(MEDP) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (low volatility (β 1. 26), +1443% 10Y return).

Both have compounded well over 10 years (MEDP: +1443%, ICLR: +91. 0%), 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 (RFL (Real Estate) and IQV (Healthcare) and MEDP (Healthcare) and CRL (Healthcare) and ICLR (Healthcare)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.

In terms of investment character: RFL is a small-cap high-growth stock; IQV is a mid-cap quality compounder stock; MEDP is a mid-cap high-growth stock; CRL is a small-cap quality compounder stock; ICLR is a small-cap deep-value stock. 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.
