Plus500 shares crashed from above 1,600p to below 500p in the first half of last year after February's results revealed that tighter European regulation on CFD trading had hit revenues more than expected, with a profit warning days later on the back of an accounting error. Rather than incurring zero losses from client trading, as its results had first indicated, the FTSE 250 group revealed that it had instead suffered a US$103mln hit. "We finished the year in good financial and operational shape following a period of change for the industry, which has provided a more certain regulatory outlook for Plus500 ," said chief executive Asaf Elimelech in a statement on Monday.
