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

05)). ICON Public Limited Company (ICLR) carries a higher beta of 1. 60 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (PRA: -18. 8%, ICLR: +91. 0%), 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 (IQV (Healthcare) and CRL (Healthcare) and MEDP (Healthcare) and ICLR (Healthcare) and PRA (Financial Services)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.

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