Approach 1: Interactive Brokers Group Excess Returns Analysis

The Excess Returns model looks at how much value a company creates above the return that shareholders require. It takes the equity investors put in, estimates a sustainable return on that equity, subtracts the required cost of equity, and then adds up those “excess” profits to arrive at an intrinsic value per share.

For Interactive Brokers Group, the model uses a Book Value of US$12.04 per share and a Stable EPS estimate of US$1.86 per share, based on the median return on equity from the past 5 years. The Average Return on Equity is 20.52%, while the Cost of Equity is US$0.74 per share. That results in an estimated Excess Return of US$1.12 per share. The Stable Book Value input is US$9.05 per share, drawn from the median book value over the past 5 years.

Using these inputs in the Excess Returns framework gives an intrinsic value of about US$32.67 per share. Compared with the recent price of US$71.21, the model output indicates that the stock is trading at a substantial premium, with an implied difference of roughly 118.0%.

Result: OVERVALUED

Approach 2: Interactive Brokers Group Price vs Earnings

P/E is a common way to value profitable companies because it links what you pay directly to the earnings each share generates. In general, higher growth expectations or lower perceived risk can justify a higher P/E ratio, while slower growth or higher risk usually point to a lower, more conservative multiple.

Interactive Brokers Group currently trades on a P/E of 32.25x. That sits below the Capital Markets industry average of 39.09x, but above the peer group average of 21.77x. This means the stock is priced higher than many peers while still below the wider industry level. Simply Wall St also calculates a Fair Ratio of 18.96x, which reflects what investors might typically pay for the company after considering factors such as its earnings growth profile, profit margins, industry, market cap and specific risks.

This Fair Ratio is more tailored than a simple comparison with peers or the industry, because it blends these company specific drivers into a single reference multiple. Comparing the Fair Ratio of 18.96x with the current P/E of 32.25x suggests the shares trade at a richer level than that customised benchmark.
