Buying orders flooded in for IT shares on the London Stock Exchange, as investors decided to follow US trends and abandon normal sober judgements when companies with any connections with the internet are concerned. Shares in Netcall Plc leapt 70% to 85 pence as word spread there could be a big future in the company’s business in the development, supply and maintenance of computer telephony software. Netcall directors issued a statement saying they know of no specific reason other than intense current market speculation on values of internet related shares. The board claimed that increasing recognition of the company’s ability to fuse the power of telecommunications with e-commerce could also be a factor. On-line Plc, a computer games company whose shares could be picked up for 16.5 pence two weeks ago, rose another 50% yesterday to a new peak of 260 pence.
