Miami International Holdings (MIAX): Evaluating Valuation Following Strong Recent Share Price Gains

Miami International Holdings (MIAX) is drawing attention as investors take a closer look at its recent stock moves. After a month of double-digit gains, there is fresh interest in how the company’s momentum could impact its valuation.

See our latest analysis for Miami International Holdings.

Momentum in Miami International Holdings has clearly been building, with a 15% 1-month share price return and a strong 40% year-to-date rise, putting the stock firmly on investors’ radars. While recent days have brought a modest pullback, the surge over the past few weeks suggests confidence in the company’s growth prospects or a shift in risk perception is fueling this attention.

But with annual revenue declining even as net income accelerates, and shares now just shy of analyst targets, the real question is whether Miami International Holdings represents an overlooked bargain or if future gains are already reflected in the current price.

Price-to-Sales of 3x: Is it justified?

MIAX trades at a price-to-sales ratio of 3x, well below the average for its peers and the US Capital Markets industry. With the last close price at $43.11, this multiple suggests the market currently values the company’s revenues much more conservatively compared to others in the sector.

The price-to-sales ratio measures how much investors are willing to pay per dollar of sales. This makes it especially relevant for financial firms like MIAX, where earnings can be volatile but sales provide a baseline for comparison. A low multiple can either signal overlooked value or underlying concerns about future growth.

Here, MIAX’s 3x price-to-sales stands out against both its peer average (9.2x) and the broader industry average (3.9x), highlighting a significant discount. The gap may close if market confidence in its growth prospects strengthens or if earnings forecasts are realized.

Result: Price-to-Sales of 3x (UNDERVALUED)

However, persistent annual revenue declines or a market re-rating that moves closer to analyst targets could challenge the undervalued thesis going forward.

Another View: What Does Our DCF Model Say?

Looking at MIAX using the SWS DCF model provides a much less optimistic perspective. The stock’s last close at $43.11 is significantly higher than our estimated fair value of $7.49. On this basis, shares would appear overvalued, not undervalued. Is the market pricing in something beyond current expectations, or is caution warranted here?

Look into how the SWS DCF model arrives at its fair value.
