Analysts rate Johnson & Johnson (JNJ) a "Buy" — based on 40 analyst ratings — the highest consensus in this comparison.

4x versus Johnson & Johnson at 38. 4x. On forward P/E, Pfizer Inc. is actually cheaper at 8. 9x — notably different from the trailing picture, reflecting expected earnings growth. The PEG ratio (P/E divided by earnings growth rate) is the most growth-adjusted single valuation metric: IQVIA Holdings Inc. wins at 0. 35x versus Johnson & Johnson's 34. 17x — a PEG below 1. 0 traditionally signals the market is underpricing earnings growth.

Higher growth typically commands a higher valuation multiple — check whether the premium P/E or P/S is justified by the growth rate using the PEG ratio.

In this comparison, PFE (6.

5% yield), MRK (2. 9% yield), ABT (2. 5% yield), JNJ (2. 2% yield) pay a dividend. IQV does not pay a meaningful dividend and should not be held primarily for income.

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

06), 2. 2% yield, +132. 3% 10Y return). Both have compounded well over 10 years (JNJ: +132. 3%, IQV: +166. 5%), 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: JNJ is a large-cap quality compounder stock; ABT is a mid-cap deep-value stock; PFE is a mid-cap income-oriented stock; MRK is a large-cap deep-value stock; IQV is a mid-cap quality compounder stock. JNJ, ABT, PFE, MRK pay a dividend while IQV does not, making them suitable for different income and tax situations. 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.
