The PEG ratio (P/E divided by earnings growth rate) is the most growth-adjusted single valuation metric: Zoetis Inc. wins at 0. 99x versus IDEXX Laboratories, Inc. 's 2. 68x — a PEG below 1. 0 traditionally signals the market is underpricing earnings growth.

4% yield) pays a dividend. ICCC, NEOG, IDXX, NVAX do not pay a meaningful dividend and should not be held primarily for income.

For long-horizon retirement investors, Zoetis Inc.

(ZTS) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (low volatility (β 0. 88), 2. 4% yield). Novavax, Inc. (NVAX) carries a higher beta of 2. 22 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (ZTS: +97. 8%, NVAX: -89. 4%), 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: ICCC is a small-cap high-growth stock; NEOG is a small-cap quality compounder stock; IDXX is a mid-cap quality compounder stock; NVAX is a small-cap high-growth stock; ZTS is a mid-cap deep-value stock. ZTS pays a dividend while ICCC, NEOG, IDXX, NVAX do not, making them suitable for different income and tax situations.
