How Interactive Brokers Group (IBKR) Has Been Trading Recently

Interactive Brokers Group (IBKR) has seen mixed share performance lately, with the stock down around 8% over the past month but showing a gain of roughly 9% in the past 3 months.

At a share price of US$68.45, Interactive Brokers Group has seen some recent pressure, with a 1-month share price return of an 8.4% decline. However, its 1-year total shareholder return of 54.5% and very large 5-year total shareholder return suggest longer term momentum has been much stronger than the latest pullback.

Earnings Show Exceptional Profitability Interactive Brokers (NASDAQ: IBKR) reported another standout quarter, reinforcing its position as one of the most operationally efficient brokerages in global finance. For Q3 2025, the company posted GAAP net revenues of $1.655 billion, up from $1.365 billion in the same quarter last year. Adjusted net revenues totaled $1.61 billion.
