Approach 1: Miami International Holdings Excess Returns Analysis

The Excess Returns model looks at how effectively Miami International Holdings turns shareholder capital into earnings above its cost of equity. Instead of focusing on cash flows, it compares the return generated on equity with the required return that investors expect.

For Miami International Holdings, book value is $11.31 per share and the stable book value used in the model is $5.59 per share, based on the median book value from the past 5 years. The model assumes stable EPS of $0.66 per share, sourced from the median return on equity over the same period, with an average return on equity of 11.73%.

The cost of equity is set at $0.44 per share, which implies an excess return of $0.22 per share. That spread between what equity is expected to earn and what it is required to earn is the core input for estimating intrinsic value under this framework.

Putting these inputs together, the Excess Returns valuation implies an intrinsic value of about $10.78 per share, compared with the current price around $49.77. In this model, the stock screens as very expensive.

Result: OVERVALUED

Our Excess Returns analysis suggests Miami International Holdings may be overvalued by 361.6%. Discover 51 high quality undervalued stocks or create your own screener to find better value opportunities.

Approach 2: Miami International Holdings Price vs Earnings

For a profitable company, the P/E ratio is a useful way to think about what you are paying for each dollar of earnings. It links the share price directly to earnings power, which many investors watch closely when they compare opportunities in the same sector.

What counts as a “normal” or “fair” P/E depends on how the market views a company’s growth prospects and risk. Higher expected growth or lower perceived risk can support a higher P/E, while slower expected growth or higher risk usually points to a lower P/E.

Miami International Holdings currently trades on a P/E of 38.80x. That sits just below the Capital Markets industry average P/E of 41.88x and above the peer group average of 10.01x, which suggests the stock is priced richer than many peers but not out of line with the broader industry.

Simply Wall St also uses a proprietary “Fair Ratio” for P/E, which aims to estimate what a suitable multiple could be after considering earnings growth, profit margins, risk profile, industry and market cap. This tends to be more tailored than a simple comparison with peers or industry averages, which may not share the same fundamentals.

In this case, there is no Fair Ratio available to compare with the current 38.80x P/E, so it is not possible to draw a firm conclusion on whether the stock looks overvalued, undervalued or about right using this framework.

Result: ABOUT RIGHT

Upgrade Your Decision Making: Choose your Miami International Holdings Narrative

Earlier it was mentioned that there is an even better way to understand valuation. Narratives bring this to life by letting you set a story for Miami International Holdings, link that story to explicit forecasts for revenue, earnings and margins, and see a fair value that you can compare with the current price, whether you lean toward a higher fair value around US$55.00 or a lower one near US$39.00. All of this is available within Simply Wall St's Community page, where Narratives are updated as fresh news or earnings arrive so your decisions always rest on a clear, numbers backed view of the story you believe.

For Miami International Holdings, however, we will make it really easy for you with previews of two leading Miami International Holdings Narratives:

Fair value in this bullish narrative: US$55.00 per share

Implied pricing gap vs last close: around 9.5% below that fair value

Revenue trend assumption: 22.9% annual revenue decline

• Assumes MIAX’s multi listed options, complex orders and short dated contracts support higher transaction fees and operating leverage over time.
• Sees futures, Bloomberg index contracts and international listings as important new lines that could widen revenue sources and earnings power.
• Backs a higher long term P/E multiple and margin expansion, with earnings and cash generation absorbing today’s fixed cost base.

Fair value in this bearish narrative: US$39.00 per share

Implied pricing gap vs last close: around 27.7% above that fair value

Revenue trend assumption: 22.7% annual revenue decline

• Highlights dependence on elevated options and futures volumes, with a concern that lower volatility or softer retail activity could pressure revenues.
• Flags ongoing technology and expansion spend as a headwind for margins if new products and geographies do not scale as expected.
• Points to competitive pricing, equity based compensation and regulatory risk as factors that could cap earnings per share and justify a lower valuation.

Neither narrative is automatically “right,” but together they set a clear range for what different analyst cohorts think Miami International Holdings could be worth. The key is deciding which assumptions line up more closely with your own view of its volumes, margins and capital needs, then using that to frame your next move.
