "D". The second letter of the rating stands for the difference between the bid and ask price, the so-called spread. Sponsors who have quoted prices that, as a whole, are at least one fourth narrower than the maximum permissible spread are rated "A". If a Designated Sponsor fails to meet the minimum criteria in 10 percent of the equities for which it is a sponsor, it drops out of the rating with all of its designated stocks.
