Recent share performance and business scale

Interactive Brokers Group (IBKR) has drawn fresh attention after a strong run in its share price, with the stock showing positive returns over the past week, month and past 3 months.

At a last close of US$81.72, the company carries a market value of about US$136.5b. Over the past year, total return is reported at 83%, with 3 year and 5 year total returns also very large.

The recent 1 month share price return of 20.64% and year to date share price return of 21.55%, alongside a 1 year total shareholder return of 83%, suggest momentum has been building both in the short term and over a longer period.

With Interactive Brokers reporting US$6.4b in revenue, US$1.0b in net income, and trading only slightly below the average analyst price target, investors may question whether the stock is still undervalued or if markets are already pricing in future growth.

Most Popular Narrative: 5% Undervalued

Interactive Brokers Group's most followed narrative points to a fair value of $86.00, slightly above the last close of $81.72. This frames the stock as modestly discounted rather than deeply mispriced.

The ongoing popularity of investing with global interest from investors who increasingly want broad portfolios and international access is expected to drive sustained account growth, attracting both individual and institutional investors and boosting overall revenue. The successful addition of 178,000 new accounts in the quarter showcases the platform's ability to attract new users and deepen market penetration, likely catalyzing future earnings growth through both increased trading volumes and asset management fees.

Curious what kind of revenue trajectory and margin profile sit behind that fair value, and how a relatively high future earnings multiple fits into the story? The full narrative spells out the growth runway, profitability expectations and valuation bridge that underpin the $86 mark, including how analysts balance expansion ambitions with execution risk and funding assumptions.

Result: Fair Value of $86 (UNDERVALUED)

However, the story can shift quickly if trading volumes soften for a sustained period or if rising competition abroad limits the impact of IBKR’s international expansion.
