Both have compounded well over 10 years (KO: +121. 1%, ARCT: -79. 4%), confirming both are viable long-term holds — but the lower-volatility option typically results in less emotional selling during corrections.

These companies operate in different sectors (ZBIO (Healthcare) and ARCT (Healthcare) and KO (Consumer Defensive) and PEP (Consumer Defensive) and MRNA (Healthcare)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.

In terms of investment character: ZBIO is a small-cap high-growth stock; ARCT is a small-cap quality compounder stock; KO is a large-cap quality compounder stock; PEP is a mid-cap income-oriented stock; MRNA is a mid-cap quality compounder stock. KO, PEP pay a dividend while ZBIO, ARCT, MRNA do not, making them suitable for different income and tax situations.
