(INVA) is the cheapest at 6. 9x versus McKesson Corporation at 29. 2x. 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: McKesson Corporation wins at 0. 49x versus Innoviva, Inc. 's 1. 15x — a PEG below 1. 0 traditionally signals the market is underpricing earnings growth.

Over the past 5 years, McKesson Corporation (MCK) delivered a total return of +286.

9%, compared to -13. 3% for Pfizer Inc. (PFE). Over 10 years, the gap is even starker: AXSM returned +1886% versus PFE's +29. 6%. Past returns do not guarantee future results, and the stock with the higher historical return may already have its best growth priced in.

Over a 3-year CAGR, AXSM leads at 133. 7% annualised revenue 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.

5% yield), MCK (0. 4% yield) pay a dividend. RLMD, INVA, AXSM do not pay a meaningful dividend and should not be held primarily for income.

For long-horizon retirement investors, Axsome Therapeutics, Inc.

(AXSM) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (low volatility (β 0. 69), +1886% 10Y return). Both have compounded well over 10 years (AXSM: +1886%, RLMD: +312. 8%), 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: RLMD is a small-cap quality compounder stock; INVA is a small-cap high-growth stock; PFE is a mid-cap income-oriented stock; AXSM is a mid-cap high-growth stock; MCK is a mid-cap high-growth stock. PFE pays a dividend while RLMD, INVA, AXSM, MCK do 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.
