Interactive Brokers Group has delivered very strong long term share gains, which puts fresh attention on a basic question for anyone looking at the stock today. Is the current price adequately supported by the broker's earnings power, or has enthusiasm for its business moved ahead of what the income statement can justify?
The issue now is whether the earnings that Interactive Brokers generates today, and what investors expect it to produce next, are enough to justify the current share price.
If you are weighing Interactive Brokers Group against other opportunities that also turn on earnings power, it helps to see how similar ideas line up across 29 high quality undervalued stocks.
For a broker like Interactive Brokers Group that leans heavily on fee and interest income, the P/E ratio gives a straightforward read on what investors are paying for each dollar of earnings. The stock trades on a P/E of about 35.3x, which is higher than both the Capital Markets industry average of roughly 39.7x and the peer group at around 23.3x, so the market is attaching a relatively rich earnings tag compared with many similar businesses.
The fair P/E level implied by the valuation model, which blends the company’s projected returns, risk profile and sector norms, sits below the current multiple. As a result, the shares screen as overvalued on this framework. Because Interactive Brokers is set to discuss its third quarter numbers on October 15, 2026, the upcoming call may test whether recent results and guidance line up with a valuation that already asks buyers to pay a premium earnings multiple. Explore the numbers behind Interactive Brokers Group's P/E valuation.
