Shares in Ericsson fell 15 per cent on Tuesday after the Swedish group issued another damaging warning on its finances and said the telecoms equipment market was shrinking faster than anticipated.Second-quarter results from the company showed sales down 8 per cent to SKr50bn ($6bn), or a fall of 13 per cent adjusting for currency movements, while its operating loss widened to SKr1.2bn. Yet it was the broader outlook that caused more concern. The company said the radio access network equipment market, its core business, was now expected to decline this year by a “high single-digit percentage” compared with its previous estimate of a fall of between 2 per cent and 6 per cent. Ericsson also said it saw an increased risk of further market and customer project “adjustments” — some big contracts proving to be less lucrative then expected — that could hit operating profit by between SKr3bn and SKr5bn.The shares fell 15 per cent to SKr51.40 and have now lost around 50 per cent of their value since the start of 2015.
