Interactive Brokers falls 3.9% after quarterly results show mixed beats and a dividend hike

What happened

Interactive Brokers (IBKR) fell 3.9% on October 16, 2026, after reporting quarterly results, raising its dividend and disclosing product updates that investors said drove the session’s move. The stock closed at $82.69, capping a five-session drop of 5.9%, and trading volume was 1.9 times its 20-day average.

How big was the move

The decline was 1.6 times a typical daily move for this stock and was 3.9 percentage points worse than the Financial Services sector median, which was unchanged on the day. The S&P 500 fell 1.1% on the session and had fallen 1.9% over the last five sessions. The stock’s market sensitivity is a beta of 1.72, meaning the stock tends to move more than the market. In the past five years the stock had 44 sessions with a decline of at least 3.9%; twenty trading days later the median result was a gain of 3.2%, and 26 of 44 were higher.

The technical picture

The stock was 6.0% below its 20-day moving average and 8.4% below its 50-day moving average, while it was 0.4% above its 200-day moving average. The 50-day average is above the 200-day average, a sign of an established uptrend, and the stock had spent 139 consecutive trading days above the 200-day average. The Relative Strength Index (14 days) was 38, inside a neutral range between 30 and 70. The shares were 16.3% below the 52-week high and had fallen 6.4% over one month and 9.8% over three months, yet rose 18.5% over one year, which was 3.7 percentage points ahead of the S&P 500. Volatility was 39% annualized over 60 days, higher than 77% of its own readings over five years.

Fundamentals and valuation

For the four quarters through September 30, 2026, revenue was $11.60 billion, which grew 17.1% from a year earlier, and diluted earnings per share were $2.60, which rose 24.4% versus a year earlier. Gross margin was 94.6% (a year earlier: 89.3%) and operating margin was 87.0% (a year earlier: 85.5%). Return on invested capital was 3.6% and the balance sheet showed net cash of $5.92 billion. Share count over one year increased by 1.7%.

Those figures pointed to strong profitability by the company’s metrics: gross and operating margins widened year over year and management flagged rising net interest income, commission growth and expanding margin balances as drivers. At the same time, return on invested capital of 3.6% and share count growth of 1.7% temper the picture for investors focused on capital efficiency and dilution.

Valuation is rich by recent standards. The stock traded at 31.8 times trailing earnings and 30.8 times expected forward earnings, a price to trailing earnings that is higher than 71% of its own readings over the past five years (five-year median: 23.8 times earnings). PromtFinance scores ranked the company very highly for Growth (92) and Quality (98), strong for Revisions (81), neutral for Momentum (45), and very weak for Value (27) and Stability (23), underscoring a growth-at-a-premium profile.

Earnings and analyst expectations

Interactive Brokers reported on October 15, 2026, earnings per share of $0.67 against $0.67 expected, 0.3% above estimates. Reported diluted EPS for the quarter was $0.69 and adjusted EPS was $0.67, up from $0.59/$0.57 a year earlier, and the company noted record pre-tax profit and near-record adjusted net revenues, according to Business Wire and Seeking Alpha. Management highlighted rising net interest income, commission growth, expanding margin balances and customer-account growth on the call, according to Seeking Alpha and Zacks Investment Research.

Commissions rose 12% year-over-year to $602 million in the quarter, a detail the company flagged when discussing revenue mix. The typical two-day reaction after recent reports was a rise of 0.1%, but this session combined the beat-and-guide details with a dividend change and product updates, which together produced a sharper intraday move.

Analysts maintained a consensus rating of Buy, with 19 analysts providing ratings and 47% of the panel assigning ratings of Buy or better. The consensus price target was $107.57, which was 30.1% above the closing price. The stock’s market value stood at $151.84 billion.
