Another View on Interactive Brokers Group Using P/E

The earlier fair value of $106.97 paints Interactive Brokers Group as undervalued. A simple P/E check tells a different story. IBKR trades on 36.1x earnings, above its own fair ratio of 19.9x and above peer averages of 25.2x, which points to a richer price that could carry downside risk if expectations slip.

For investors comparing these mixed signals, the question is whether the growth narrative and earnings quality justify paying well above that fair ratio, or whether patience makes more sense if the market eventually leans closer to those lower multiples.
