The news that Amstrad Plc had a hot new personal communicator product on the way should have been in the market for a couple of weeks now – we reported it on March 1 (CI No 2,117) but these things take time to filter through and it was only on Tuesday that the shares really began to respond, putting on 3.75 pence; they added another 3.5 pence to 34.75 pence yesterday morning.
