14 JULY 1984, Page 20

Trumpets ppp

Come bulls, come bears to the Stock Exchange, which on Thursday next at five o'clock throws open its doors and in- vites the world to enter. We are welcomed onto the trading floor, which will mount a full complement of brokers and jobbers an endangered species, as the Exchange points out, making a note to ask David Bellamy along. All will be as on a normal business day. Just the chance to act out a

long-nourished dream of raiding War Loan or cornering Polly Peck — or simply to see the Exchange and meet its denizens at first hand. These open days (another follows on 24 July) are the Stock Exchange's part in the City of London Festival, which for the next two weeks brings a positive polyphony of music to the City's churches and halls. Famous city names — banks, insurers, oil companies and others — appear demurely as sponsors. Which, though, will follow the Stock Exchange's example and open their doors to tell their own own story? The Baltic Exchange, the international shipping market, houses two concerts in its marble halls, and insurance brokers Willis Faber do the same in their place at 10 Trinity Square. Elsewhere the slogan is `No admittance except on business'.
