(ABBV) delivered a total return of +123. 7%, compared to -98. 7% for Kezar Life Sciences, Inc. (KZR). Over 10 years, the gap is even starker: ABBV returned +362. 2% versus KZR's -99. 6%.

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.

Both stocks trade at elevated growth-adjusted valuations, so expected growth needs to materialise.

In this comparison, BMY (4.

3% yield), ABBV (2. 9% yield), AMGN (2. 7% yield), KO (2. 5% yield), REGN (0. 6% yield) pay a dividend. KZR does 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). Both have compounded well over 10 years (KO: +121. 1%, KZR: -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 (KZR (Healthcare) and ABBV (Healthcare) and BMY (Healthcare) and AMGN (Healthcare) and REGN (Healthcare) and KO (Consumer Defensive)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.

In terms of investment character: KZR is a small-cap quality compounder stock; ABBV is a large-cap quality compounder stock; BMY is a mid-cap deep-value stock; AMGN is a mid-cap quality compounder stock; REGN is a mid-cap deep-value stock; KO is a large-cap quality compounder stock. ABBV, BMY, AMGN, REGN, KO pay a dividend while KZR 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.
