In this comparison, PFE (6.

7% yield), BMY (4. 4% yield), MRK (2. 9% yield), JNJ (2. 2% yield) pay a dividend. NBTX does not pay a meaningful dividend and should not be held primarily for income.

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

04), 2. 2% yield, +131. 3% 10Y return). Nanobiotix S. A. (NBTX) carries a higher beta of 2. 09 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (JNJ: +131. 3%, NBTX: +167. 9%), 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: NBTX is a small-cap quality compounder stock; MRK is a large-cap deep-value stock; BMY is a mid-cap deep-value stock; PFE is a mid-cap income-oriented stock; JNJ is a large-cap quality compounder stock. MRK, BMY, PFE, JNJ pay a dividend while NBTX does not, making them suitable for different income and tax situations. 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.
