1% yield), LLY (0. 5% yield) pay a dividend. NYXH, INSP do not pay a meaningful dividend and should not be held primarily for income.

For long-horizon retirement investors, Eli Lilly and Company (LLY) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (low volatility (β 0.

53), 0. 5% yield, +1485% 10Y return). Nyxoah S. A. (NYXH) carries a higher beta of 2. 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 (LLY: +1485%, NYXH: -94. 2%), 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.

Both stocks operate in the Healthcare sector, making this a peer-level intra-sector comparison — the same macro tailwinds and headwinds will affect both.

In terms of investment character: NYXH is a small-cap high-growth stock; LLY is a mega-cap high-growth stock; NVO is a mid-cap deep-value stock; INSP is a small-cap deep-value stock.
