(AEYE) is the stronger pick with 14. 5% revenue growth year-over-year, versus -32. 4% for T Stamp Inc. (IDAI). The "better buy" depends entirely on your goals: growth investors should weight revenue trajectory, value investors should weight P/E and PEG, and income investors should weight dividend yield and streak.

Over the past 5 years, AudioEye, Inc.

(AEYE) delivered a total return of -60. 2%, compared to -99. 1% for NRx Pharmaceuticals, Inc. (NRXP). Over 10 years, the gap is even starker: IDAI returned +102. 4% versus NRXP's -96. 8%. 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), XTL Biopharmaceuticals Ltd.

(XTLB) is the lower-risk stock at 1. 71β versus AudioEye, Inc. 's 2. 29β — meaning AEYE is approximately 34% more volatile than XTLB relative to the S&P 500. On balance sheet safety, XTL Biopharmaceuticals Ltd. (XTLB) carries a lower debt/equity ratio of 3% versus 130% for T Stamp Inc. — giving it more financial flexibility in a downturn.

Over a 3-year CAGR, AEYE leads at 10. 5% annualised revenue growth. 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.

AudioEye, Inc.

(AEYE) is the more profitable company, earning -7. 6% net margin versus -23. 4% for NRx Pharmaceuticals, Inc. — meaning it keeps -7. 6% of every revenue dollar as bottom-line profit. Operating margin tells a similar story: AEYE leads at -7. 9% versus -1324. 4% for NRXP.

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

For long-horizon retirement investors, XTL Biopharmaceuticals Ltd.

(XTLB) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding. NRx Pharmaceuticals, Inc. (NRXP) carries a higher beta of 1. 91 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (XTLB: -87. 3%, NRXP: -96. 8%), 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 (IDAI (Technology) and XTLB (Healthcare) and AEYE (Technology) and NRXP (Healthcare)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.

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.
