(INMD) is the cheapest at 9. 7x versus Progyny, Inc. at 29. 5x. On forward P/E, InMode Ltd. is actually cheaper at 10. 3x. The PEG ratio (P/E divided by earnings growth rate) is the most growth-adjusted single valuation metric: InMode Ltd. wins at 1. 04x versus Progyny, Inc. 's 2. 99x — a reasonable growth-adjusted valuation.

(NTRA) delivered a total return of +115. 9%, compared to -100. 0% for INVO Fertility, Inc. (IVF). Over 10 years, the gap is even starker: NTRA returned +1835% versus IVF's -100. 0%. Past returns do not guarantee future results, and the stock with the higher historical return may already have its best growth priced in.

By beta (market sensitivity over 5 years), Progyny, Inc.

(PGNY) is the lower-risk stock at 0. 79β versus Marathon Digital Holdings, Inc. 's 3. 10β — meaning MARA is approximately 294% more volatile than PGNY relative to the S&P 500.

Higher growth typically commands a higher valuation multiple — check whether the premium P/E or P/S is justified by the growth rate using the PEG ratio.

InMode Ltd.

(INMD) is the more profitable company, earning 25. 3% net margin versus -144. 6% for Marathon Digital Holdings, Inc. — meaning it keeps 25. 3% of every revenue dollar as bottom-line profit. Operating margin tells a similar story: INMD leads at 23. 0% versus -124. 4% for IVF. At the gross margin level — before operating expenses — INMD leads at 78. 5%, reflecting greater pricing power or product mix advantage. Stronger margins indicate durable pricing power, lower cost of revenue, or higher mix of software/services. They are one of the clearest signs of business quality.

The PEG ratio (forward P/E divided by expected earnings growth rate) is the most precise measure of undervaluation relative to growth potential.

By this metric, InMode Ltd. (INMD) is the more undervalued stock at a PEG of 1. 04x versus Progyny, Inc. 's 2. 99x. A PEG below 1. 5 suggests fair-to-attractive pricing relative to expected growth.

None of the stocks in this comparison currently pay a material dividend.

All are effectively zero-yield and should be held for capital appreciation rather than income.

For long-horizon retirement investors, Natera, Inc.

(NTRA) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (low volatility (β 1. 17), +1835% 10Y return). Marathon Digital Holdings, Inc. (MARA) carries a higher beta of 3. 10 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (NTRA: +1835%, MARA: -50. 7%), confirming both are viable long-term holds — but the lower-volatility option typically results in less emotional selling during corrections. Retirement portfolios generally favour predictability over maximum returns. Consult a financial advisor before making allocation decisions.

These companies operate in different sectors (IVF (Healthcare) and NTRA (Healthcare) and PGNY (Healthcare) and INMD (Healthcare) and MARA (Financial Services)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.

In terms of investment character: IVF is a small-cap high-growth stock; NTRA is a mid-cap high-growth stock; PGNY is a small-cap quality compounder stock; INMD is a small-cap deep-value stock; MARA is a small-cap high-growth stock. These fundamental differences mean investors should not choose between them on a single metric — the "better stock" depends entirely on which of these characteristics aligns with your investment strategy.
