IG Group shares reached an all-time peak on Tuesday after the online trading platform lifted its outlook following a robust first quarter. The stock jumped 11% to 17.46 pounds in London trading, extending gains to 33% year-to-date and topping the FTSE 100 leaderboard.

The company reported first-quarter organic revenue climbed 19% to 331.2 million pounds ($445 million), though net interest income dropped 22% to 24.7 million pounds as lower interest rates took their toll. This revenue beat provided the foundation for the guidance upgrade that sent investors racing to bid up the shares.

Chief Executive Breon Corcoran credited the performance to IG Group's expanded product suite and favorable market conditions that have driven client activity higher. The strong start to the year positions the firm well against competitors in the competitive online trading space, where market volatility and retail investor participation remain key growth drivers.
