Shares in spreadbetting firm Plus500 were up almost 13 per cent this morning after the group reported a record first half performance.
Underlying profit doubled to $118.5m (£90.8m) during the first half.
Revenues grew 19 per cent to $188.4m, as the number of new customers in the second quarter grew 43 per cent to 31,671.
The group also reported that it had managed to decrease the cost of acquiring each new customer by 37 per cent to $836 per person.
Why it's interesting
After taking a hammering at the end of last year, Plus500 shares have recovered lost ground and are edging towards one-year highs.
The firm's stock was hit at the end of December when the Financial Conduct Authority (FCA) revealed a crackdown on the spreadbetting sector. Plus500, alongside listed rivals IG Group and CMC Markets, saw a huge chunk wiped off its market capitalisation when the plans were announced last December.
Regulators are eager to protect less sophisticated investors. They proposed capping the level of risk investors can take and banning new customer offers.
The FCA has now handed over the reins to European authorities, which plan to introduce reforms in early 2018.
What the company said
Chief executive Asaf Elimelech said: "Plus500 achieved record first half results, significantly ahead of market expectations. New Customers continue to join and the proportion of both new and active customers originating from well-regulated markets is growing and continues to expand the group's community of high-quality customers.
