In this comparison, ABBV (2.

9% yield), GILD (2. 5% yield), KO (2. 5% yield) pay a dividend. IMUX, BIIB do not pay a meaningful dividend and should not be held primarily for income.

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

20), 2. 5% yield, +121. 1% 10Y return). Immunic, Inc. (IMUX) carries a higher beta of 1. 80 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (KO: +121. 1%, IMUX: -99. 6%), 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 (IMUX (Healthcare) and ABBV (Healthcare) and KO (Consumer Defensive) and GILD (Healthcare) and BIIB (Healthcare)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.

ABBV, KO, GILD pay a dividend while IMUX, BIIB do 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.
