Amstrad Plc saw its shares tumble 23.5 pence to 182.5 pence after the company warned that weakness in the mobile phone market would prevent its Dancall unit making a profit in the current financial year. Chairman Alan Sugar said Dancall achieved sales of 100m British pounds in its first year of mass production, yet over-supply in the market would prevent the company making the healthy second-half profit that was expected.
