UK-based CFDs and spreadbetting firm IG Group has experienced a pick-up in activity in recent months and said it is on track to report record quarterly revenues.The company said in September that sales had declined by 9% in its first quarter due to "particularly quiet" financial markets with volumes and volatility close to historic lows.However, after a subdued start to its financial year, IG said that client activity levels have "increased significantly" in the quarter ending 30 November.Results in October were particularly strong, "as the financial markets resented considerably more trading opportunities"."The company performed very well over this period and will achieve quarterly revenue ahead of its previous highest quarter at the end of the 2013 year," IG said." This will place IG in a robust position as it enters the second half of the financial year."Results for the first half are due out on 20 January 2015.
