Plus500 Ltd (LON:PLUS) said trading activity has dropped back after the huge volumes seen at the start of the COVID-19 pandemic a year ago.
Revenues at the financial dealing platform in the half-year to June 2021 were US$346mln, against US$564mln in the same period in 2020 and US$148mln in 2019.
Second-quarter revenues were US$143mln, down from US$248mln in the comparable three months, in what the company described as a 'relatively stable market environment compared to recent periods and against a record performance during 2020'.
Plus500 added it had still seen healthy numbers of new customers sign up with 137,000 joining during the half-year, which was well above the second half of 2020.
The acquisition of futures and options group Cunningham in the US should complete shortly, it said, while a new share dealing platform launched earlier this month, though there was an impact from regulatory changes in Australia which it said it is continuing to monitor.
David Zruia, chief executive, said: "Plus500's excellent performance so far in 2021 was driven by the strength and agility of our technology and its ability to respond rapidly to market developments, news events and customer requirements.”
