Exchanges: Plus adds to its services

Plus Markets, a London exchange group, has launched a new trading platform and expanded the list of stocks it trades. The new system, provided by OMX, will offer cheap quote-driven trading in 7,500 securities including the stocks of all the companies listed on the London Stock Exchange, 70 AIM-listed companies and several of the most liquid continental stocks. This is in addition to the more than 200 stocks listed on Plus itself. The move has come as a surprise to some market observers, who thought that Plus’s ambitions were confined to small-cap and micro-cap stocks and who believed that Plus was positioning itself as an alternative to AIM.
