For long-horizon retirement investors, Medpace Holdings, Inc.

(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). 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 (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. Retirement portfolios generally favour predictability over maximum returns. Consult a financial advisor before making allocation decisions.

Both stocks operate in the Healthcare sector, making this a peer-level intra-sector comparison — the same macro tailwinds and headwinds will affect both.

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