GEC Plc’s shares are a pretty sleepy market these days so the fact that they jumped 13 pence to 211 yesterday on phenomenal volume of 34m shares traded is worthy of note: the excitement was caused by gossip in the market that Hanson Trust had taken a stake: if anyone tells us Hanson is preparing a bid, we’ll say pull the other one but the fact that Hanson sees the company as a worthwhile investment at current prices justifies the jump.
